Anthocyanins as Natural Plant-derived Antifungal Agents
By: Nirmalkar Vaishali , Ansari Shahana , Shaikh Asfiya , Momin Naziya
Page No : 29-38
Abstract
Anthocyanins are polyphenolic compounds found as natural pigments in various parts of plants that share the same diphenyl propane skeleton (C6 C3 C6 ) and are collectively known as flavonoids. They are water-soluble pigments responsible for the blue, purple, and red color of various plant parts and are particularly abundant in fruits, flowers, and vegetables. These pigments are natural colorants that are low to non-toxic. They also show antifungal, antibacterial, antioxidant, and food preservative properties. This study aims to perform in vitro analysis of the antifungal activity of anthocyanins extracted from different plant materials. Anthocyanins were extracted in acetone and acidified methanol. For qualitative determination of anthocyanins, thin layer chromatography was used whereas for quantitative determination pH differential method was used. The antifungal potential of anthocyanins was determined using the MIC and agar well diffusion methods against Penicillium sp. and Aspergillus sp. Acetone extract exhibited higher antifungal potential compared to acidified methanol extract against both fungal strains. It is suggested that anthocyanins, being strong antifungal agents, can be used to prevent fungal spoilage and deterioration of processed foods.

Page No : 95-103
Abstract
Plant latex is a sap that is exuded from damaged vein. It is kept in a tissue specialized in exuding latex called laticifer and is kept inside laticifer cells. It works as an efficient defence system against herbivorous insects. Laticifer is a general term applied to a large and heterogenous group of cell types. In Pedilanthus tithymaloides the laticifers are an elongated; anastomosing network of cells which are non-articulated branched and are commonly located in the outer part of the vascular cylinder. Laticifers extend throughout the length of the plants.

Page No : 163-175
Abstract
The present study was carried out to investigate the orchid diversity in community managed subtropical broad-leaved forests in Khasi Hills of Meghalaya. A total of 87 community forests were surveyed in Khasi Hills. The study revealed the presence of 123 species belonging to 54 genera. The highest numbers of species (66) were recorded in sacred forests, followed by reserved (51) and village (32) forests. Majority of the recorded species (87) were epiphytic and 36 were terrestrial. Of all the species, 28 (22.76%) were recorded as endemic and 12 (9.76%) were rare. Dendrobium with 19 species was the dominant genera followed by Coelogyne with 11 species. Owing to a number of anthropogenic disturbances followed by habitat loss, these species are subjected to continuous threat, hence warrants immediate conservation actions. Therefore, it is suggested that mass propagation, through conventional and tissue culture techniques should be adopted to conserve the dwindling orchid diversity of the state.

Citrus Fruit Peels: From Waste to Worth
By: Nidhi Parmar , V. H.Patel , Viraj Roghelia
Page No : 249-256
Abstract
Citrus fruits are most commonly consumed fruits. However, the peels of these fruits yield a huge waste. The peels also contain important phytoconstituents. This study aimed to investigate the antioxidant properties of peels of two selected citrus fruits (sweet lime and lemon). The peels were extracted using four solvents namely methanol, ethanol, acetone and distilled water. The extracts were analysed for total phenolic content, flavonoid content, DPPH radical scavenging activity and ferric ion reducing antioxidant power (FRAP). The result revealed that highest antioxidant profile was found for methanol extract of both sweet lime peel and lemon peel as compared to other extracts. The extracts of peels of sweet lime possessed higher total phenol, flavonoid and FRAP. The antioxidant capacity in terms of DPPH RSA and FRAP were attributed mainly to total phenolics as compared to flavonoids for both the peels. The higher antioxidant potential of peels of selected citrus fruits make them key ingredient for the development of functional foods and other supplementary products.

By: S. Swathi Lakshmi , T. Ponrathy
Page No : 87-90
Abstract
The palm tree, Borassus flabellifer Linn., is an erect and celestial tree with more than 800 diverse applications. It is the official tree of the Indian state, Tamil Nadu. The aim of this study was to investigate the antidiabetic and antioxidant properties of Palmyra underground sprouts. Palmyra sprout was also tested for its anti-inflammatory properties. All the assays were conducted on powder of boiled Palmyra sprout extracts in chloroform. The antidiabetic potentials were assessed using ?-amylase, as a target enzyme. Colorimetric antioxidation potentials were determined by phosphomolybdenum method. The iron-ferrozine absorbance at 562 nm was used to calculate the metal chelating assay. An in-vitro protein denaturation inhibition assay was used to assess the anti-inflammatory property. The Palmyra sprout extracts inhibited ?-amylase, one of the key enzymes involved in starch digestion and blood glucose regulation. The Antioxidant potential of the sample was recorded as 96% and Fe2+ ion-chelating activities of the sample was also detected. The percentage inhibition of protein denaturation in this underground sprout was evaluated as 91.18. These results show that Borassus flabellifer Linn. underground sprout extract has antidiabetic, metal chelating, antioxidant, and anti-inflammatory properties, and hence has a lot of potential as a natural health product source.

Abstract
Banded Leaf and Sheath Blight (BLSB) disease of Maize Caused by Rhizoctonia solani f. sp. sasakii is one of the most severe disease causing serious yield losses each year. In recent years, Rhizoctonia solani is fitting more prevalent in agricultural areas where climate change is leading to higher temperatures. We conducted a experiment in which, a series of fungal collection, isolation and identification from the infected plant parts. The plant showed typical symptoms like the disease lesion are characterized by the presence of alternate bleached area or zones, which are initially water soaked and narrow purple brown bends oriented perpendicular to long axis of leaves or leaf sheath. The infected isolates may be seen on the affected tissues after reinoculation and produced mycelia growth and sclerotia on both plants and culture plates. On re-isolation it was found that the fungus was identical to the original isolate. It was observed that the infection was much higher in inoculated plants as compared to control.

Pheno-biological Diversity of Leaf Litter Macrofungi in Some Forests of West Bengal
By: Gouri Das , Parichay Chakraborty
Page No : 139-150
Abstract
In forest ecology and biodiversity, macrofungi occupy important place. Apart from soil nutrients, pH, soil moisture, depth of litter on the forest floor, a number of factors influence diversity of litter fungi as litter decomposition is a highly complex process mediated by various fungal taxa. In the present study physical and chemical attributes of leaf litter from different tree species in the forests of Dakshin Dinajpur district, West Bengal were observed and an assemblage of 11 macrofungal taxa belonging to 7 different families like Agaricaceae, Amanitaceae, Tricholomataceae, Omphalotaceae Marasmiaceae, Aphelariaceae, Psathyrellaceae have been found. These macrofungi were collected from Danga, Dogachhi, Kasiadanga, Barakasipur of Balurghat beat and Abhirampur, Asair, Erenda forestof Tapan beat. This investigation being the pioneering one in this area, also revealed high degree of host and part of the leaf specificity in some cases. The heterogeneity in the abiotic environment may have indirect or direct effect on the distribution of litter fungi in the litter profile. Interestingly, the occurrence of Aphelariaceae (Aphelaria sp.) was restricted to the litter layers of Erenda forest floor only. For systematic random sampling, field trips were conducted at 60 plots with 4 transects during summer, rainy, autumn and spring over last 3 years. All the collected samples were worked out thoroughly, identified and preserved in the laboratory. The data generated in the study will certainly enlighten the domain of mycological diversity of litter fungi.

Abstract
Tea plant is one of the major cash crops in Northeast India and tea leaves is a popular beverage cherished as a part of a healthy human diet. Tea plant being an economically important crop it is necessary to understand the soil fungal population as soil fungi are key drivers of plant productivity. This present study is conducted in the soil samples collected seasonally from the tea cultivated area of Mokokchung district, Nagaland, India. A total of 60 fungal species under 26 genera were isolated from the study site and colony forming units (CFU), relative density (RD), relative frequency (RF) and important value index were calculated. The highest fungal counts were recorded during the spring season with 8.2 x 106 CFUg-1 and lowest fungal counts were recorded in the winter season with 2.7 x 106 CFUg-1. Highest IVI was recorded in Aspergillus niger (8.09) followed by A. flavus (6.58). Dominance of Aspergillus may be attributed to the antagonistic nature exhibited by these genera against other fungi.

By: Mahavir Gosavi , Ashwini Deshpande
Page No : 159-163
Abstract
Arbuscular mycorrhizae (AM) are the obligate symbionts, forming natural, beneficial relationships with higher plants. About 80% of plants are colonized by AM fungi which belong to Glomeromycota (Family - Endogonaceae). In soil microorganisms, AM fungi are commonly studied because of their capacity to support plant tolerance under polluted and toxic conditions. The current study deals with the exclusive survey of fifteen industrial sites from MIDC, Dombivli (East). The sites were investigated to study diversity of AM fungi with respect to rhizosphere soil analysis for subsequent spore density and identification. Spores of Glomus, Acaulospora, and Gigaspora were observed. The observed species were also detected in root colonization analysis, using standard staining methods. The spore density was highest for Glomus. The species recorded and identified from genus Glomus are G. aggregatum, G. albidum, G. australe, G. deserticola, G. fasciculatum, G. fulvus, G. geosporum, G. intraradices, G. microcarpum, G. multicaule and G. occultum along with species of Acaulospora like A. foveata, A. mellea, A. scrobiculata and Gigaspora margarita.

Abstract
Wood-rot fungi are known to be saprophytic, they are grown on most of the organic and decaying matters. These fungi have an ability to produce coloured pigments in in-vitro cultures when they are grown in specific growth media. The pigment producing capacity of such fungi depends on the composition and pH of media. Various coloured compounds can be obtained by changing the concentration of component of growth media for such fungi. The most commonly used growth media for in-vitro culturing of woodrot fungi are Potato dextrose agar (PDA) and Potato dextrose broth (PDB) and Sabouraud dextrose agar (SDA) and Sabouraud dextrose broth (SDB). Current study conducted of Ganoderma lucidum, a commonly occurring wood-rot fungi, it has been observed that the production of pigment in G. lucidum was dependent on various growth media and their components. The fungus forms white patchy, non-pigmented colonies when cultured on PDA medium whereas it showed pigmented growth on SDA medium. Further, by replacing each nutrient component in the growth medium one by one, it has been determined that the component plays a vital role in pigment production by G. lucidum. It has been remarkably established that pigment production in the fungus is totally dependent on peptone concentration. Additionally, Nature of pigment has been studied by carbon and hydrogen ratio which has been in correlation with the substrate provided in the growth medium. The pigment obtained by the study were further evaluated for thermal and pH stability which showed promising results as pigment was unaffected till 60

Page No : 195-204
Abstract
Asymbiotic seed germination has revolutionised the commercial production of exotic orchids as well as conservation of rare and endemic ones. However, the success of the process largely depends on the sterilisation procedure adopted to disinfect the minute dust like orchid seeds. The present study incorporates the technique of centrifugation method to successfully disinfect the exposed seeds obtained from the dehisced capsule of Phaius tankervilleae, which is an ornamental orchid endemic to Northeast India. The seeds of P. tankervilleae showed 100% disinfection as well as germination efficiency (with 5% NaOCl and 8 mins exposure) with no risk of physical damage to the seeds due to the centrifugation process (4 mins at 4000 rpm under 4?C). Inoculated seeds showed the first sign of swollen embryos (PLBs) after 5 weeks of culture in Murashige and Skoog (1962) (MS) medium. PLBs obtained were subcultured on MS medium supplemented with different plant growth regulators for healthy proliferation and shoot multiplication. MS medium supplemented with 2 mg/L each of BAP and KN resulted in best overall shoot and root development. Therefore, the present study reports a simple yet effective sterilisation procedure to disinfect exposed P. tankervilleae seeds which is quick, easy and very efficient for mass scale propagation as well as ex-situ conservation of this valuable orchid species and other orchid species as well.

Abstract
Information about the impacts of different land-use systems on the physical properties of soil is essential for the sustainable utilization of existing soil resources. The main objective of this study was to examine the variation in selected physical properties across the different prevailing land-use systems in the Sub Humid Southern Plains and Aravalli hills of Rajasthan. A total of 120 composite soil samples were collected for laboratory analysis from barren, cultivated, agri-horticulture, horticulture, grass, and natural forest land-use systems by four different soil depths (0-20, 20-40, 40-60 and 60-80 cm) with five replications. The two-way analysis of variance (Two ways ANOVA) was used to test the effect of different land-use systems and soil depths on measurable soil physical properties. The results of the study revealed that the soil separates (sand, silt, and clay fractions) were not differed significantly across the land use systems as the texture is an inherent property of soil that cannot be changed easily by agricultural management practices. However, soil depth was affected significantly to the particle size distribution under studied land use systems. The mean bulk density of the soil varied from 1.51 to 1.62 Mg m-3 and the mean total porosity ranged from 38.56 to 41.77%. The highest plant available water (0.362 cm3 -H2 Ocm-3 Soil) and higher moisture content at field capacity (34.55%) and permanent wilting point (10.57%) were recorded in the natural forest land use system. All the six land-use systems confirmed distinct effects on soil properties as the highest superior soil properties were observed under natural forest land-use systems, followed by grassland, horticulture, agri-horticulture, and agricultural land-use systems, whereas the barren land use was showed inferior soil properties. The result of the study suggests that the incorporation of tree components on agriculture, barren, and grassland systems could decisive to improve the properties and sustainability of the soil in the study area.

Native Trees
By: Babita Rana
Page No : 221-225
Abstract
Tropical cyclones with heavy rainfall and gusty winds cause severe damage to the environment, infrastructure, and economy of the affected area. This study focuses on the impact of major cyclones on vegetation with special mention of native as well as exotic tree species, particularly in Mumbai, Maharashtra, and elucidation of cyclone resistance traits in trees. Data collected from secondary sources of information supports the evidence that tree devastation was more in exotic species than native species. In Mumbai, as per the recent Brihanmumbai Municipal Corporation census, more than half of the 29.75 lakh tree population is of exotic origin. The most susceptible trees to bear the cyclone impacts such as defoliation, snapping of stems, and uprooting were Peltoforum, Gulmohar, Thespesia, Royal palm, rain tree, which were introduced to India hundreds of years ago. The common native species mango, banyan, peepal, and neem perform fairly well which underlines the importance of planting local species in cyclone vulnerable regions. The selection of proper plant species is very crucial to minimize the damaging effects of cyclones and heavy monsoons in coastal regions.

Abstract
Tasar silk production is highly associated to natural ecosystem. Deterioration of natural ecosystem can directly affect the quality and production of tasar silk. Since regular use of chemical fertilizers reduce the fertility and total microbial biomass thus affecting soil health and productivity in tasar ecosystem. Hence, a field experiment was conducted at Central Tasar Research and Training Institute, Ranchi with an aim of improving the soil nutritional status using INM practices. The experiment was comprised 20 treatments including control which laid down in randomised block design with three replications. The soil samples were collected from each plot and analysed for different parameters. The study revealed that the pH of different experiment plots was acidic range (5.42 to 5.99). SOC was found to be higher in the treatment of 75% RDF with 25% VC + Azotobacter + PSB (1.33%) followed by 100%RDF with 2 kg/plant VC + Azotobacter + PSB (1.31%). The treatment T19 (495.5 kg ha?1 ) had recorded higher available nitrogen followed by T17 and lower in control. In case, the available phosphorus was found to be the ranges from medium to high (12.93 to 38.33 kg ha?1 ) in different treatments.

Page No : 241-248
Abstract
Soil microbial community keeps the soil healthy and fertile therefore their optimal presence is needed for sustaining the crop production to meet the basic needs of future generation. Therefore, a nutrient management trial was conducted to find out the best nutrient sources and their combinations which may improve overall soil biological health. Soil samples were collected from 0-15 cm soil depth after harvesting of maize crop during two cropping seasons. The samples were tested in laboratory following standard protocols. Application of PEC combined with 75% of NPK and bio-fertilizers inoculation is a good strategy to improve soil biological quality for sustainable agriculture.

Effect of some Micronutrients on Biomass, Latex Yield, Sugar and Chlorophylls of Euphorbia antisyphilitica
By: Ashwani Kumar , Shobha Johari
Page No : 249-256
Abstract
E. antisyphilitica is a plant of bioenergy interest. It is a woody shrub tolerant enough to dry conditions of deserts. Earlier work on this plant revealed it suitable for soils of Rajasthan. This led us to study to enhance its growth and productivity so that its suitability for biofuel production can be ascertained. One of the aspects to increase plant growth is to supplement it with proper nutrients. Hence experiments were conducted with different concentrations of micronutrients manganese, iron and molybdenum in the form of manganous sulphate, ferrous sulphate and ammonium molybdate respectively. Plants were allowed to grow for four months and then harvested and analysed for parameters biomass, hexane extractables, sugars and chlorophylls. Biomass of this plant is useful as raw wood while its latex is a promising hydrocarbon yielding source which was extracted with hexane. Results found were very positive for all the nutrients and best suitable dose were find out for each micronutrient.

By: Gopakumar Pillai , Soni Pinkesh Kumar Patel
Page No : 289-299
Abstract
Excessive concentration of heavy metals in soil affects the fertility and can have deleterious effects on plants and microorganisms thriving in the soil. With decreasing soil fertility and expanding population, the issue of sustainable food security is gaining momentum. Maize (Zea mays), one of the commercially important crops, is adversely affected by increased concentration of the heavy metals, Copper and Zinc. Plant nutrient requirements can be effectively met using bio fertilizers while reducing the dependency on chemical fertilizers. Azotobacter sp. has been proved to be an efficient bio fertilizer for a variety of crops. Two rapidly growing isolates of Azotobacter sp. (viz. Isolates A and B) were obtained from rhizospheric soil samples and their cultural, microscopic and biochemical characteristics were studied. Isolate A tolerated Cu and Zn concentrations till 0.4% while isolate B showed tolerance till 0.4% of Zn and 0.6% of Cu. Exopolysaccharide produced by isolate A showed 48% copper bio sorption. Both isolates exhibited plant growth promoting traits like IAA production, ammonia production and phosphate solubilisation. Tryptophan supplementation enhanced IAA levels. Maximum IAA production was seen with isolate A (41.49

Minimizing Allelopathic Effect of Grewia optiva on Germination and Growth of Finger Millet Using Plant Growth Promoting Rhizobacteria
By: Rakesh Singh , Yashwant Singh Tariyal , J.S. Chauhan
Page No : 301-310
Abstract
Interaction among plant species has both beneficial and harmful effect on one or both the species. It plays an imperative role in the plant growth and survival. Grewia optiva (Bhimal) is widely grown fodder tree usually grown on boundaries of crop fields. The plant is reported to have allelopathic effect on crop growth but its importance as a fodder tree cannot be ignored. The present investigation is carried out with Plant growth-promoting rhizobacteria (PGPR) strains (Pseudomonas FP-11 and Bacillus BS-10) in alleviating allelochemical (biotic) stress of Grewia optiva (Bhimal) on Finger millet. Due to presence of Grewia optiva leaf extract there was inhibition in germination, reduction in seedling fresh and dry weight, root and shoot length of finger millet in contrast to control. This inhibition was recovered with PGPR treatment of Pseudomonas FP-11 and Bacillus BS-27. The results indicated that the seeds inoculation with PGPR strains under allelochemical stress significantly improved germination, plant growth, vigour and chlorophyll contents of leaf. The root length, shoot length, seedling length, seedling fresh and dry weight were also considerably increased by seeds treatment with PGPR. The plant growth promoting rhizobacteria (PGPR) Pseudomonas FP-11 strain and Bacillus BS-10 strain in combination could alleviate allelopathic effect of Grewia optiva on finger millet. Plant growth promoting rhizobacteria (PGPR) was observed replacing the use of chemicals in agriculture, horticulture practices. This is due to the emerging demand for minimizing harmful impacts and utilization of chemical products to the growing necessity of sustainable agriculture within a holistic apparition of development and to emphasize environmental protection.

Page No : 311-314
Abstract
An experiment was conducted to study the effect of graded concentrations of Benzylaminopurine (BAP) on the growth, flowering and postharvest performance in Antirrhinum majus. Plants were raised in pot soil culture in 25 cm earthenware pots. BAP was applied as a foliar spray at 1, 5 and 25 mgl-1 concentrations. Plants were sprayed at 4, 12 and 16 weeks after transplantation. For each concentration there were five pots, besides a set of five pots each for the distilled water control and tween control. BAP at 25 mgl-1 concentration was effective in increasing plant height, fresh mass, dry mass and the number of laterals; besides resulting in the early emergence of floral buds. BAP particularly at 1 mgl-1 concentration was effective in enhancing the postharvest longevity of spikes and blooms in plain water. The results suggest that BAP as the foliar application can be effective in enhancing the pre and postharvest conditions of Antirrhinum majus.

Abstract
More than 100 countries suffer from mosquito-borne diseases which are prevalent across the world. They are the known vectors for transmission of dengue, malaria, yellow fever, filariasis, Japanese encephalitis, schistosomiasis etc. Many of the insecticides that are currently used in mosquito control have harmful effects on human health and other non-target populations, they are non-biodegradable in nature, and also have a higher rate of biomagnification in our ecosystem. The spike in insecticide resistance on a global scale is raising serious concerns. Therefore, search for natural, eco-friendly alternatives such as bio-insecticides is imperative. In this study, Larvicidal activity of the essential oil obtained from the leaves of Callistemon citrinus was tested on the Dengue vector mosquito Aedes aegypti and Chikungunya vector mosquito Culex sp. Also, the chemical composition of the essential oil was studied using GC-MS analysis. Callistemon citrinus can now be considered one of such bio-insecticides which is easily available throughout India, with many therapeutic active constituents in its essential oil and 80-100% larvicidal activity..

Abstract
The two basic approaches to manufacture NPs are the top-down and bottom-up techniques. Bottom-up approach is the alternative approach to the physical method of synthesis of NPs, which has the potential of creating less waste and hence being more economical. Nanoparticles from green synthesis have been getting an increasing advantage due to it being a cost effective and eco-friendly method for nanomaterial synthesis. The present investigation focuses on the biological synthesis, characterization of biogenic nanoparticles using extracellular filtrate of Aspergillus flavus. The characterization of synthesised silver nanoparticles has been done using techniques such as UV-Vis Spectroscopy, Fourier transform infrared (FTIR), Transmission electron microscopy (TEM) and Nanoparticle tracking analysis (NTA). The maximum peak was observed at 426 nm in UV-vis spectroscopy after every 5 minutes. In order to identify the presence of functional groups in extracellular fungal filtrate which was used for bioreduction of silver and capping of silver nanoparticles, FTIR analysis has been carried out. The spherical aggregate shaped silver nanoparticles synthesized by A. flavus ranged from 7-50 nm confirmed in TEM as well as in NTA.

Abstract
In December 2019, cases of the new coronavirus disease 2019 (COVID-19), caused by a new betacoronavirus (SARS-CoV-2), were first reported in Wuhan, China. These cases were characterized by acute pneumoniaassociated symptoms, such as fever, dry cough, chills, shortness of breath, and muscle pain. On comparing SARS-CoV-2 with SARS-CoV, significant differences were observed in the sequence of the S gene of SARSCoV-2, including three short insertions in the N-terminal domain, changes in four out of five of the crucial residues in the receptor-binding motif, and the presence of an unexpected furin cleavage site at the S1/ S2 boundary of the SARS-CoV-2 spike glycoprotein. This insertion is a novel feature that differentiates SARS-CoV-2 from SARS-CoV and several SARS-related coronaviruses (SARSr-CoVs). The SARS-CoV-2 Spike (S) protein, which is the viral protein responsible for binding the ACE2 receptor on the host cell. Prior to and after attachment, the S needs to be activated by cellular proteases (e.g. furin, TMPRSS2), triggering the virus

In-Silico Investigation of Phytochemicals as Antiageing Agents against Matrix Metalloproteinases using Molecular Docking Approach
By: Aparna Patil Kose , Shilpa N Potdar , Rupal A Mishra , Priyankal D Sharma
Page No : 421-428
Abstract
Photoageing is caused by the excitation of matrix metalloproteinases (MMPs) in the skin, which is caused by UV light causing a disruption in the balance between MMPs and inhibitors in our bodies, resulting in collagen degradation and, as a result, wrinkles development. Antioxidant phytochemicals are being researched to minimise the oxidation processes caused by photoageing. Molecular docking was used to choose the optimal phytochemical with the highest binding affinity for MMPs. The study was carried out on 100 plants effective against wrinkles out of which 30 common phytochemicals were selected showing antioxidant properties. These selected phytochemicals were further targeted against nine types of MMPs responsible for wrinkle formation using molecular docking approach. Further, protein optimization was carried out in GROMACS software to enable successful docking. The docking analysis was performed using PyRx tool and the docked structures were visualized using Discovery Studio 4.1 Visualizer. It was observed on the basis of docking score that beta carotene, rutin and luteolin phytochemicals showed highest binding affinity with the target protein (9 types of MMP). The differences in binding affinities among the proteins were discovered in this docking research various protein-ligand complexes which confirms the potential target for ageing in order to stop wrinkle development.

Understanding Physiological Basis of Senescence in Ailanthus excelsa Leaves
By: Upma Bhatt , Manish Mali , Shubhangani Sharma , Vineet Soni
Page No : 497-502
Abstract :
Leaf senescence is a major developmental event, in which leaves turns yellowing and cells passes through a series of physiological and biochemical changes, including a large metabolic shift from anabolism to catabolism, resulting in nutrition redistribution. Since dynamic protein trafficking transforms massive macromolecular complexes into transportable products through which cellular structures such as chloroplasts, nucleus and cell membrane are disintegrated. The chlorophyll fluorescence measurement can detect the physiological changes in leaves during senescence. Therefore, the OJIP-transient, leaf model and membrane model were studied to understand the photosynthetic process during senescence. The depression OJIP-transient curve and Fm shows reduction in PIcs. The increase in antenna size of LHCs ABS/RC and TR/RC increased but the phenomenological fluxes reduced, which illustrates the inhibition of electron transport chain in S5 (last stage of senescence). Although the absorption increased, but electron transport ceased so that DI/CS and DI/RC enhanced which directly influence ?Po and the leaf ultimately die.

Remodeling of Anti-oxidant Systems, Chlorophyll Contents, and Productivity in Peanut Genotypes under Waterlogging Stress
By: Upma Bhatt , Shubhangani Sharma , Vineet Soni , Jyotshana Sharma
Page No : 503-512
Abstract:
Many crops are affected by heavy rains and subsequent periods of waterlogging during the maturity phase. Therefore, waterlogging effect on antioxidative enzyme activity, chlorophyll content, lipid peroxidation, and grain yield were investigated using two contrasting genotypes of peanut: the waterlogging-tolerant line, DH-86, and the waterlogging-sensitive line, TAG-24, to better understand the biochemical and physiological mechanisms of waterlogging tolerance. Under the greenhouse environment, potted peanut plants were waterlogged up to 60 days after sowing. The activities of the antioxidant enzyme were measured by comparing the superoxide dismutase (SOD), catalase (CAT), and guaiacol peroxidase (POD) activities between waterlogging-tolerant and waterlogging-sensitive genotypes of peanut. The early stimulation of their anti-oxidant systems was responsible for variation in tolerance levels between the two genotypes. The increased, superoxide dismutase (SOD) and catalase (CAT) activities played a significant role in DH-86 in maintaining productivity and growth to recover from waterlogging stress. The susceptibility of TAG-24 was associated with lipid peroxidation damage, a reduction in chlorophyll concentration, and antioxidant enzyme activity. The photosynthate accumulation in the stems and leaves was caused by an imbalance of the source-sink relationship, and this is the principal reason for yield loss under waterlogging. TAG-24 reduced more grain yield than DH-86, most likely because more photosynthate was accumulated in the stem and leaves of TAG-24 and could not be transported to the pod efficiently. According to these findings, the better protection of DH-86 from waterlogging-induced oxidative damage is because of the maintenance of the enhanced antioxidant enzyme activity and induced grain yield capacity.

Phytochemical Screening and Antibacterial Activity of Bark Exudates in Selected Tree Species
By: K Parani , P Veera Lakshmi
Page No : 629-636
Abstract :
Plants have evolved multiple defense mechanisms against microbial pathogens and various types of environmental stress. Qualitative screening of phytochemical analysis from bark exudates of tree species (Cassia siamea, Araucaria, Artocarpus heterophyllus) were analysed. Tannins, alkaloids, steroids, saponins, reducing sugars, flavonoids, phenols, glycosides are present in aqueous and acetone extracts. But proteins and starch are present in acetone extracts of three bark samples. The maximum flavonoid content was observed in bark sample of Artocarpus heterophyllus, followed by Cassia siamea which was par with Araucaria. The highest amount of alkaloid and phenols were seen in Cassia followed by Artocarpus and Artocarpus heterophyllus. The maximum zone of inhibition were observed in aqueous and acetone extract of Cassia siamea by E. coli (20 mm) and Proteus vulgaris (18 mm). This was followed by acetone extract of Araucaria (15 mm) and Artocarpus heterophyllus (12 mm) by Proteus vulgaris. Whereas minimum zone of incubation were noted in aqueous extract of bark samples of Araucaria, Cassia (5.0 mm) and Artocarpus heterophyllus (4.0 mm) by E. coli and Bacillus subtilis. Bacterial antibiotic streptomycin which was used as positive controls were more effective compared to all the plant extracts tested against the bacterial pathogens. The aqueous extract of Cassia and Araucaria and acetone extract of Artocarpus heterophyllus showed the highest scavenging activity (Dark coloration) upon addition of FeCl3 which could be due to the high phenol content.

By: Shilpy Shakya
Page No : 651-662
Abstract
Phylum Nematoda is the most abundant group among the metazoans. Root-knot nematodes (Meloidogyne spp.) are a serious threat to agrarian plants worldwide. RKN is among the most predominant spp. which affects a variety of plants and vegetables. It is challenging for farmers to manage these nematodes. The usage of nematicides is an efficient means of management of plant-parasitic nematodes. The continuous use of chemical nematicides can cause augmentation in cases of nematode resistance. In order to fulfill the requirement of modern sustainable agriculture along with safe environment and human health, there is need to switch over to natural remedies to control RKNs. Lately, many research studies have been carried out to isolate product from natural resources and evaluate their nematicidal activity against these nematodes. The present review provides a summary of nematicidal activity of the naturally derived substances against Meloidogyne incognita over the past few years.

Abstract
The aim of the present study was to investigate the qualitative and quantitative analysis of Madhuca bourdillonii extracts and demonstrate its biological activities. The results of phytochemical analysis showed that the leaf water extract consists of more amount of total phenolics and tannins respectively of 7.4 mg of gallic acid/g and 113.28 mg%. Flavonoid content was found to be more in water extract of bark amounting to 40.73 mg of quercetin/g while the acetone extract of leaves showed more amounts of alkaloids accounting to 30.25 mg%. All the extracts of leaves and stems were evaluated for antimicrobial activity against gram-positive, gram-negative bacteria and pathogenic fungi using agar disc diffusion as well as well diffusion assays and subsequently MIC and MBC values were determined. Among all the bacteria tested, S. flexneri was most susceptible in both the assays exhibiting a zone of inhibition of 12.4 mm & 14.2 mm and 12.2 mm & 14.6 mm respectively for water and acetone extracts of bark. The IC50 values were found to be in the range of 4.52 - 31.34 mg/ml for all the tested bacteria. Among the fungal species tested, C. albicans was found to be susceptible with a zone of inhibition of 7.63 mm for bark water extract in disc diffusion assay and 12.36 mm with leaf ethanol extract in well diffusion assay. The IC50 values were found to be 12.37 - 31.65 mg/ml for C. albicans and F. oxysporium. The results show that Madhuca bourdillonii has excellent anti-bacterial properties which might help the development of novel lead drugs for treatment of various diseases.

Exploration of Endophytes from Azadirachta indica for Antifungal Activity
By: Seemadevi Suresh Kadam , Shivangi Shivraj Kanase
Page No : 683-690
Abstract
Endophytes are the plant associated microbes that live within the living tissues of their host plants without causing any harm to them. Bioprospecting of endophytes from understudied ecosystems is a promising source for extracting novel antifungal metabolites useful for pharmaceutical/cosmetic purposes. The aim of present study was to explore endophytes for antifungal activity against Aspergillus species and Candida species. To achieve this, endophytes were isolated from Azadirachta indica leaves. Cross streak and agar overlay methods were followed for screening for antifungal activity. Secondary antifungal activity was carried out for positive antifungal isolates using agar well diffusion method. In present study, twenty four fungal endophytes and fourteen bacterial endophytes were isolated from leaves of Azadirachta indica by optimizing suitable surface sterilization protocol. Out of these six bacterial isolates were found to produce antifungal compound against Candida albicans and two isolates were found to be inhibitory towards Aspergillus species. In secondary antifungal assay, one bacterial isolate showed anticandida activity. The results of this study suggest that these endophytes producing antifungal compounds may have medicinal value. Further studies related to characterization and identification of these compounds may lead to the development of novel products beneficial to human kind.

Abstract
Fruits and vegetables are integral part of our day to day. They are the main source of food for the living system. Large amount of agro-waste generated from food industries and kitchen pertaining to biggest nutritional loss, environmental problems and economical implications. Even though pomace, peels, rind and seeds are considered a waste part of plant they are still rich source of valuable compounds like polyphenols, oils, enzymes, vitamins, fiber, etc. which is just adjunct to its different uses. Present study conducted on waste pumpkin peel. HPTLC fingerprint profile of pumpkin peel methanol extract was performed using HPTLC plate of silica gel 60 F254 as the stationary phase and Toluene: Chloroform: Ethanol (4:4:1 V/V/V) as the mobile phase. After development chromatogram was scanned at 254 nm and 366 nm by densitometric scanner. Anisaldehyde in sulphuric acid is used as a detecting reagent which gives pink-violet and/or giving blue coloration after derivatization of plate. Further HPTLC-MS analysis gives the confirmation to detected terpenoids. Therefore, this waste peel part of the pumpkin can be used in an ingenious way by further purification, isolation and characterization.

A Review of SAR Image Processing for Mangrove above Ground Biomass Estimation
By: Archana Singh , Seema Mahajan
Page No : 779-789
Abstract
Mangrove biomass monitoring has become critical today, as it aids in measuring the amount of carbon that will be contained in these forests in the future. Remote sensing is possibly the solution for estimating AGB on a large scale. It allows biomass assessments over large areas, providing a spatially comprehensive measure of forest biomass variance in a relatively short time and at a low cost. Because of the penetration capability of radar remote sensors, the high-frequency L-band and P-band can be used to measure aboveground biomass effectively. The study emphasizes the importance of Synthetic Aperture Radar imaging and the correlation between backscatter reflectance of remotely sensed data and live biomass over a given area. Despite many studies on the use of machine learning algorithms for biomass estimation, no single model fits all problems. Furthermore, finding the best machine learning model is critical for advancing global expertise in the field of mangrove forest management. The hybrid models such as extreme gradient boosting regression (XGBR) and extreme Gradient Boosting (XBoost) are also used along with regression models linear regression, multilayer perceptron (MLP), and machine learning approaches like support vector Machine (SVM), random and random forest (RF) is used in mangrove studies. In comparison to the allometric equations based on ground truth data, remote sensing methods are coming up as an effective tool for AGB estimation of mangroves. This vision survey focuses on SAR radar remote sensing-based studies in mangrove forest biomass estimation and the limitation of SAR imaging in AGB estimation.

Heterosis and Inbreeding Depression Analysis in Bitter Gourd (Momordica charantia L.)
By: D R Bhardwaj , Akhilesh Kumar Singh
Page No : 791-800
Abstract
Experiment with 45 hybrids (F1s) under 10 x 10 diallel analysis was carried out to estimate the extent of heterosis over mid and better parents for yield and its contributing traits in bitter gourd. The inbreeding depression for various traits was also worked out. Analysis of variance indicated highly significant differences for almost all characters except plant height suggesting presence of wide genetic variability. The heterosis exhibited for fruit characters and fruit yield was mostly positive. Ten cross combinations (DVBTG-1 x VRBT-6, VRBT-94 x VRBT-39, VRBT-94 x VRBT-49, VRBT-94 x VRBT-103, VRBT-94 x VRBT-63, VRBT-94 x VRBT-32, VRBT-94 x VRBT-6, VRBT-41 x VRBT-6, VRBT-103 x VRBT-6 and VRBT-63 x VRBT-32) which recorded high heterosis for yield and also expressed high heterosis for yield components, indicating the additive or synergistic effect on the fruit yield. These cross combinations can be utilized for commercial exploitation and determining the strategies for future in bitter gourd hybrid development. The inbreeding depression results due to fixation of unfavorable recessive genes in F2 . In the present results high inbreeding depression indicates the presence of non-additive gene action (dominance and epistasis) for the traits like first male and female flower anthesis, fruit weight, plant height and number of fruits/plant. The minimum inbreeding depression was observed in cross VRBT-32 x VRBT-6 and VRBT-94 x VRBT-49.

In the present study, a detailed karyotype analysis has been developed for Strychnos dalzellii C. B. Cl. and Strychnos minor Dennst. - the two prosperously growing, ethnomedicinally well-known climbers of the family Loganiaceae. The chromosome number of S. dalzellii and S. minor was found to be 2n=38 and 2n=40 and the karyotypic formula is A12 + B16 + C10 = 2n = 38 and A6 + B14 + C20 = 2n= 40 is respectively. On the basis of position of centromere, the formula can be written as, m34 + sm3 + st1 = 2n= 38 and m38+ sm2 = 2n=40 for Strychnos dalzellii C. B. Cl. and Strychnos minor Dennst. respectively. This pool of genetic variation needs to be measured and recorded to increase the awareness of the importance in adopting conservation and sustainable utilization.

A Study on the Micromorphological and Beaded Stamen of Three Species of Pogostemon Desf. (Lamiaceae Linn.) in Assam, India
By: Chayanika Bordoloi , G. C. Sarma
Page No : 827-834
Abstract
The morphology and distribution of the trichomes on the aerial parts and the feature of moniliform hairs in the stamen of Pogostemon Desf. of Assam, India were studied to understand the significance of these characters for taxonomic purposes. The three species studied are Pogostemon brachystachyus Benth., Pogostemon quadrifolius (Benth.) F. Muell, and Pogostemon strigosus (Benth.) These species of Pogostemon Desf. were mostly terrestrial while few species growing in marshy areas also. The trichomes on leaves and the moniliform hairs or beaded stamen of all the three species were investigated by both Light microscope and Scanning Electron Microscopy (SEM). The stamen with hairs was considered a unique feature that makes it a distinct genus in the family Lamiaceae, and also helps in the identification. The main types of trichomes that were distinctively observed on the leaf surfaces are, simple non-glandular unicellular and multicellular trichomes and peltate, glandular trichomes. Moniliform hairs and trichome morphology of Pogostemon brachystachyus, Pogostemon quadrifolius, and Pogostemon strigosus have not been studied previously in the study area and such investigations on Pogostemon in the study area are rather limited

By: Sandeep Chand Upadhyay , A. B. Bajpai , Pardip Kumar
Page No : 847-859
Abstract
In textile sector uses a huge volume of water and chemicals, including inorganic compounds, polymers, and organic products. Textiles effluents including different types of dyes like acidic, reactive, basic, disperse, azo, diazo, anthraquinone and metal-complex dye. Textile effluents create chronic ecological problems due to their toxicity, pernicious and carcinogenic characters and, at present, purification process of textile effluents is a critical problem for society. Biosorption process through water hyacinth biomass as a fructuous and inexpensive process for the expel of dyes from textile industrial colorants. In the present study, biosorption of basic fuchsin dye was carried out using different doses of the dried and powdered biomass of water hyacinth. The dose of plant biomass (50mg to 400mg) observed high percentage of adsorption at 20 ppm dye concentration. The results of Freundlich adsorption isotherm showed a better biosorption than Langmuir adsorption model. FTIR spectra of the unloaded and dye loaded biomass showed the change in the surface chemistry of the biosorbent and predicted the role of C=N (Very StrongVS), C=S (Strong- S), CH2 (Strong-S), CH=CH (Strong- S) groups in the removal of basic fuchsin dye from the aqueous solutions.

Page No : 861-874
Abstract
Excessive use of pesticides has been known to create hazardous to the environment, including affecting soil fertility may also impart toxicity in living organisms. Presently, there have been biological approaches implicated to reduce or eradicate pesticides through physical and chemical methods are inefficient. Microorganisms have a potential to mineralize carbendazim with the help of nutrient minimal mineral salt (MMS) medium and soil. Microorganisms were developed resistant against carbendazim MMS medium and they were identified based on its colony morphological characters and 16s rDNA gene sequencing. A total of four bacteria were identified and evaluated for the degradation of Carbendazim. Initially, all bacteria were grown in MMS media supplemented with fungicide to acclimatized and use Carbendazim as sole source of Carbon. The chemical oxygen demand (COD) was carried out and removal of Carbendazim were recorded after 3, 7, 11 and 14 days of incubation period. Bioremediation of carbendazim was analysed in three defined concentration as 100 mg/l, 200 mg/l, and 300 mg/l in

Association of Pseudomonas syringae pv. apii with the Seed of Ajwain (Trachyspermum ammi L.)
By: Nanda Ram , Vishal Sharma , Indu Singh Sankhla , Kailash Agrawal
Page No : 883-892
Abstract
Present study aimed to isolate, identify and characterize the bacterial pathogens associated with ajwain seeds using biochemical and molecular methods. One hundred thirty-nine seed samples of ajwain were collected from various districts of Rajasthan. Twenty-four bacterial isolates were isolated and purified from collected seed samples. All strains were characterised for their biochemical activity. All isolates were tested for genetic diversity by using amplified rDNA restriction analysis (ARDRA). Selective strains were subjected for 16S rDNA sequencing and molecular phylogeny study. Most strains were positive for levan production, tobacco hypersensitivity, gelatine liquefaction and aesculin hydrolysis but showed negative reactions for activities of oxidase, tartrate utilisation, potato soft rot, tyrosinase and arginine dihydrolase. These isolates were distinguished into three groups based on the ARDRA pattern. Selected isolates (KANRJ 1507, KANRJ 1562 and KANRJ 1637) were subjected for 16S rRNA gene sequencing. In phylogenetic analysis all three isolates showed 99.85% similarities to each other. In addition, KANRJ 1507 showed 99.93% sequence similarity to P. syringae pv. apii strain BS426 while KANRJ 1562 and KANRJ 1637 showed 99.85% sequence similarity with P. syringae pv. apii strain BS426 isolated from Petroselinum crispum in California, USA. It was also observed that KANRJ 1507 and other two strains (KANRJ 1562 and 1637) showed 99.61% and 99.54% sequence similarities respectively with P. syringae pv. maculicola isolated from radish in the USA.

Page No : 907-918
Abstract
Foxtail millet (Setaria italica) is one of the least studied crops in terms of genetic resource characterization and genetic enhancement while compare to cereals. Hundred foxtail millet lines representing the national collection were evaluated at Medziphema, Nagaland University in Summer-2022 for polygenic trait evaluation and data subjected to genetic diversity analyses. Hundred foxtail millet genetic resources were divided into ten clusters by non-hierarchical cluster analysis (k-mean) was used and Elbow method was used to find out the optimum number of clusters. Genotypes were grouped into different cluster viz. Cluster I (6), Cluster II (9), Cluster III (12), Cluster IV (4), Cluster V (9), Cluster VI (8), Cluster VII (14), Cluster VIII (17), Cluster IX (17) and Cluster X (4). Cluster X had four accessions which are characterized by desired mean values and the genotypes belongs to these clusters can be utilized for the future breeding programs. The first five PCA components generated up to 82.43 percent of the diversity across genotypes tested for various agro-morphological variables. The first principal component explained 37.50 percent while, the second, third, fourth and five principal component exhibited 16.53 percent, 10.91 percent, 9.53 percent and 7.49 percent variability respectively, among the germplasm lines for the traits under study. Genotypes G2, G5, G10, G27 have low values for days to 50% flowering, days to maturity, plant height and high values for panicle length, flag leaf length and peduncle length, biological yield, fodder yield and grain yield per plant so that these genotypes can be used for general cultivation under Nagaland conditions and these materials could be used in further breeding programme.

Abstract
Distyly in Neanotis indica (DC.) W.H Lewis., (Rubiaceae) a distyous species with Pin flowers (long style and inserted stamens in the corolla tube ) and thrum (flowers with exerted anthers and inserted style) accompanied by self incompatibility in both forms but cross compatibility is described for the first time. The population composition shows panmixis at several locations at Sims Parks, Coonor, Ootacamund, Tamilnadu, India. Distyly is a reciprocal mechanical arrangement of style and stamen heights accompanied by an array of contrasting differences in pollen and stigma papillae dimorphism accompanied by physiological incompatibility. The pin and thrum morphs are self incompatible but cross compatible in nature. Based on the data it is suggested that the S- supergene of heterostyly controls the genetic architecture in the species.

Emerging Sugarcane Abiotic Disorders under Subtropical Conditions: An Appraisal
By: Gulzar S Sanghera
Page No : 81-96
Abstract
Sugarcane (Saccharum spp.) is an important agro industrial cash crop, providing raw material for different sugar industries and plays crucial role in the economy of several countries. It requires optimum climatic conditions for economic crop production and causes reduced cane and sugar yields otherwise. Climate change especially temperature extremes either low or high causes abiotic disorders like cold / banded chlorosis and sunburn during initial and mid season crop establishment led to yield reduction in sugarcane by affecting its physiology, biochemistry and quality leading to poor agronomic produce in subtropical conditions. Low temperature during winter (December-January) for autumn planting and high temperature during summer (May-June) for spring planting also affects the germination percentage, seedling establishment and ratoonability of early harvested (Nov-Dec) crop. Several breeding and genomics based studies have been conducted to improve the sugarcane production under different stresses in this crop in many areas of the world. The studies on abiotic disorders caused by high and low temperature extremities and their mitigation strategies are scanty. An attempt has been made in this appraisal report to explore sugarcane clones/ cultivars that contribute to adaptation in era of climate change by discovering and introducing desirable genes for agronomic traits using basic breeding methodologies, physiological approaches and new technologies of molecular biology that can mitigate the negative effect of extreme temperature and improve sugarcane yields, productivity and sustainability.

The Uncultivated and Wild Leafy Vegetable Consumption in Devarakonda
By: Rama Raju Cherkupally
Page No : 113-119
Abstract
Many uncultivated and wild leafy vegetables have been utilized as a food and as folklore medicine since time immemorial. Such vegetables have been part and parcel of the food dishes, especially to the ancient rural and semi-urban dwellers. Despite much nutritional value, researchers and agricultural scientists have given less attention to such vegetables.
A total of 38 plant species belonging to 20 families was recorded after conducting surveys. Family Amaranthaceae recorded the highest number of species (10 species) followed by Caesalpinaceae (5 species), Lamiaceae, Apiaceae, Malvaceae, Convolvulaceae, Aizoaceae (2 species each) and remaining all one species each. It is observed that tribal communities not only used for self-consumption, but they also tried to sell by tribal women seasonally in weekly markets to earn income. Uncultivated leafy vegetables like chenchali, bacchali, puntikura, payalkura, ponagantikura, chintachiguru and tootikura are also sold in towns, as they are preferred by people in towns, because they were liked by urban dwellers, and were recognized as well for health. For several reasons, people no longer eat wild seasonal uncultivated greens as in former years, which is the reason for low consumption in this population.

Abstract
Zea mays L., Maize, a crop cultivated globally, is used as food, feed, and used to manufacture diversified industrial products. It has become necessary to employ new methods for high maize production and increase its quality potential in response to the upsurge in the human population and climate change. The maize breeding procedures have now incorporated important components like genome-wide selection and high-density genotyping to ease the functional analysis of its genome. Every growth stage displays tremendous genetic diversity in maize, which can be studied through advanced phenotyping and genotyping technologies wherein physiological, genetic, and molecular characteristics can be understood and manipulated. Such studies will undoubtedly lead to an increase in maize crop improvement. This review highlights the developments in the characterization of maize through genotyping and phenotyping with the advent of novel technologies.

Global Warming and Third Generation Algal Biofuels : A Review.
By: Ashwani Kumar , Shobha Johari , Praksha Verma
Page No : 155-165
Abstract
Increasing populations and industrialization is causing enhanced production of greenhouse gases (GHG) resulting in global warming. Climate change poses unprecedented threats to human health by impacts on food and water security, heat waves and droughts, violent storms, infectious disease, and rising sea levels. Renewable sources of energy provide and answer to greenhouse gas mitigation as they are carbon neutral or nearly so. However, first generation biofuels require land and water for cultivation and second generation biofuels from lignocellulose waste need technology up gradation to make them commercially viable on large scale. Third generation biofuels from algae are very promising as they can be grown in fresh water, waste water and sea water in ponds and also in closed systems under controlled conditions. The extraction process from Algae is less complicated and more economically viable. In our review we wish to present state of art information on technological advances in biofuel production from algal biofuels for greenhouse gas mitigation.

Pollen Morphology And Viability Analyses in Clematis terniflora DC
By: Rajeswari S. , Sumitha V. R
Page No : 189-192
Abstract
Clematis terniflora a highly domesticated ornamental plant, grown mainly for its fragrance, this flowers is propagated entirely by vegetative means. Sexual reproduction is rarely observed, being either pollen sterile or seed sterile. Hence propagation is mainly through stem cuttings. The present study focuses on the palynological investigation involving pollen morphological and viability studies. The electron microscopic study revealed prolate-spheroidal pollen with tricolpate aperture. Viability studies carried out using in vitro and in vivo methods revealed lower germination rate with an estimated rate of about 78.8% pollen sterility. Cross-pollination was better compared to self-pollination. Pollen germination was not observed in self-pollinated flowers. The present study revealed limited pollination and fertilization thereby reducing its natural regeneration and population.

Methyl Jasmonate: A Potent Player in Salinity Stress
By: A. Hemantaranjan , Shivani Lalotra , Rekha Sodani
Page No : 219-224
Abstract
Salinity stress an atrocious stress customary in various parts of India and across world is one of the major reasons for subordinating the yield of several crops. It leads to oxidative stress and nutrient unavailability which poses serious threats to soil fertility and soil structure. The excessive amount of soluble salts in soils is major cause of desertification in various countries. Current agriculture scenario and the climatic conditions are expected to worsen abiotic factors globally and ultimately curbing the yield potential of various crops. Therefore, certain biotechnological or plant physiological strategies or tools needed to be supplement for target crops to specific environments. Such tools are the exploitation of phytohormones in agriculture sectors. Among these, Methyljasmonate is an important phytohormones used incessantly in improving the yield per unit area of crops known to alleviate various stresses and to improve the quality and quantity of crops by activating the antioxidant machinery in plants and up- regulating the stress related genes. These oxylipins plays vigorous role in growth and development, senescence, flower nectar secretion, G-protein signaling, in plants. Besides its remarkable role in biotic stresses like salinity, drought, temperature extremes it has also foremost role in activation of defensive secondary metabolites in biotic stresses like pathogen attack.

An Eco-friendly Aerobic rice (An Efficient Water Management Strategy for Rice Production)
By: Harvinder Kaur Sidhu
Page No : 249-262
Abstract
Over the centuries, lowland rice has proven to be a remarkably sustainable system for rice production mostly because of its luxurious water availability. But the present day water crisis threatens the sustainability of lowland rice production and necessitates the adoption of water saving irrigation technologies. Technologies like saturated soil culture and alternate wetting and drying are receiving renewed attention by researchers. These technologies reduce water inputs only at the expense of yield. Aerobic rice technology is better remedy for future climate change under drought condition with lesser green house gas (GHG) emission. Selection of good aerobic rice variety with desired physiological attributes gives better performance. Proper cultural practices and regular care on crop should be recommended for on par yield with low land rice. Weed free aerobic environment is must for better performance and improper weed management leads more manpower usage. Yield penalty, yield stability of aerobic rice have to be considered for adoption.

Nutrients and isotopic composition in Rhizophoraceae mangroves of Kochi, South west coast of India
By: Nebula Murukesh , Chandramohanakumar N
Page No : 331-344
Abstract
The present study investigates the macronutrient and micronutrient elemental composition and isotopic composition in five Rhizophoraceae mangroves plants widely distributed along Kerala coast in order to verify the response and variations in these plants towards different nutrient elements and classify them accordingly. The lower C/N values of the leaves suggest that the leaves have high nutrient quality than bark. Bruguiera showing highest values of Na/K can be thus concluded to be the plants with least salt excluding capacity. The iron rich mangrove plant was found to be B. gymnorhiza. Zinc content was found to be highest in K. candel. Amount of Pb in all the leaf and bark samples under study in this research were found to be below the recommended levels while cadmium was found to be accumulated in the leaves and bark of R. apiculata as well as in the leaves of B. cylindrica and K. candel. The stable carbon isotope composition of leaves of the Rhizophoraceae mangrove under the present investigation matches well with the already established values of ?13C for C3 plants and the present nitrogen stable isotope results fall within the range of plants that obtain inorganic nitrogen directly from seawater.

Antimicrobial Activity of the Leaf Extracts of Strelitzia reginae
By: Ramesh L Londonkar , Rajani KS
Page No : 381-397
Abstract
The antimicrobial activity of the leaf extract of Strelitzia reginae was studied on six Gram-positive and six Gram-negative bacteria. The leaf extracts of Strelitzia reginae were obtained by the Soxhlet extraction process using the following solvents, petroleum ether, chloroform, methanol, and distilled water in the increasing order of their polarity.
In order to locate the maximum and efficient antimicrobial activity among the leaf extracts of Strelitzia reginae, three sets of experiments were conducted.
Firstly, the four extracts of leaves of Strelitzia reginae namely petroleum ether extract (PE), methanol extract (ME), chloroform extract (CE), and aqueous extract (AE) were tested for their antimicrobial activity with two bacterial species. A Gram-positive bacterium, Staphylococcus aureus ATCC 6538, and a Gram-negative bacterium Klebsiella pneumoniae ATCC 13882. The antimicrobial activity was determined using the well diffusion method. Among the test samples, samples AE, CE, ME, and PE showed antibacterial activity against Klebsiella pneumoniae; samples AE, CE, and PE showed antibacterial activity against Staphylococcus aureus. Highest activity was shown by sample CE against Staphylococcus aureus (12 mm). Samples ME and PE showed highest activity against Klebsiella pneumoniae (10 mm).
Secondly, since the highest antimicrobial activity was located with CE and ME, six Gram-positive bacteria namely; Staphylococcus aureus ATCC 6538, Mycobacterium tuberculosis MTCC 25177, Streptococcus mutans ATCC 25175, Staphylococcus epidermis ATCC 35984, Enterococcus faecalis ATCC 29212, Lactobacillus acidophilus ATCC 314, and six Gram-negative bacteria namely; Klebsiella pneumoniae ATCC 13882, Pseudomonas aeruginosa ATCC 7903, Proteus mirabilis ATCC 7002, Enterobacter aerogenes ATCC 13048, Salmonella typhimurium ATCC 733, Escherichia coli ATCC 8739 have been tested with CE and ME of Strelitzia reginae respectively. Among the test samples, sample CE showed antibacterial activity against Staphylococcus aureus, Mycobacterium tuberculosis, Streptococcus mutans, and sample ME showed antibacterial activity against Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterobacter aerogenes at 4 mg concentration per well.
Thirdly, since CE showed maximum antibacterial activity with maximum zone of inhibition values against both Gram-positive and Gram-negative bacteria, minimum inhibitory concentration test was conducted on the micro-organisms that showed zones of inhibition. The sample-CE showed 50% inhibition at 1.25mg against Staphylococcus aureus, 0.625mg against Mycobacterium tuberculosis, 1.25mg against Streptococcus mutans, 2.5mg against Escherichia coli, 1.25mg against Klebsiella pneumoniae, 2.5mg against Pseudomonas aeruginosa, 2.5mg against Proteus mirabilis, 2.5mg against Enterobacter aerogenes in micro broth dilution technique.

The potential roles of novel phytohormones like Jasmonates had been considered so far and copious investigation is going on in finding the impending role of jasmonates in abiotic and biotic stresses. In the list of known classical plant hormones, jasmonates, [jasmonic acid and its methyl ester (methyl jasmonates)] shown as potential tool in enhancing tolerance of plants against various physiological processes. These oxidized lipids (oxylipins) mainly derived from ?linolenic acids (?-LAs), plays an active role in senescence, flower nectar secretion, G-protein signaling, and development in plants. Exogenous application of jasmonates on different plant parts have proved effective in improving plant abiotic stress tolerance particularly salinity, drought, and temperature (low/high) conditions and also in biotic stress tolerance like pathogen attack or wounding by production of defensive secondary metabolites, through the stimulation of phenyl-propanoid metabolism resulted from accumulation of JA in plant cells or tissues. Based on this prolific role of jasmonates and its derivatives in different fields of biological sciences these phytohormones have opened new vistas and increasing interest in future Agricultural, Biotechnological and Physiological researches.

Ecotoxicity of a Pesticide Dichlorvos on a Biofertilizer Anabaena oryzae
By: Saumya Snehee , D.D. Pandey
Page No : 51-56
Abstract
Anabaena oryzae, an autotrophic nitrogen fixing cyanobacterium, exhibited strong potentiality to serve as bio-N-fertilizer in place of synthetic fertilizer, urea. But the cyanobacterium was very sensitive to an organophosphate pesticide dichlorvos, frequently employed in the paddy fields of Nalanda for pest control. Dichlorvos inhibited growth of the cyanobacterium above concentration of 5ppm, while the 75 and 100ppm doses were completely lethal for the microorganism. The lethal doses caused massive lysis of the cyanobacterial cells. However, the metabolic activities like photosynthesis, respiration or nitrogen fixation was not influenced by dichlorvos.

By: M. Sujatha , K.T. Ramya , T. Papi Reddy
Page No : 89-97
Abstract:
Prebreeding programmes facilitate generation of novel populations essential for crop improvement programme besides identification of heterotic patterns needed for development of hybrid populations. One of the key factors which contributed to successful adoption of prebreeding approach is utilization of landrace germplasms, unadapted exotic lines, and wild relatives from the primary, secondary and tertiary genepools. Prebreeding and cultivar development are essential interdependent activities and are the major controlling factors that determine the pace at which cultivars are released consistently to the farmers. This chapter deals with attempts made employing certain prebreeding methods and strategies followed to transfer key genes from wild genepools to cultivated oilseed crops.

Genetic Variability, Correlation and Path Coefficient Studies in Pea (Pisum sativum L.) Genotypes under Foothill Condition of Nagaland
By: Kisemsala Longkumer , H.P. Chaturvedi
Page No : 125-130
Abstract :
Analysis of variance revealed significant variation among the genotypes for all the character studied. The studies also showed that the PCV were higher than the GCV for all the characters studied indicating the role of environmental variance in the total variance. High heritability coupled with high genetic advance as percent of mean was observed in days to 50% flowering and diameter of pods indicating that these characters are controlled by additive gene effect and phenotypic selection of these characters would be effective for further breeding purpose. Correlation analysis revealed significant positive association with seeds per pod and shelling percentage. The path analysis revealed that seeds per pod contributed maximum positive direct effect on pod yield per plant and also exhibited positive correlation with yield. This shows true relationship between these traits and selection emphasis should be given on seeds per pod.

Morpho-cytology and its impact on seed viability in Vitex negundo (Linn) an unexplored wild shrub from Jammu division, J&K (India)
By: Nisha Bhagat , Mamata Jamwal , Arun Kumar Khajuria , Rupali Nanda
Page No : 139-149
Abstract :
Vitex negundo Linn. (Lamiaceae) is a wild aromatic shrub of immense medicinal utility. It is largely used to cure various fungal diseases, inflammations, hepato-protective and antioxidant disorders. Bearing in mind its worldwide distribution, medicinal potentialities and an unexplored position in J&K (India), present work embodying morpho-cytological details and its influence on pollen and seed viability was carried out on plant populations identified and localized from five districts of Jammu division of J&K, India (area of study). Morphological studies in these populations revealed non-significant difference between the mean of various parameters studied, whereas cytological studies affirms a stable diploid chromosome number of 2n=34. Despite of several abnormalities in the form univalents, multivalent (quadrivalents and hexavalents), chromosome stickiness and Bchromosomes, regular segregation during anaphase results in high pollen viability ranging from 81% to 95.7% in the plant species. From above observations it can thus be concluded that meiotic system has no role in determining the seed viability of the species. Various other factors such as physiological (hard seed coat) or maternal (role of genes) may be responsible for poor propagation of the species in natural conditions, which further needs detailed probing.

Isolation and Characterization of Lectins from Dolichos lablab and Lagenaria siceraria
By: Prachi Nikam , Kanchan Chitnis
Page No : 151-156
Abstract:
Lectins are proteins found in plants and different organisms. They possess the ability to bind to specific carbohydrate and can agglutinate erythrocytes. In the present study, two Indian varieties of plants namely, Field Beans (Dolichos lablab) and Bottle Gourd (Lagenaria siceraria) were used to extract and characterize lectins for their haemagglutination activity against the human ABO blood group antigens. Boiled and unboiled seeds and pulp were used. Crude extracts were prepared using 0.15M NaCl solution and were estimated for proteins by Biuret method. Salting out fractions were obtained using Ammonium sulphate and proteins from these fractions were estimated by Folin Lowry method. Field beans had higher protein content (4.76mg/ml) than Bottle Gourd (1.05 mg/ml) and there was a decrease in protein content after boiling(2.12 mg/ml, and 0.58 mg/ml respectively). The crude extract and fractions were assayed for qualitative and quantitative hemagglutination activity and sugar specificity. Field Beans extract of unboiled seeds showed agglutination with human blood group A and B and showed a very high intensity with Hemagglutination Units (HU) of 1024. Field Beans extract showed agglutination with blood group A even after boiling, although the intensity was lesser than unboiled extract. Bottle Gourd extracts did not show any agglutination activity. Positive haemagglutination for Blood Group A and B was observed exclusively in Dolichos lablab fraction: 0-25%. The other fractions did not show any haemagglutination activity indicating that lectin was extracted in the 0-25% fraction. This fraction was electrophoresed by Native PAGE. A single band of approximately 66.5kDa was observed on the gel. Lectins of Dolichos lablab were found to bespecific for sugars- Glucose, Galactose and Lactose. From this study, it was concluded that boiling decreased the lectin activity but did not completely alleviate it. This is contrary to the belief that boiling leads to complete removal of lectin activity. Agglutination activity of Dolichos lablab lectin can be used in blood typing and also in differentiation of normal and aberrant cells. Lectins can help in early detection of changes in cell topology, especially in cancer. The lectin from Dolichos lablab has shown to be very potent, with very high agglutination titreunits. Thus, it shows great promise in detecting very subtle changes in glyco-topology of aberrant cells.

Phytochemical and antioxidant attributes of Rhus chinensis Mill., an edible wild fruit from Sikkim Himalaya
By: Dhani Raj Chhetri , Justina Mahanta , Arun Chettri , Aditya Pradhan
Page No : 157-166
Abstract:
Rhus chinensis Mill. is a wild medicinal plant found in Sikkim Himalaya, which yields edible fruits. The juice concentrate from the fruits is used traditionally for the cure of various gastric disorders. The present study was carried out to analyze the phytochemical and nutraceutical constituents of the fruits of R. chinensis and to see whether the antioxidant properties are related to these constituents. Proximate and nutritional analyses were performed by the AOAC methods. Lycopene and ?carotene were estimated by the method of Nagata and Yamashita. Total phenolics was calculated in terms of gallic acid equivalents and total flavonoids as well as flavonol contents were calculated as rutin equivalents using standard methods. Antioxidant capacity was determined by DPPH, ABTS, Hydrogen peroxide scavenging activity and total antioxidant activity. Mineral contents were determined using inductively coupled plasma optical emission spectrometer (ICP-OES). The findings reveal the presence of a very high content of phenolics, flavonoids, vitamin C and dietary fibres in addition to the appreciable amounts of lipids, total carbohydrates and calorific value. The fruit extracts prepared in water, ethyl acetate and aqueous methanol exhibited strong antioxidant activity in different assays. Solvent and assay specific variations were evident. The fruits also contained high levels of micro- and macro elements. The study supports the medicinal and nutritional value of Rhus chinensis. The medicinal properties exhibited by the fruit extracts may be due to its strong antioxidant properties and the antioxidant properties in turn may be due to the presence of appreciable level of secondary metabolites.

Variability and character association studies in Black gram (Vigna mungo L. Hepper)
By: Thokala Surekha , Pankaj Shah , Preeti Kumari
Page No : 177-183
Abstract:
Present study was conducted to assess the magnitude of variability and character association for grain yield and contributing traits in black gram genotypes at the experimental farm of School of Agricultural Sciences and Rural Development, Nagaland University Medziphema campus representing foot hill condition of Nagaland. Pulses being the major source of protein of vegetarian population of India are high in demand. So this study aimed to identify genotypes of black gram which have a broad spectrum of variability and traits having positive association with seed yield for indirect selection. Studies were done in twenty-six genotypes of black gram for twelve traits. The results indicated that PCV was higher than the GCV for almost of all the traits. High heritability was observed for seed yield per plant, number of pods per cluster and number of clusters per plant suggesting that these traits are primarily under genetic control. Correlation studies revealed a significant and positive association of seed yield per plant with number of pods per cluster and number of clusters per plant at phenotypic level. In general, the magnitude of genotypic correlation was higher than the phenotypic correlation. This suggested a strong genetic association between the traits and the phenotypic expression was suppressed due to environmental influence. Based on variability and association studies, number of seeds per pod and number of pods per cluster were found to be the major contributing traits for yield. Therefore, these traits can be considered as selection criteria for selection and for discrimination of outstanding black gram genotypes.

Reducing the Use of Fungicides Sprays with Natural Compounds and Biocontrol Agents for Late Blight Management: A Review
By: Abdul Majeed , Zahir Muhammad , Rehmanullah , Naila Inayat , Saira Siyar , Shabir Hussain Wani
Page No : 185-196
Abstract:
Late blight of potato, a pathogenic disease of members of Solanaceae caused by Phytophthora infestans, has drastic effects on yield and quality of potato and tomato. The disease is generally managed by exhaustive applications of different fungicides, which manifests an efficient mechanism to minimize yield losses; however, the evolution of new pathogenic strains of P. infestans with unusual virulence potentials and fungicide resistance and environmental problems caused by fungicide use has drawn much attention in recent times to revise the disease control methods. Addressing the public and scholarly concerns over the frequent uses of late blight fungicides, novel, eco-friendly and safe, natural compounds are needed to be used as fungicides alternative for controlling late blight disease. This article reviews the potential role and efficacy of some natural compounds as alternative agents to commonly used fungicides. The discussion particularly focuses on plant and compost extracts, essential oils and biological antagonists as a whole or their products as possible substitutes or analogues to synthetic fungicides.

Callus Induction, Proliferation, Somatic Embryogenesis and Plant Regeneration in Gladiolus Communis L.
By: Peer Saffeullah , Neelofer Nabi
Page No : 205-209
Abstract:
Gladiolus communis L. is an ornamental herb belonging to family Iridaceae, which is widely used in cut-flower business. But multiplication rate of Gladiolus is very slow in natural conditions and is damaged by Fusarium corm rot. So, this study was aimed to design an efficient callus induction and plant regeneration protocol for Gladiolus. Callus was induced using bulb explants of Gladiolus when incubated on MS medium supplied with various concentrations of 2,4-D. Maximum callus proliferation was obtained in 0.5 mgL-1 2,4-D amended medium, but the proportion of callus proliferation showed a decreasing tendency at higher concentration (1-2 mgL-1 2,4-D). At lower concentrations (0.5 mgL-1 2, 4-D), the maximum callus proliferation was observed (1.10 g), while at 1.0 mgL-1the callus biomass was 0.9 g in 4 weeks after inoculating the initial mass of 0.3g of callus . So, high concentrations of 2, 4-D decreased the rate of callus formation. Auxins particularly, 2,4-D (1-2 mgL-1) is crucial for initiation of embryogenicalli with maximum embryogenic induction frequency of 70% in 0.5 mgL-1 2,4-D supplemented MS medium. The medium when supplemented with BAP either alone or in combination with NAA results in development of somatic embryos with globular and other stages. The maximum no. of embryos was observed in 0.5 mgL-1BAP and 0.5 mgL-1 NAA amended medium. Plants were regenerated on the BAP and NAA supplemented medium with maximum conversion frequency of 75% in 0.5 mgL-1 BAP and 0.2 mgL-1 NAA added medium. Rooting of regenerated plants was done on 0.5 mgL-1 IBA fortified half strength MS medium. So, this efficient protocol for callus induction, proliferation, somatic embryogenesis can be used for rapid propagation of Gladiolus communis.

Arbuscular Mycorrhizal and Endophytic (DSE) association in the dominant grasses of Melghat Forest (Phase -II), India
By: P.W. Deotare , S.P. Khodke , R.C. Maggirwar , S.K. Kharwade
Page No : 211-224
Abstract :
Soil fungi play a crucial role in producing fundamental ecosystem services such as soil fertility, nutrient cycling and establishment of plant community dynamics in the forest. Arbuscular mycorrhizal fungi (AMF) are one of the most important members of this soil microbial community in the ecosystem. They are beneficial soil symbionts fulfilling a key function in the complex networks of belowground biotic interactions. As Melghat Tiger Reserve of Satpura terrain India was not surveyed earlier by anybody to explore AMF diversity associated with grasses, we have carried out the survey in two phases. In the phase II of study, different grass species belonging to 35 species of 27 genera from core region were screened for association of AMF and dark septate endophyte (DSE). All these grasses were randomly collected from 9 different sites. Sporobolus indicus var. fertilis was found to be the most dominant grass species. The composite soil sample was prepared for each site and used for physico-chemical analysis by standard methods and their correlation study was carried out.
The rhizosphere soil samples were used to extract AMF spores and out of 1214 viable spores from 9 different sites in all 25 different AMF species representing 4 genera were identified. The mean % AMF was found to range between 5.83 to 47.31,% DSE from 0.22 to 29.43 and spore count from 0.66 to 65.33. Acaulosporas crobiculata Trappe was the most dominant AMF species. The roots showed hyphal penetration and appressorium, vesicles, H-connections and Y-junctions of hyphae, hyphal coils, intraradical spores, extraradical hyphae and spores which confirmed the AMF association. Various types of arbuscules have been reported such as in 17 grasses Arum type, in 28 grasses Paris type and in 2 grasses intermediate type. Intra radicle spores were found in 7 grasses.
The grass family is one of the largest and important families of the plant kingdom. It has great adaptability and is essential component of all type of ecosystems. In present investigation the consistent colonization of AMF along with DSE association with grasses suggests that these fungi have a significant ecological function. Such studies could provide very useful information for the maintenance of special habitats like Melghat Tiger Reserve forest. We need to design further studies to understand the significance of the coexistence of these fungi at the ecosystem level by using some molecular tools

Variable antioxidative responses to salt (NaCl) stress among seven different sesame (Sesamum indicum L.) varieties
By: R. Desingh , G. Kanagaraj
Page No : 237-244
Abstract :
Antioxidant characteristics were determined in seven sesame (Sesamum indicum L.) varieties (PAIYUR-1, SVPR-1, TMV-3, TMV-4, TMV-5, VIR-1 and VIR-2) subjected to salt stress of different concentrations (0, 40, 80 and 120mM) as a basal dose and sampling was done in leaves on 30th Days After Treatment (DAT). Leaf extracts of TMV-3 showed higher antioxidant enzyme activities (SOD, CAT, GR, APX and POD), while the lowest activities were recorded with PAIYUR-1. Lower rates of membrane lipid peroxidation and electrolytic leakage were noticed in the leaves of TMV-4 under salt stress. The leaves of TMV-3 and TMV-4 accumulated more proline, glycine betaine and abscisic acid under salt stress while lower content in PAIYUR-1 and VIR-1. Our data revealed that among seven sesame varieties TMV-3 and TMV-4 have efficient antioxidative characteristics which could provide better protection against oxidative stress in leaves under salt stressed conditions.

Pollen Viability Study of Solanum erianthum D. Don
By: Soumi Ghosh , Tustu Mondal , Anjalika Roy
Page No : 261-265
Abstract :
Pollen viability tested in Solanum erianthum D. Don by stain tests and in vitro pollen germination to ascertain the effects of essential compounds on pollen germination for designing efficient seed setting. Three stain tests (TTC, acetocarmine and safranin) and different growth media test e.g. sucrose, boric acid and gibberellic acid (alone and in combination) were done for pollen viability. The flowers generally open at 04:30 to 07:00 AM, after which anther dehiscence takes place. TTC test was more reliable. Percentage of germination was low in sucrose or boric acid medium. Maximum germination and pollen tube development was in 25% sucrose solution with 100 ppm boric acid. The gibberellic acid added to the basal medium reduced the germination rate. Accurate nutrient medium is required for proper growth and development of pollen tube.

Effect of Salinity Stress on Growth Performance, Cellular Responses and Antioxidant Production Capacity of Medicinal Plants
By: Malini Bhattacharyya , Puneet S. Singh , Babita Patni
Page No : 281-287
Abstract:
Soil salinity is a condition of the presence of a high amount of salt ions in the soil. Salt ions are toxic for plants. It is also harmful for medicinal plants. High salt concentration in the soil causes necrosis, rupture in the cell membrane and tissue degradation. But in plants, salinity stress acts as an elicitor of secondary metabolites. The saline condition helps in the up-regulation of defense mechanisms. For that reason, the accumulation of a large number of secondary metabolites happens. These could be beneficial for industries as well as transgenic research. In this review, we discussed the significance of salinity stress on medicinal plants growth pattern, cellular signalsand secondary metabolites up-regulation.

By: Nandini Girish , Vikas Vaidya , Seema Sapale
Page No : 295-302
Abstract:
Wagatea spicata (Dalzell) Wight (Moullava spicata (Dalzell) Nicolson) is a plant of the western ghats of India. The plant has been popularly used in tribal medicine as a cure for respiratory and skin disorders in the form of its roots and stem bark respectively. [8,16] However, the folklore does not give much account of the benefits of the leaves of the plant. Three phytoconstituents have been isolated and characterized using advanced techniques like the Infra-Red (IR) spectroscopy, Gas Chromatography-Mass Spectrometry (GC-MS) and Nuclear Magnetic Resonance (NMR) spectroscopy from the said plant. [12,13]
In order to establish the additional quality parameters, the prime objective of the present work was to assess the phytochemical profile of the plant. Effort was made to quantify 13 docosenamide, ntetracosanol-1 and squalene from the leaf extracts of Wagatea spicata using GC-MS. A simple, precise and accurate GC-MS method has been established for simultaneous quantitation of three components (13 docosenamide, squalene and n-tetracosanol-1) from Wagatea spicata.

Elucidating the Significance of Nitrogen requirements in Rice Cultivation: Review
By: Babita Patni
Page No : 313-321
Abstract:
High N loss and low N use efficiency (NUE), caused by high N fertilizer inputs and inappropriate fertilization patterns, have become debating issues in the rice (Oryza sativa L.) Nitrogen (N) is the most important nutrient in irrigated rice production. The high yields of irrigated rice also gets associated with large applications of fertilizer N (Cassman et al., 1998). Although N supply drives productivity, low fertilizer N use efficiency is a major characteristic of irrigated rice systems (Cassman et al., 1998). The low fertilizer N use efficiency has to be increased in the next decades to increase rice production to meet the food demands of a rapidly growing population (Jing et. al. 2007). Rice is one of the most important food crops in China, accounting for about 28% of the total grain-sown area, 43% of total grain production, and 40% of total calorific intake in the country (Huang et al., 2001). Approximately, 30% of the nitrogen used as fertilizer in the world is consumed in China of which rice crop consumes about 37% (Peng et al., 2002). The average rate of N application for rice production in China is high and N use efficiency is low when compared with other major rice growing countries (Peng et al., 2002). Reduction of N loss enhances both N in the soil and N use efficiency, alongwith reduced environmental costs associated with denitrification and leaching of NO3 (George et al., 1993). Nitrogen fertilizer use efficiency in irrigated cultivation is lower than that of dryland rice with or without covering the soil by plastic film (Ai et al., 2003). Hence, it is important to improve N use efficiency in the rice crop in the world (Lin et. al., 2006).We must understand role of nitrogen in rice production because nitrogen is an essential plant nutrient being a important component of amino acids, nucleic acids, nucleotides, chlorophyll, enzymes, and hormones required for rapid plant growth and improves grain yield and grain quality through higher tillering, leaf area development, grain formation, grain filling, and protein synthesis. In this regard the article has focused on how the nitrogen fertilizer is applied, what is the impact of fertilizer nitrogen dose on morphophysiological, biochemical and yield attributes of rice. However, future research is required to investigate the most appropriate urea application sites and fertilization nitrogen levels for different soil types. Therefore, we could assume that adoption

Evaluation of Drought Stress Management using ACC Deaminase Producing Plant Growth Promoting Rhizobacteria
By: Raja A , Prabakaran P , Ezhilarasu A , Ammu D
Page No : 335-341
Abstract :
The application of plant growth promoting rhizobacteria (PGPR) in agro-ecosystems is considered to have the potential for improving plant growth under drought tolerance. In the present study four different bacteria were isolated from paddy field. The isolates were identified as Pseudomonas fluorescens, Enterobacter sp, Bacillus subtilis and Rhizobium sp. All the four isolates were initially selected for their ability to produce IAA, phosphate solublization, siderophore production and ACC deaminase. Among them, Rhizobium sp and Pseudomonas sp were found to be potent isolates capable to produce siderophore, Acc deaminase and tolerate drought induced by PEG. Rhizobium sp showed the highest level of ACC deaminase and could efficiently enhance the root and shoot growth ratio followed by Pseudomonas fluorescens. The results of bacterial treatment were significant at p < .05 and not significant in control. These results suggest drought tolerant Pseudomonas sp and Rhizobium sp from V. radiatae could enhance plant growth under drought stress conditions and serve as effective bioinoculants to sustain agricultural production in arid regions.

Effect of Biochar on Soybean yield and Soil Properties in Semi-arid Vertisol
By: R.S. Oak , D.D. Sarode , J.B. Joshi , S.A. Chavan
Page No : 367-375
Abstract :
Biochar is a novel soil conditioner with a potential for long term improvement in soil fertility and sustainability of agriculture. However, its effects are dependent on production conditions, feedstock, soil, agro-climate, crop type and application rate. Agronomic potential of biochar is less known in vertisols of hot semi-arid tropics for important oilseed crops like Soybean, especially at practically feasible application rates. Field experiment was performed in a completely randomized block design on a typical vertisol of Satara district, Maharashtra. Effect of biochar produced from mixture of crop residue and wood waste was studied on soybean crop and soil properties. The study involved total eight treatments including control, three application rates of biochar(2, 3.5 and 5 t ha-1) alone, recommended dose of chemical fertilizers (25kg N ha-1and 50 kg P ha-1) (RDF) and combined application of biochar treatments in combination with RDF. Significant adverse effect of biochar was observed on grain yield and soil properties. Highest grain yield was observed with RDF treatment (1.98 t ha-1), which was 40% higher than control. Compared to the RDF, grain yield of sole biochar 2 (1.07 t ha-1), 3.5 (1.3 t ha-1) and 5 t ha-1 (1 t ha-1) recorded a decline of 45.8, 34.5 and 49.7 % respectively. Compared to RDF, RDF plus biochar at 2 (1.6 t ha-1), 3.5 (1.65 t ha-1) and 5 t ha-1 (1.69 t ha-1) recorded a grain yield decline of 19, 16 and 14.3 % respectively. Thus, biochar application upto5 t ha-1 produced negative effect on soybean yield. Soil electrical conductivity and plant tissue phosphorus and magnesium concentration followed the pattern of grain yield. Thus the effect of biochar was mediated by the interaction of biochar with soil nutrients. Further investigation on biochar-nutrient interactions in soil, effect of nutrient rich biochar and of biochars with higher labile carbon are important in context of Indian vertisols.

Brassinosteroids: Relevance in Biological Activities of Plants and Agriculture
By: A. Nishant Bhanu
Page No : 1-15
Abstract
Crop production is challenged by increasing food demands of a burgeoning population, fatigued natural resource base and uncertainty of climate optima. It is indispensible to alleviate the Crop production by using plant breeding or by applying economic levels of certain compatible growth regulators. In the category of phytohormones, brassinosteroids (BRs) has emerged as a new paradigm that elicits diverse physiological response in amelioration under different biotic and abiotic stresses. Intensive study has been carried out in the last few years to understand the role of brassinosteroids in plant function. They participate in regulation of diverse vital physiological processes in plants, such as elongation, germination, photomorphogenesis, reproductive organ development and ameliorate various biotic and abiotic stresses. The objective of this article is to unveil the importance of brassinosteroids in the plant physiological activity and potential agricultural uses.

Abstract
Potato is vegetatively propagating crop and sprouted tubers or pieces of them can be used as the initial propagating material. There is intrinsic demand for the quality seed tubers and many methods evolved for the production of the seed tubers with their own pro and cons. Aeroponics is recently developed and widely accepted method for the production of the mini-tubers and has the potential to produce clean potato seeds. In order to understand the genotypic differences, we have analysed the performance of the four Indian potato varieties namely, Kufri Megha, Kufri Himalini, Kufri Girdhari and Kufri Kanchan under aeroponics system with the uniform growth and nutrient conditions. Data were collected on major aspects like growth parameters and yield. By considering the overall yield parameters, Kufri Kanchan is performing best followed by Kufri Himalini in aeroponics based mini[1]tuber production system.

Impact of Salinity on Growth and N2 -Fixation in Melilotus indicus
By: M Muruganandam , Parveen Abbasi , Kumari Sunita , Malvika Srivastava
Page No : 109-119
Abstract
The yellow sweet clover, Melilotus indicus, has immense potential for reclamation of degraded lands, particularly salt-affected soils, and use as fodder, green manure, medicinal herb and such other socio[1]economic and environmental benefits like nitrogen fixation owing to its higher nodulation capacity, nitrogenous activities and nitrogen fixation rates as compared to other legumes. Also, it is diversely used as anthelmintic, antipyretic, antispasmodic, emollient, analgesic, insect repellent, health tonic and as astringent. In the present study, young sweet clover plants were treated with four different NaCl concentrations (50, 100, 200 and 300 mM, milli Moles) to study the impacts of salt content, especially on growth (biomass and leaf area), nodular status (number, shape, colour), nitrogenase activity, nitrogen and protein contents and N2 -fixation abilities against the untreated control plants from day 25 to 65 at every 10 days interval. While all the study parameters decreased at 200 and 300 mM NaCl salt concentration, the mild concentration (100 mM NaCl) registered a relative increase in all parameters and gave better response, as compared to control all through the study period except for the number of nodules, which declined after 45 day growth in all the treatments including control. The results indicate that M. indicus could be cultivated on moderately saline habitats, which would help utilization or reclamation of unproductive saline lands towards production of the important herb.

Role of Nitrogen and Sulfur in Mitigating Cadmium induced Metabolism Alterations in Plants
By: Shabir H. Wani , Abbu Zaid , Javaid A. Bhat , Khalid Z. Masoodi
Page No : 121-141
Abstract
Cadmium (Cd) is among one of the highly toxic heavy metals, which has deleterious impacts on agricultural productivity. Currently, several sustainable strategies are being used to attenuate Cd[1]stress tolerance at cellular, molecular as well as whole plant levels. Nitrogen (N) and sulphur (S) assimilation pathways have been shown to play important roles in Cd detoxification by improving the physiology of plants. The N and S assimilation is required in various biosynthetic pathways involved in stress tolerance and mobilization of adaptive mechanisms of plants, and both N and S act to maintain an elevated pool of plant metabolites. In this review, we discuss the impact of Cd stress and its mitigation by deciphering the close coordination of N and S in efficiently alleviating Cd induced altered metabolism of plants, which is critical for the development of plant-based strategies for the remediation of Cd contaminated agricultural soils and increasing crop productivity and safety. Our review also focuses on the interactive roles of N, S and principal metabolites in enhancing Cd stress tolerance of plants. Mobilization of plant

By: Vineet Soni , Sunita Parihar , Manisha Rathore
Page No : 159-164
Abstract
Organic agriculture is a production system that integrates various farming methods and natural ecological processes to improve crop productivity. In present study, through the analysis of polyphasic chlorophyll fluorescence OJIP kinetics, we investigated the effects of panchagavya, vermicompost (VC), and farmyard manure (FYM) on photosynthetic performance of Triticum aestivum L.var. GW366. Higher values of phenomenological energy fluxes (absorbance per cross section-ABS/CS, trapped energy per cross section-TR/CS and electron transfer per cross section- ET/CS), density of active PS-II reaction centers (RC/CS) and chlorophyll contents were recorded in plants germinated on 3% panchagavya. Similarly, higher performance index on cross section basis (PIcs) was found in plants growing on panchagavya, as compared to plants developed on VC and FYM. Similarly, application of panchagavya also enhanced shoot biomass and root length in T. aestivum. These results clearly reveal that panchagavya can be used as a low-cost preparation to enhance photosynthetic potential in crop plants.

Individual and Combined Effect of Drought and Salinity on Electrolyte Leakage, Relative Leaf water content and Lipid peroxidation in Brassica juncea sp. supplemented with Salicylic acid
By: Dheera Sanadhya , Rajani Chauhan
Page No : 171-182
Abstract
Salinity and Drought are the major abiotic factors that affect the membrane integrity. The main check points to evaluate the damage on cell membrane are electrolyte leakage (EL) and Relative Leaf Water Content (RLWC). The level of lipid peroxidation indicates the severity of damage. Our study was aimed at evaluating the effect drought, salinity and their combined stress on membrane integrity and response of salicylic acid in mitigating the stress. The experiment was carried out under in-vitro conditions where two sets of 7-d-old plants were exposed to three levels of water stress (5 , 10 and 15 % PEG), salt stress (50, 100 and 150 mM NaCl) and combinations (Combination (1) 2.5 % PEG + 25 mM NaCl; Combination (2) 5 % PEG + 50 mM NaCl; Combination (3) 7.5 % PEG + 75 mM NaCl), another set of seedlings were also supplemented with same stress conditions along with the application of SA (8 ?m). These stresses significantly reduced the RLWC and increased EL content. The molecules of lipid peroxidation MDA and H2 O2 content also showed the increased value in the mustard leaves. Toxic effects induced by these osmotic stresses were completely overcome by the exogenous application of SA

Abstract
Many moss species have ability to survive desiccation-a more severe state of dehydration than drought. At this stage no liquid phase remains in the cellular system, but the plants subsequently recover normal metabolism within minutes or hours upon rehydration. In order to understand the mechanisms of rapid photosynthetic recovery in mosses upon rehydration, we investigated the kinetics of the photosynthetic recovery process in desiccation tolerant moss Semibarbula orientalis through polyphasic chlorophyll a fluorescence OJIP measurements. The maximal quantum efficiency of PSII (Fv/Fm) was increased from 0.09 to 0.5 within 6 min of rehydration. Results clearly reveal that the moss

Abstract
Present work was carried out to check the feasibility of TS by the application in GS with the objective to examine the influence of amendment on the soil as well as on plant (C. procera and L. camara) grown in amended soil. For this purpose 0%, 5%, 10%, 20%, 30%, 50%, 75% and 100% of GS amended with TS and samples were investigated for physicochemical and heavy metal status of soil. The effect of amendments on seed germination, shoot, root and total biomass along with heavy metal accumulation by plants and their caliber to use in phytotechnique were also sought. pH, EC, OC%, available N, P, K, exchangeable Ca and Mg and heavy metal content in amendments increased in accordance with TS. All selected parameters measured for plant growth and development increased significantly till 20% amendment after that there was retardation in data except total heavy metal accumulation by plants. BCF >1 was calculated for C. procera with TF<1 whereas both were <1 for L.camara, which indicate its potential for retention of Cr and advocate that C. procera is a better candidate to consider as phytostabilizer of Cr from TS.

Optimization of Growth Medium and Salt Concentration for the Growth of Dunaliella parva isolated from Sambhar Lake (Rajasthan, India)
By: Anmol Bhargava , Arvind Pareek
Page No : 229-232
Abstract
Microalga Dunaliella is a green, halotolerant genera mostly occur in hypersaline environment. This alga is the richest source of glycerol and ?-carotene, used as a food source in aquaculture. Dunaliella also accumulate others nutrients like lipids, vitamins and proteins. Modified Johnsons medium is widely used for culturing species of Dunaliella however, without adding micronutrients the growth of algae was slow. Another medium which is suggested by Ramaraj is also suitable for culturing Dunaliella species. A study was conducted to investigate the effect of these two medium on green alga Dunaliella isolates from Sambhar salt lake. The results of this experiment showed that Dunaliella species grew faster in Ramaraj medium as compared to Johnson modified medium. In another experimental setup, Dunaliella isolate from Sambhar Lake, was cultured in Ramaraj medium and were studied for its growth rate at different salinities (0.5M to 5.5M NaCl). The effect of salinity stress on their growth was investigated. Dunaliella strains were shown to withstand large variations of salinity of the growth medium, 0.5 -5.5 M NaCl. Growth of Dunaliella showed declined if NaCl concentration was above 5M in medium. This study showed optimum growth medium for Dunaliella sp. isolated from Sambhar Lake is Ramaraj medium (pH7.5) and optimum salt concentration for growth is 1.5M -2M NaCl.

How to survive in a salty desert: An adventure study with Suaeda fruticosa
By: Silas Wungrampha , Rohit Joshi , Sneh L Singla-Pareek , Ashwani Pareek
Page No : 257-261
Abstract
Salinity stress is one of the major abiotic stresses limiting crop productivity in arid and semi-arid regions. Halophytes play increasingly important roles as models for understanding the salt tolerance in plants and as genetic resources contributing towards the improvement of salt tolerance in crops. Suaeda fruticosa L. (Amaranthaceae) grows under extremely saline conditions and under osmotic stress near Sambhar Lake, which is the largest inland playa within the Thar desert of Western India. The ability to regulate photosynthetic machinery may help S. fruticosa to ensure population succession under extreme environmental conditions. Our expedition to Sambhar Lake allowed us to conclude that higher stability of Photosystem II (PSII), along with the enhanced resistance to the O2 evolving complex and the reaction centers of PSII, is responsible for the tolerance of S. fruticosa to salinity stress. Understanding the molecular mechanism and stress signaling in Suaeda sp. for stabilization of its photosynthetic machinery and maintenance of carbon balance under osmotic stress are expected to be extremely useful in designing crops for saline environments. We also describe here the ambiance of our bus trip from New Delhi to Sambhar Lake that led to the unique way of doing collaborative research with Govindjee, a leading authority on the use of chlorophyll a fluorescence in photosynthesis.

Page No : 263-265
Abstract
The present study was conducted to investigate the biochemical changes during in vitro rhizogenesis from nodal explants of Asparagus racemosus Willd. Induction in activity of acid invertase and ?-amylase was observed prior to root induction. Similarly, increased acid phosphomonoesterase activity was noticed during the emergence of root primodia. Starch content was initially decreased and then increased in nodal explants of A. racemosus cultured on rooting medium. A decrease in starch content reflects high energy demands during initial phase of rhizogenesis in A. racemosus. This study indicates that induction phase of root formation is governed by various biochemical changes in A. racemosus.

Edible Coating Delay Ripening and Influence the Quality and Shelf life of Fruits and Vegetable
By: A. V. Joshi , T.V.R. Rao
Page No : 1-7
Abstract
Fruits and vegetables are highly demanded in the market because of its nutritional content like antioxidants, vitamins, minerals, flavonoids and phyto-chemicals. Short shelf life is a major problem of fresh produces like fruits and vegetables, and it is only because of its perishable nature. Fruits and vegetables are spoilt by insects, microorganisms, pre and post harvesting conditions during transport and storage. Post harvest loss mainly due to microbes, insects, respiration and transpiration. Nowadays, Preservation of fruits and vegetables is a big challenge for world. Edible coating is an effective method which provides protective edible covering to fruits and vegetables and extends the shelf life by control moisture transfer, gas exchange or oxidation processes. The major quality parameters of fresh fruits and vegetables contributing to the marketability are appearance, texture, colour, flavour, nutritional value and microbial safety. Edible coating can influence the ripening process by delayed the changes in weight loss, pH, total soluble solids, decay occurrence, total sugars, total phenols and ascorbic acid content, and also affect the cell wall modifying enzymes (polygalacturonase (PG), pectinase and cellulase) and browning related enzyme (Polyphenol oxidase (PPO)).

Abstract
Anthocyanins are an important group of plant flavonoids which are responsible for imparting pink, red and blue coloration in a large number fruits, flowers and other plant parts providing an attractive option for colouring the processed food since long. The present study describes production of callus cultures from young inflorescence explants of Salix tetrasperma Roxb. It is a plant of medicinal importance and also a preferred tree species for biofuel plantations. 1.0 ?M 2,4-D found to be best for callus development and proliferation with 100% response after 4 weeks. Of the several concentrations of different external stimuli tested, 6-benzyladenine (4 ?M) produced the best results with 2 fold increase in anthocyanin accumulation in comparison to control. Cadmium Chloride (CdCl2 ) treatment was found to exert a negative effect on biomass production with a nonsignificant increase in pigment production. The harvesting time of 4 weeks was found to be the optimum for highest pigment recovery beyond which the cells of callus mass start dying due to the browning effect of oxidized phenols.

Recent Perspectives towards Enhancing Drought Tolerance in Sugarcane
By: Arvind Kumar , Gulzar S Sanghera
Page No : 23-35
Abstract
Sugarcane being a C4 crop produces a large amount of biomass is a water-loving crop, its requirements for water and fertilizers are equally very high. Water is already a scarce commodity in many parts of the world and predicted climate changes will aggravate the situation in future. Due to glycophytic nature of this crop, drought conditions interfere with sugar production by affecting growth rate, yield of the cane, juices of lower sucrose contents and the sucrose content of the stalk. Thus, drought may reduce sugarcane yield up to 50% or even more being a multi-dimensional stress, it causes various physiological and biochemical effects on plants. Enhancing the tolerance of this crop to abiotic stresses such as drought has therefore proved to be somewhat elusive in terms of plant breeding. Researchers are looking for different agronomic and physiological traits, which could lead to adaptation to these conditions or be correlated to drought tolerance. This article is an attempt to put emphasis on some potential strategies like physiological, biochemical and biotechnological that could be used in breeding for development of superior sugarcane varieties that improve crop productivity in water stress environments.

Abstract
Pot experiments were carried out to assess the extent of cadmium stress-induced biochemical changes in mungbean (Vigna radiata L.) genotype HUM-1 and its alleviating effect in the presence of plant growth regulators salicylic acid (SA) and paclobutrazol (PBZ), at different growth stages. All the treatments showed in improvement of biochemical parameters viz. chlorophyll a, b, carotenoid content, total soluble sugar and enzyme activity NR, SOD, APX etc. Chlorophyll content was found to be drastically reduced under plants exposed to both the levels of Cd stress and devoid of treatment with either of plant growth regulators. Paclobutrazol @ 100 ?M has been found to be more significant in mitigating, Cd stress, as compared to salicylic acid at early as well as late growth stages. The total soluble sugar content increased in plants treated with paclobutrazol @ 50 ?M. In all the other treatments sugar content was found to be lower than control plants, devoid of both Cd stress as well as plant growth regulator application. Paclobutrazol @ 100 ?M has been found to be more significant in mitigating Cd stress, as compared to salicylic acid at early as well as late growth stages. Chlorophyll content was found to be drastically reduced under plants exposed to both the levels of Cd stress and devoid of treatment with either of plant growth regulators.

Abstract
Rising demand of herbal medicine and environmental degradation necessitates the development of more productive management practices for many valuable orchid species. The Nitrogen Phosphorous and Potassium fertilization and 6-Benzylaminopurine application has been advised as a practice to address these trends. However, it is not known at what rate the plant would efficiently endorse the growth. Performance of three NPK ratios viz; (10:10:10), (20:10:15) and (30:10:15) with three dosages i.e. 1, 2 and 3 g L-1 for each ratio and nine concentrations i.e. 15, 25, 50, 75, 100, 125, 150, 175 and 200 mg L-1 of BAP supplement on two rare orchids Dendrobium densiflorum and Phaius tankervilleae was evaluated in green house condition. At 1 g L-1 of (30:10:15) ratio NPK application, both the species showed significantly highest plant height, leaf length, leaf width and number of leaves. Shortest time interval from inflorescence emergence to first flower opening was observed at 200 mg L-1. The results indicate that NPK with high N and K promote vegetative growth and the cytokinin (BAP) 200 mg L-1 has great potential for speeding up flowering process in both the genera.

Plant Growth Promoting Rhizobacteria and their Roles as Fungal Biocontrol Agents: An Overview
By: A. Hemantaranjan , Deepmala Katiyar , P. Dwivedi
Page No : 127-136
Abstract
In the last couple of decades, plant growth promoting rhizobacteria (PGPR) have been increased with impressive enthusiasm to examine growth, development and yield potentiality of crop plants being less destructive to nature and cutting short the cost of certain composts. Pathogenic fungus affecting plant health is a major and incessant threat to crop production and ecosystem unwavering worldwide. Agricultural production has been strengthened over the past few years, even though producers became more and more dependent on fungicides supportive of crop protection for the obvious reason of monetary stability and livelihood. Besides this, fungicides cause harmful effects on environment ultimately damaging plant health; its use needs to be reduced. Different groups of microorganism in soil have been identified compatible to improve physiological processes at different phenological stages and ultimately benefiting crops for optimizing their potential in several ways. These microorganisms are colonized in roots or rhizospheric soil and are alluded as plant growth promoting rhizobacteria due to its involvement in a variety of plant growth promoting mechanisms consisting of the mobilization of soil compounds (phosphorous and metals), the protection of plants under stressful conditions for counteracting the negative impacts of stress, making them available for the plant to be used as nutrients (nitrogen fixation; phosphate solubilization), siderophore production, defense against phytopathogens, reducing plant diseases by producing antibiotics and HCN, phytohormones (indole 3-acetic acid, cytokinin and gibberellin) production and so on. Utilization of plant rhizobacteria for agricultural advantages has increased its overall significance. The insights developed are crucial for extending relevant researches extensively in the requisite section of biocontrol for enhanced crop production. Therefore, based on recognized roles of PGPR, this has been thoughtfully considered as one of the vital areas of crop improvement programme under normal or stressful condition.

Abstract
Sugarcane (Saccharum spp. complex) is an important sugar crop of subtropical region (NWZ zone) comprising states of Punjab, Haryana, Uttrakhand, Uttar Pradesh and Rajasthan of the country. In Punjab, it is the second most important industrial crop after Cotton, being cultivated on an area of 95 thousand hectares that caters the need of 16 (9 cooperative and 7 private) sugar mills running in the state. Sugarcane scientists and technocrats of the state associated in the improvement of sugarcane crop through various conventional and non-conventional approaches encounter problems of narrow genetic base of crop, complex genome, poor fertility, genetic recombination as well as long breeding selection cycle. During 2015-16 crop season, the concerted efforts of sugarcane scientists, sugar mills and farmers on various researchable aspects has led to harvest cane productivity of 750 quintals per hectare and recorded sugar recovery of 10.07 percent in the state. To sustain the sugar industry of Punjab, it is very important to advise sugarcane grower for the choice of the varieties and their planning based on different maturity groups, planting season and type of crop (plant/ratoon). At present, nine high yielding, good quality and red rot tolerant sugarcane varieties; 4 in early maturity group (CoPb 92, Co 118, CoJ 85 and CoJ 64) and 5 in mid-late group (CoPb 93, CoPb 94, Co 238, CoPb 91 and CoJ 88) have been recommended for commercial cultivation, of these three new varieties viz,, CoPb 92 (early) and CoPb 93 & CoPb 94 (mid-late) are found promising for cane yield, commercial cane sugar (CCS) and showing encouraging results among farmers and sugar mills. Since, sugarcane is the raw material for the sugar industry, its juice is used for the manufacturing of gur, shaker, sugar and cane tops are used as fodder while the byproducts of the sugar industry include bagasse, molasses, filter-cake, wax etc. The percentage of sucrose varies from 12-18% depending of the variety of cane, its maturity, condition of soil, climate and agricultural practices followed by the growers. In order to sustain cane crushing in mills, planting of varieties in early: mid-late (3:2), early (Autumn: Spring: Ratoon :: 1:1:1) and mid-late (Plant: Ratoon :: 1:1) ratios have been advocated. Besides, recent technological interventions like FIRB (furrow irrigated raised bed), sub-soiling (1mx1m), crop geometry (120mx30m paired row trench planting), single bud chip nursery raising and intercrops (wheat, cabbage, garlic, sarson, onion etc.) have resulted in enhancement of per unit area productivity of sugarcane. In addition, recommendation for management of borer complex (especially early shoot and top borer) with Coragen and Ferterra agro-chemicals have paid dividends to growers and industry in terms of cane production and sugar recovery. Therefore, execution of aforesaid planning and interventions through extension activities in mill command areas are advocated to sustain sugarcane agriculture for the benefits of growers and industry in the state.

Phytochemical screening of Celastrus peniculatus and Bacopa monnieri for neuroprotective capacity
By: Pallav Kaushik Deshpande , Ragini Gothalwal
Page No : 153-158
Abstract
Medicinal properties of plants are dependent on the presence of certain phytoconstituent. Various plants exhibits neuroprotective and cognitive enhancing effects. Phytoconstituents shows capacity to modulate the cholinergic system and to contrast oxidative stress. Individual alkaloids act as agonists and antagonists to a variety of neurotransmitter systems, for instance, direct binding to neuroreceptors and interference with neurotransmitter metabolism (e.g. cholinesterase inhibition), signal transduction, and ion channel function or by mimicking the structure of endogenous neurochemicals. In this study we had investigated the fundamental scientific bases for the use of medicinal plant by defining qualitative evaluation of crude phytochemical constituents present in Celastrus peniculatus and Bacopa monnieri both the plants are known to local folks and widely used to stimulate the nervous system but, Scientific validation is lacking. Successive extraction method was adopted by using various solvents according to polarity, from lowest to high (hexane, pet ether, ethly ether, acetone, methanol, ethanol, water). Extractive value in % for seeds of Celastrus paniculatus with various extract was 45.59

Triplex Forming Oligonucleotides: Sequence-specific Tools for Gene Targeting
By: Ritesh Kaur
Page No : 159-167
Abstract
Sequence-specificity is the key to effective genetic targeting. With specificity, targeted genes can be manipulated in multiple ways; without it, gene therapy agents become loose canons within cells. Triplex forming oligonucleotides (TFOs) bind in the major groove of duplex DNA with high specificity and affinity. Because of these characteristics, TFOs have been proposed as homing devices for genetic manipulation in vivo. Here we review work demonstrating the ability of TFOs and related molecules to alter gene expression and mediate genome modification in mammalian cells. Recent studies have established that TFOs can mediate targeted gene knock out in mice, laying the foundation for the potential application of these molecules in human gene therapy.

Abstract
Chickpea (Cicer arietinum L.) is one of the most important pulse crops of India and an important source of protein growing in semi-arid region. It has an extant to adapt to various stresses but it is yet susceptible to salinity stress. Salinity is one of the major abiotic stresses affecting crop production worldwide. It alters various physiological and biochemical attributes of crop plants. Phytohormones play an important role in combating stress. Methyl jasmonate (MeJA) and jasmonic acid (JA) are collectively referred to as jasmonates. This regulator has been evidently found to have alleviating effect on remarkable physiological traits in a number of crops under various abiotic stresses. Consequently, it was thought worthwhile to study the effect of methyl jasmonate on chickpea under salinity stress. This investigation was conducted using Avrodhi cultivar of chickpea in a pot culture experiment. Seeds were pre-soaked in MeJA @5.0?M and 10.0?M prior to sowing. Later, salinity was induced at preferred concentration of 100mM NaCl in the growing medium. Observations on different parameters were recorded at two intervals of 14 and 28 days after salt exposure. Morphophysiological traits studied include root length, fresh and dry weights of the plants root; biochemical parameters, viz., total soluble sugar, nitrate reductase activity and hydrogen peroxide. Data revealed negative influence of salinity on overall parameters studied. However, methyl jasmonate at the threshold level of 10?M MeJA was found to have alleviating effect of salinity significantly over 5?M MeJA. The positive impacts of methyl jasmonate in this investigation were registered.

Toxicity of Seed extracts of Pea Cultivars in relation to Trypsin inhibitory activity
By: Akhilesh Thakur , Amarjit K. Nath
Page No : 243-250
Abstract
Purpose: Trypsin inhibitors in the seeds of legumes can act as a feeding deterrent for insects by disrupting midgut proteases. This paper investigates trypsin inhibitors in pea cultivars. Design/Methodology/Approach: The seeds of seven different pea cultivars and the cultures of root knot nematode Meloidogyne incognita were used for biological screening of trypsin inhibitory activity (TIA). This was followed by partial purification of trypsin inhibitor from the screened pea cultivar by ammonium sulphate precipitation, ion exchange chromatography on DEAE-Sephadex (A50) column and gel filtration through Sephadex G-200 column. Findings: Field pea with maximum TUI/g seed weight and percent mortality of Meloidogyne incognita was then partially purified. A linear correlation between time of incubation and TIA was found till 25 min of incubation, whereas, per cent inhibition was linearily correlated to the amount of inhibitor upto 68.1 per cent inhibition. The inhibitor showed maximum TIA at 37?C indicating thermolabile nature. It had two pH optima at pH 7.5 and 9.0. Km value was found to be 0.227 mM. Trypsin inhibition was of non-competitive type with inhibitor constant (Ki) value in the region of 0.25 ?M. Originality/Value: Invaluable information on trypsin inhibitors in case of native legumes of Himalayan origin has been found. Outcomes of this study can be of immense importance in the development of insect resistant transgenic plants.

Calcium-Dependent Protein Kinases (CDPK) in Abiotic Stress Tolerance
By: Nirmal Kant Sharma , Hemant B Kardile , Vikrant , Ankita Sharma , Babandeep Kaur , Sushil Sudhakar Changan , Vinay Bhardwaj , Brajesh Singh
Page No : 259-265
Abstract
Environmental perturbation and biotic factors hinder the normal growth and development of the plants. These stimuli trigger the transient increase in the cellular Ca2+ level which in turn leads to altered protein phosphorylation and gene expression patterns. This signal transduction is carried out by three major classes of Ca2+-binding proteins viz. Calcium-dependent protein kinases (CDPKs), calmodulins (CaMs) and CaM-like proteins, and calcineurin B-like proteins. Out of these three kinases, CDPKs has a greater role to play in the higher plant under different physiological conditions. Here we have reviewed the potential role of these CDPKs in the model plant for providing abiotic stress tolerance. Similarly, we have mined the orthologous of CDPKs from the higher plant species. Among these, we have narrowed down our focus on the potato for exploiting the CDPKs potential in providing stress tolerance.

Abstract
Eight sugarcane genotypes including 3 standards representing mid maturing group were evaluated at Punjab Agricultural University, Regional Research Station, Kapurthala, during 2013-14 and 2014- 2015 under plant and ratoon crop in randomized block design. The experiment plot size in both years was 36 m-2 in three replications with an inter-row spacing of 90 cm. The data were recorded on seventeen cane yield and quality traits. Analysis recorded that genotypes used in the testing differed significantly with respect to all characters studied. The high phenotypic and genotypic coefficient of variation were observed for single cane weight in plant crop and pooled analysis respectively, while, in ratoon crop for CCS t/ha. Cane yield was positively significantly correlated with CCS t/ha, stalk length, single cane weight and NMC at 12 months under both plant and ratoon crop while, with stalk diameter, purity at 10 months, no. of shoots at 240 days under ratoon crop. Path analysis revealed high effect of single cane weight, cane diameter, and NMC at harvest on cane yield in both plant and ratoon crops. This study revealed that characters with high heritability coupled with genetic advance and positive association with cane yield and heaving high direct and indirect effects are advocated as selection criteria while selection to be made for higher sugar and cane yield. High indirect effect of number of shoots at 240 days and NMC at harvest, cane length and diameter and single cane weight were recorded that may be used for indirect selection.

Effects of Heat Stress on the Photosynthetic Apparatus in Commiphora wightii (Arnott) Bhandari
By: Vineet Soni , P.L. Swarnkar
Page No : 139-145
Abstract
Heat stress, whether transitory or constant, causes physiological, biochemical and molecular changes that adversely affect plant growth and productivity by reducing photosynthesis. To elucidate the photosynthetic adaption response under heat stress, we measured various photosynthetic parameters in C. wightii plants through polyphasic chlorophyll fluorescence OJIP analysis. Chlorophyll a fluorescence analysis indicates that plants are quite resistant and well developed physiologically to survive in heat stress conditions by maintaining their photosynthetic performance through increasing their light trapping and electron transfer efficiency at reaction center level. The high activity of reaction centers, despite their low density in heat strssed plants, indicate that the reaction centers have enhanced their activity to cope up with their meagre number. The study describes the physiological basis of heat tolerance and will, therefore, be useful in transgenics for the development of high temperature tolerant plants.

Abstract
Nearly, 3.1 million school age children suffer eye damages due to Vit- A deficiency and another 227.5 million are sub-clinically affected as per WHO report. Over 3 billion people in the world suffer from iron deficiency. A significant portion of people in developing countries relies largely on one or more of the staple crops such as rice, maize, wheat, potato and cassava for their nutrition. These crops are the main subjects of biofortification projects. In staple grains such as rice, improvement of some complex traits such as vitamin A is not possible using conventional breeding strategies, as there are no natural rice varieties rich in this vitamin. In developing countries, where vitamin A deficiency prevails, grain from Golden Rice is expected to provide this important micronutrient sustainably through agriculture. Since its original production, the prototype Golden Rice has undergone intense research to increase the provitamin A content, to establish the scientific basis for its carotenoid complement, and to better comply with regulatory requirements.

Page No : 167-180
Abstract
The development of new high yielding varieties of crop plant made possible by accumulation of beneficial alleles from plant genetic resources existing worldwide but still a significant portion of these alleles were not used as these were left behind during evolution and domestication process in the form of wild relatives and land races. Hence, the vast germplasm need to be relooked for novel alleles to further enhance the genetic potential of crop varieties for various agronomic traits. Based on gene and genome sequences available in public database, PCR strategies are devised to identify and isolate novel and superior alleles of agronomically important genes from a wide range of crop species to suitably organize for the development of improved cultivars. Allele mining can be effectively used for discovery of superior alleles are through

Abstract
Fourteen accessions collected from different locations in Northern India. Seeds of defined varieties grown in Rajasthan were procured from the Department of Plant Breeding and Genetics, S.K.N College of Agriculture, Jobner, Jaipur (Rajasthan) India were studied using Start Codon Targeted (SCoT) markers. Total thirty-six SCoT primers were screened to study the diversity, out of which thirty five primers could amplify reproducible bands. A part of that SCoT 20 primer could not amplify reproducible bands. These primers were selected for molecular characterization of fourteen Foeniculum vulgare accessions, which produced a total of 256 bands (7.0 bands per primer), of which 240 were polymorphic. The analysis revealed 85.69% polymorphism for SCoT, respectively. Similarity coefficient was used to detect the phylogenetic relationship, subsequently dendogram was constructed for SCoT data. The UPGMA cluster analysis revealed two distinct sub-clusters in the dendogram. In cluster1 thirteen accessions were grouping together whereas variety 6 present in cluster 2. Accession number 6 was different to all thirteen. The genetic diversity explained by gene targeted markers shows that SCoT marker can be very effective for characterization of genetic diversity in medicinal plant like Foeniculum vulgare.

Abstract
The experiment was conducted at the cage house in the Department of Plant Physiology, S.K.N. College of Agriculture, Jobner (Jaipur) to study the effect of brassinolide on physiological aspects of fenugreek (Trigonella foenum-graecum Linn) under drought conditions. Four fenugreek cultivars namely RMt-1, RMt-361, RMt-305 and Hissar Sonali were grown in ceramic pots under normal conditions till vegetative stage and then plants were sprayed with brassinolide (0.0, 0.25, 0.50, 0.75 and 1.00 ppm concentration) followed by half the plant population subjected to water stress by withholding irrigation. The observations were recorded at 7-days after first (pre-flowering) spray and 17-days after first spray of brassinolides. It was observed that 1.0 ppm concentration of brassinolide was most effective under both non-stress and water stress condition. It may be concluded that RMt305 was drought tolerant, among cultivars studied and brassinolide showed positive response towards all the physiological parameters by reducing the adverse effect of drought stress.

Abstract
Three out of the eight Millennium Development Goals (MGDs); Eradication of poverty and hunger, reduction in child mortality and improving maternal health can be well addressed through food fortification initiatives. Half of the world population, particularly India relies on rice as the main food source being its main source of dietary energy. Since rice does not contain essentials vitamins like ?-carotene, therefore Indian population that is totally dependent on rice are at high risk of developing vitamin A deficiency. In India the burden of Vitamin A deficiency (VAD) amounts to an annual loss of 2.3 million disability-adjusted life years (DALYs). Jammu and Kashmir stands fifth after Mizoram, Goa, Assam, Manipur and West Bengal in having the highest VAD cases in the age group of 10-14 years. The prevalence of biochemical VAD among under-five years children in India is 62%, which is among the highest in the world and accounts for 330000 deaths in India alone (WHO, 2009). Combating VAD among an estimated 12 million preschool children, it is claimed that government programs to provide vitamin A supplements to the affected children are expensive and complicated. And it is asserted that conventional, non-GM methods of introducing or enhancing ?-carotene in other staple crops have been unsuccessful. Failure of Golden rice 1 and 2 in circumventing VAD is due to less amount of available pro-vitamin A. Assuming a ?-carotene to vitamin A conversion rate of 1:1, 200 grams of

Punica granatum, commonly known as pomegranate (Pg), is a member of the monogeneric family, lythraceae, and mainly found in Iran which is considered to be its primary centre of origin. Pg and its chemical components possess various toxicological and pharmacological properties including antioxidant, anti-inflammatory (by inhibiting pro-inflammatory cytokines), anti-cancer and anti[1]angiogenesis activities. They also show inhibitory effects on invasion/motility, cell cycle, apoptosis, and vital enzyms such as cyclooxygenase (COX), lipooxygenase (LOX), cytochrome P450 (CYP450), phospholipase A2 (PLA2), ornithine decarboxylase (ODC), carbonic anhydrase (CA), 17beta[1]hydroxysteroid dehydrogenase (17b-HSDs) and serine protease (SP). In addition, they can stimulate cell differentiation and possess anti-mutagenic effects. However, the exact mechanisms for its pharmacological and toxicological properties remain to be uncertain and need further evaluation. These properties strongly suggest a wide range use of Pg for clinical applications. This review will discuss the areas for which Pg has shown therapeutic properties in different mechanisms.

Heat Stress in Plants: Sensing and Defense Mechanisms
By: Akanksha Sehgal , Kumari Sita , Harsh Nayyar
Page No : 195-210
Abstract
High temperature has become a global concern because it severely limits plant growth, metabolism, and productivity worldwide. Plant growth and development involve numerous biochemical reactions that are sensitive to temperature. Plants possess a number of adaptive, avoidance, or acclimation mechanisms to cope with heat stress situations. In addition, major tolerance mechanisms that employ proteins, osmoprotectants, antioxidants, and other factors involved in signaling cascades and transcriptional control are activated to offset stress-induced biochemical and physiological alterations. Plant survival under elevated temperatures depends on the ability to perceive the heat stress stimulus, generate and transmit the signal, and initiate appropriate physiological and biochemical changes. High temperature-induced gene expression and metabolite synthesis also substantially improve tolerance. The physiological and biochemical responses to heat stress are active research areas, and the molecular approaches are being adopted for developing heat tolerance in plants. Recent developments in molecular genetics have contributed greatly to our understanding of the genetic basis of heat stress tolerance. This has led to the development of abiotic stress tolerant plants with yield advantage by modulation of the expression of genes that encode for enzymes involved in the biosynthesis of osmoprotectants (e.g. Proline, sugars, sugar alcohols, glycine betaine and polyamines), anti-oxidant enzymes, protective proteins (e.g. HSPs), transporters, regulatory proteins, kinases and transcription factors. The present article discusses the various defense mechanisms to counter heat stress responses encompassing different pathways that provide tolerance during high stress.

Microsatellites : A Review
By: C P Malik , Akhil K. Sankhla
Page No : 1-11
Abstract
Microsatellites have evolved as most adaptable and popular genetic marker in a multitude of plant systems. Due to their co-dominant, hyper-variable and multiallelic nature, they are the leading markers of choice for genetic finger printing, conservation biology, plant breeding and phylogenetic studies. SSR mutations or microsatellite instability (MSI) can result in either expansion or contraction of repeat units. The significance of microsatellite markers is because of their abundance in the genome, their single locus nature, ease of assay, mendelian inheritance and codominant nature. Despite the development of a new set of SSR markers for a species remained time consuming and expensive for many years. However, with the recent advancement in genomics, new strategies and protocols are now available for the generation of SSR markers. This chapter presents an overview on microsatellite markers, their applications and utility with an insight on the various strategies used for the development of microsatellite markers.

Abstract
A field experiment was conducted during kharif season 2013 to evaluate 72 genotypes of cowpea to estimate genetic variability, heritability and genetic advance of ten quantitative characters. Analysis of variance revealed highly significant difference among genotypes for all the characters indicated that considerable amount of genetic variability was present in the experimental material which can be exploited for improvement of seed yield in cowpea. Genotypic and phenotypic variance were recorded highest for plant height (358.69, 378.69) followed by pod wall proportion (38.30, 41.27) and lowest for primary branches per plant (0.30, 0.50). High GCV and PCV were recorded for plant height (38.65, 39.70) followed by 100-seed weight (25.68, 26.21) and pod wall proportion (20.49, 21.24). Whereas, moderate estimate of GCV and PCV were recorded for seed yield per plant (15.93, 18.76) followed by pods per plant (14.86, 19.69), pod length (14.93, 16.28), primary branches per plant (12.77, 16.77) and seeds per pod (12.98, 14.76). High estimates of heritability along with high genetic advance as per cent of mean was recorded for 100-seed weight (95.95, 51.81) and plant height (94.78, 77.52) which indicated major role of additive gene action in the expression of these characters while high heritability along with moderate genetic advance as per cent of mean was recorded for pod wall proportion, seed yield per plant and pod length which indicated these characters was mainly governed by non additive gene action.

By: Bhuri Singh , K.C. Sharma , E.V.D. Sastry
Page No : 29-32
Abstract
A field experiment was conducted during kharif season 2012 to evaluate 55 (10 parents and 45 hybrids) of pearl millet to estimate genetic variability, heritability and genetic advance of twelve quantitative characters. Analysis of variance revealed highly significant difference among genotypes for all the characters indicated that considerable amount of genetic variability was present in the experimental material which can be exploited for improvement of grain yield in pearl millet. Genotypic and phenotypic variances were recorded highest for biological yield per plant followed by dry fodder yield per plant and lowest for productive tillers per plant. High GCV and PCV were recorded for dry fodder yield per plant followed by biological yield per plant. Whereas, low for days to maturity. High estimates of heritability along with high genetic advance as per cent of mean was recorded for dry fodder yield per plant, productive tillers per plant and harvest index which indicated major role of additive gene action in the expression of these characters while high heritability along with moderate genetic advance as per cent of mean was recorded for grain yield per plant, plant height, panicle length and panicle girth which indicated these characters was mainly governed by non additive gene action.

Heavy Metal Toxicity and Tolerance in Plants with Special Reference to Cadmium: A Review
By: Dheera Sanadhya , Rajani Chauhan , Alfiya Bohra
Page No : 51-74
Abstract
Heavy metal (HM) toxicity is one of the major abiotic stresses leading to hazardous effects in plants; many of them are toxic even at very low concentration. Pollution of the biosphere with heavy metal has accelerated dramatically since the industrial revolution. A common consequence of HM toxicity is the excessive accumulation of Reactive Oxygen Species (ROS), which can cause peroxidation of lipids, oxidation of protein, inactivation of enzymes, DNA damage and/or interact with other vital constituents of the plant cells. Plants respond to avoid detrimental effects of HM in a variety of different ways such as restriction of uptake and transport of metals, plasma membrane exclusion, chelation and sequestration of heavy metals by ligands such as phytochelatins and metallothioneins, induction of heat shock proteins, biosynthesis of polyamines, and production of antioxidants (Enzymatic and non enzymatic). This review focuses on sources of HM and its toxicity with special reference to Cadmium, tolerance mechanism in plants and molecular approaches to overcome its deleterious effects on plants.

Microsatellite Markers: An Important DNA Fingerprinting Tool for Characterization of Crop Plants
By: Devendra Jain , Radheshyam Sharma , S.R. Maloo , Sharda Choudhary
Page No : 83-90
Abstract
Recent improvements in molecular analysis and genotyping methods lead to rapid expansion of the power of molecular markers. Genetic variation detection helps to researchers to understand the molecular basis of various biological phenomena in plants. In recent years, a new category of sophisticated molecular marker techniques has emerged, primarily derived from combination of PCR with non-arbitrary sequences of the genome. Microsatellites or simple sequence repeats (SSRs) or short tandem repeats (STRs) or simple sequence length polymorphism (SSLP) are tandem repeats of 2-6 nucleotides long DNA motifs. They appear to be ubiquitous in plant genomes, including organelles genome and involving repetitive as well as unique sequences. They are abundant, present in the whole genome and detect high levels of polymorphism, co-dominant and genome specific, although the frequency of microsatellites varies between species than any other molecular markers. Thus for characterization of biological traits, microsatellites or simple sequence repeats (SSRs) has been playing an increasing role in plant genetics and breeding owing to many desirable genetic attributes including hyper variability, multiallelic nature, co-dominant inheritance, reproducibility, relative abundance, extensive genomic coverage. Microsatellite markers are used for examination of genetic relationships between individuals, mapping of desirable genes, construction of saturated linkage maps, marker assisted selection, backcrosses, population genetics and phylogenetic studies. In this review we have tried to discuss recent progress in plants using microsatellite markers.

Abstract
Fresh and aged seeds of radish were treated with proline (5 mM and 10 mM), salicylic acid (50 mg/l and 100 mg/l) and water for 12 hr and 24 hr. In general, aged seeds showed less germination and activity of antioxidant enzymes as compared to fresh seeds. However, the seeds treatments increased the germination percentage and activity of antioxidant enzymes in both fresh and aged seeds as compared to control. The effect was more when treated with Proline followed by salicylic acid and water.

Page No : 97-99
Abstract
Promising cultivars and improved planting methods are of prime importance to realize the maximum potential of maize (Zea mays L.). The studies on the effect of different planting methods on crop growth and yield of different maize cultivars was conducted during spring season. The three methods of sowing (Ridge, Trench and Flat sowing) as main plots and four genotypes (PMH 1, PMH 2, Parkash and JH 3956) in sub plots were evaluated with split plot design. The plant height was significantly more with ridge sowing than trench and flat sowing. Days taken to 50 per cent silking under ridge sowing were significantly less than trench and flat sown crop. The grain yield was significantly more in ridge and trench sowing as compared to flat sowing. The ridge and trench method gave 10.2 and 8.0 per cent higher grain yield as compared to flat sowing. Higher yield in ridge and trench planted crop may be attributed to better access of roots to nutrient and water resulting in good plant growth. The plant and ear height; and days to 50 per cent silking was significantly higher in PMH 1 as compared to other hybrids. Similarly, PMH 1 (6810 kg/ha) being at par with JH 3956 (6712 kg/ha) recorded significantly higher mean grain yield than Parkash (5686 kg/ha) and PMH 2 (6478 kg/ha).

Abstract
SCoT marker has emerged as a superior system when compared to RAPD. Although SCoT is a random marker system like RAPD but it is able to give high reproducibility. Also, the annealing temperature of SCoT is higher than that of RAPD. This can be attributed to longer 18-mer primers of SCoT compared to 10-mer primers of RAPD. In some cultivars SCoT has emerged superior to ISSR when used for accessing genetic relationships. The information generated by Start Codon Targeted Polymorphism in valuable. Since it is a gene targeted marker system it produces highly specific and reliable data.

Abstract
Polyamines (PAs), Putrescine (Put), Spermidine (Spd) and Spermine (Spm) are small aliphatic amines that are widespread in living organisms. PA metabolism in higher plants is involved in both abiotic and biotic stresses. These are involved in many physiological processes, such as cell growth and development and also respond to diverse abiotic stress. This review, focus on the correlation between endogenous PA titers and physiological perturbations along with the protective role of various analogues of PAs against abiotic stresses. Polyamines level shifts in different ways depending on several factors, such as plant species, tolerance or sensitivity to stress, and duration of stress. Exogenously supplied PAs protects plants from abiotic stress, whereas transgenic plants overexpressing PA biosynthetic genes exhibited stress tolerance. On the other hand, loss-of-function mutant of PA biosynthetic genes, or decrease of PA titers, reported to decrease stress tolerance.

Abstract
Screening for drought tolerance has become a significant part of crop improvement programme in rainfed areas to cope up with water scarcity in context of climate change. Selective fertilization is a new technique to develop hybrids upon imposing selection pressure artificially during the events of pollen germination and fertilization. In the present study, we evaluated two coconut hybrids viz. Kerasree S.F and Keraganga S.F developed through selective fertilization for water use efficiency under 100% and 50% field capacity and were compared with their normal hybrids for various drought tolerance mechanisms. Results have shown that selectively fertilized hybrids varied significantly from their normal hybrids for relative water content, proline content and activity of enzymatic antioxidant catalase. Kerasree S.F be the most water use efficient genotype on account of maximum dry matter accumulation and lowest volume of cumulative water transpired.

By: M. L. Jakhar , Santosh Choudhary , R P Didel , Ganga Ram
Page No : 13-16
Abstract
Shoot apex and hypocotyl explants of seven coriander (Coriandrum sativum L.) genotypes were cultured on MS medium supplemented with varying concentrations of cytokinins and auxins. Profuse callus induction was observed in hypocotyls explants at 1.0mg /l 2,4-D and this callus remained potent for longer time. Shoot apex derived BAP (1.0 mg/l) callus was also subcultured on different concentrations of plant growth regulators. However, it did not regenerate in complete plant even after various manipulations. Shoot morphogenesis was observed in hypocotyls derived callus cultures upon subculture on 0.5 mg/l BAP. Genotype RCr-20 induced maximum de novo shoots from callus followed by RCr-446. De novo developed shoots from callus grown on the medium containing 0.5 mg/l NAA induced roots at the base and complete plants were obtained.

Page No : 21-25
Abstract
Obtaining intact genomic DNA of sufficiently high quality that is amplifiable using PCR from black pepper is a challenging task, as it is rich in polyphenolic compounds. Methods that are currently available recommend the use of young leaves which may not be available in all seasons. In this paper, a modified protocol of the CTAB method for the extraction of genomic DNA from mature leaves and spikes of black pepper is presented. This method employs higher concentrations of CTAB, NaCl, EDTA and PVP. Good yield of DNA ranging from 400 to 500 ng/?l with A260/280 ratio of 1.7 to 2.0 was obtained. The isolated DNA was successfully amplified by RAPD primers.

By: M.L. Jakhar , Rajdeep Mundiyara , S A Kerkhi , S Mishra
Page No : 39-47
Abstract
A study was conducted at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U. P.), during rabi 2010- 2011. Range, CV, heritability, genetic advance, correlation coefficient and path analysis were performed for yield and its contributing characters in 49 wheat genotypes. Analysis of variance for significant differences was among the all characters viz., days to 50 percent flowering, days to maturity, plant height, number of spikelets per spike, productive tillers per plant, ear length with awn, number of grains per spike, 1000 grain weight, and biological yield per plant, grain yield per plant, harvest index and gluten content. A broad range of variation was observed for plant height and biological yield per plant, number of grain per spike and test weight. Phenotypic variance value for most characters was closer than the corresponding genotypic variance value showing little environment effect on the expression of these characters. The estimated value of broad sense heritability was found between 45 percent (productive tillers per plant,) and 95 percent (gluten content). Heritability values were determined as 92 percent, 92 percent, 89 percent, 85 percent, 84 percent, 71 percent, 68 percent, and 67 percent, for plant height, days to maturity, test weight, days to 50 percent flowering, ear length with awn, harvest index, number of grains per spike, and grain yield per plant respectively. High heritability coupled with high genetic advance as percent over mean was observed for plant height, test weight, number of grain per spike and days to maturity suggesting selection for these traits would give good responses. The grain yield per plant exhibited highly significant and positive correlation with biological yield per plant, test weight, productive tillers per plant, and number of grains per spike, number of spikelets per spike, spike length with awn, plant height, and significant and positive correlation with harvest-index. It is suggested that these characters can be considered as selection criteria in improving the grain yield.

Physiological Growth - Yield Relationships in Wheat Genotypes Under Sowing Date Mediated Heat Stress
By: Radhika , SK Thind , NS Bains , P Chhunneja
Page No : 73-79
Abstract
Twenty five wheat genotypes were classified into two groups i.e. early and late maturing on the basis of their ear emergence and maturity under sowing date mediated heat stress conditions. The early maturing group genotypes were found superior for early emergence and it had spent maximum period of total life span to grainfilling under late sown conditions, but was found poorer in yield than other genotypes of late maturing group. The correlation of grain yield with days to ear emergence and maturity shifted from negative in late maturing group (LMG) to positive in early maturing group (EMG) under both timely and late sown conditions. All plant growth parameters (RGR, LAI, NAR) were adversely affected by temperature stress which finally reflected in yield reduction. The impact of this adversity could be clearly seen to a large extent in late maturing genotypes, However there was clear cut variation among the genotypes for late planting conditions. The measurement of growth parameters LAI, RGR and NAR is important because they are positively correlated to biomass production. Final yield had strong positive association with the NAR and LAI. Their significance becomes crucial particularly under stress environment.

The Role of Silicon to Increase Salt Tolerance in Red and White Varieties of Bean (Phaseolus vulgaris L.)
By: Parto Roshandel , Hadi Nosrati , Abdo-rahman Mohamadkhani
Page No : 81-90
Abstract
Silicon (Si) application is recently considered as a way to increase salt tolerance in crop plants. In the present study the effect of Si has been investigated in two varieties of Phaseolus vulgaris (red and white bean) subjected to salinity. 10-day-old seedlings of red and white beans were introduced to the treatments including: control, NaCl (50 mM), Si (0.5 or 1 mM) +NaCl (50 mM) over 4 weeks in the green house. After one month, the harvested plants were analyzed for dry weights of shoots and roots, total chlorophyll content, relative water content and electrolyte leakage of leaves, shoot and root Na+ and K+ concentrations. The results indicated salt stress significantly decreased the above parameters (p<0.05). Red bean plant was more sensitive (108% reduction in the biomass) to salt stress in comparison to white bean plant (72% decline in the biomass). The ameliorating effects of different levels of Si (0.5 or 1 mM) were significant (p<0.05) under salinity, and in some cases these effects were greater at Si 1 mM in comparison to 0.5 mM. Under salinity, the promotion effects of Si on biomass were more evident for the sensitive line- red bean (55% increment in comparison to salt stress alone) than that of in white bean. Data analysis of the current study suggests that Si increases salt tolerance in red bean by relatively blocking Na+ entrance but increasing of K+ maintenance in the shoots, increasing of relative water content and decreasing of electrolyte leakage in the leaves. More details are expressed and discussed in this paper.

Abstract
A comparative study of thirty six, S1 , S1 -OP-S1 and S1 -OP-OP progenies of pearl millet [Pennisetum glaucum (L.) R.Br. emends Stuntz] for green fodder yield over one season revealed highly significant differences among progenies for days to heading, plant height, tillers per plant, leaves per plant, 3rd leaf area, internode extrusion, leaf : stem ration, stem thickness and green fodder yield per plant. The genotypic and phenotypic coefficients of variation were more or less similar for all the characters. High (50-70 percent) to vary high (> 70 percent) heritability was coupled with high (> 50%) genetic advance as percentage of mean was observed for green fodder yield per plant in all three types of progenies, confirming that genotypic variance has contributed substantially to the total variance. Whereas, high heritability was coupled with medium to low was observed for. Based upon character association and path analysis, it may be concluded that plant height, tillers per plant and leaves per plant were the major green fodder yield component, because it has high positive significant association and positive direct effect on green fodder yield in all the three types of progenies. Based on the results of the per se performance of three progenies considering for various traits, the genotypes IP141, IP-196-1, IP-111-1, IP-181-1 and IP-204-1 were found to be superior for earliness, plant height, tillers per plant, leaves per plant, 3rd leaf area, stem thickness, leaf : stem ratio and green fodder yield per plant. Therefore, these progenies should be utilized in further breeding programme for developing superior varieties.

Abstract
Tomato is an important vegetable crop grown in India. It is affected with many fungal, bacterial and viral diseases. Early blight is one of the most important known fungal diseased caused by Alternaria solani. A experiment was evaluated in randomized Block design with nine treatment in three replication at the farm of Plant Pathology Department, College of Agriculture Nagpur during 2009-10. Eight fungicides viz. copper oxychloride (0.25%), carbendazim (0.1%), mancozeb (0.2%), zineb (0.15%), Captafol (0.2%), Thiophanate methyl (0.005%), Iprodione (0.2%) and Duter (0.2%) were tested against A. solani by using poisoned food technique in vitro. The data reveals significant differences as mean radial mycelial diameter over control. Minimum colony diameter (8.97mm) was recorded in mancozeb (0.1%) and highest (88.97%) percent inhibition growth. This treatment was significantly superior as compared to all other treatments. Significant differences were noticed on percent disease incidence after 1st, 2nd, 3 rd, 4th spray of different chemicals over control. Spraying of mancozeb (0.2%) at the interval recorded minimum PDI (22.18) and maximum percent disease control (32.29%) and it was found significantly superior over all other treatment. It was followed by carbendazim (0.1%) and copper oxychloride (0.25%) reading 28.22 and 24.85 percent disease control. The highest yield was obtained by the treatment mancozeb (0.25%) 18333 kg/ha followed by carbendazim ( 0.1%) 17916 kg/ha.

Performance of Mungbean Under Irrigated Conditions: Physiological Parameters Determining the Yield During Crop Growth
By: Pushp Sharma
Page No : 147-152
Abstract
Growth parameters like leaf area(LA), crop growth rate (CGR),relative growth rate(RGR) and net assimilation rate (NAR) were compared in four varieties of mungbean under subtropical conditions to identify growth limiting characters for efficient application of physiology breeding for higher yields. Analysis of yielding ability and growth pattern of mungbean genotypes procured from Asian vegetable research development centre (AVRDC) revealed significant differences in morphphysiological traits during crop growth. The maximum chlorophyll and leaf area was recorded at 60DAS. Peak flowering and pod development phase coincided with leaf area development. Significant differences in leaf characteristics existed for leaf weight ratio (LWR), leaf shoot ratio (LSR) and leaf area ratio (LAR) at 60 and 75 DAS whereas growth rates like net assimilation rate (NAR), crop growth rate (CGR) and relative growth rate (RGR) were high at 45-60DAS. Sources could adjust to some extent to higher requirement of its sink, indicating a strong inverse relationship between flower production and their subsequent shedding. NAR, CGR, SLA, LAR are the desirable traits to be exploited for higher productivity.

Page No : 157-170
Abstract
Garlic propagates only asexually leading to the absence of meiotic recombination. Garlic cultivars available for cultivation in India have arisen from the accumulation of somatic mutations in early cultivars. Present study intended to evaluate the genetic diversity of 96 accessions collected from major garlic growing states and two exotic accessions by using morphological traits to identify possible duplicate cultivars, and to assess genetic divergence. We assessed 15 morphological characters associated with leaves, bulbs, and bulbils of the garlic plant. Genetic divergence was calculated using the Jaccard coefficient; the cultivars were grouped using unweighted pair-group mean analysis. The average genetic divergence detected using the morphological characters was 2.30 (range, 0.45-4.70). Plant height and coat adhesion exhibited the highest divergence among the cultivars. Most of the cultivars revealed only slight differences, suggesting that these cultivars may be clones or have a high degree of affinity.

Abstract
Field experiment was conducted to evaluate the efficacy of some new insecticides against sucking insect pests viz., leafhopper, aphid and whitefly in okra. Three sprays of different concentrations of insecticides viz., Thiamethoxam 25 WG, Lambda cyhalothrin 5 EC and Triazophos 40 EC were made at 15 days interval on the okra variety Akola Bahar, sown at Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during Kharif 2012. All the treatments were found to be superior over the untreated control. Amongst the treatments tested, the cumulative effect of foliar spray of Thiamethoxam 25 WG @ 0.006 percent was effective against aphids followed by Lambda cyhalothrin 5 EC @ 0.004 percent, Thiamethoxam 25 WG @ 0.008 percent, Thiamethoxam 25 WG @ 0.009 percent, Lambda cyhalothrin 5 EC @ 0.005 percent, Triazophos 40 EC @ 0.025 percent, Triazophos 40 EC @ 0.031 percent, Lambda cyhalothrin 5 EC @ 0.006 percent and Triazophos 40 EC @ 0.04 percent. While, Thiamethoxam 25 WG @ 0.006 percent was effective against jassids population followed by Thiamethoxam 25 WG @ 0.008 percent, Thiamethoxam 25 WG @ 0.009 percent, Lambda cyhalothrin 5 EC @ 0.004 percent, Lambda cyhalothrin 5 EC @ 0.005 percent, Triazophos 40 EC @ 0.025 percent, Lambda cyhalothrin 5 EC @ 0.006 percent, Triazophos 40 EC @ 0.031 percent and Triazophos 40 EC @ 0.04 percent. Also, in case of whitefly the effective treatment recorded Thiamethoxam 25 WG @ 0.006 percent followed by the treatments Lambda cyhalothrin 5 EC @ 0.004 percent, Lambda cyhalothrin 5 EC @ 0.005 percent, Thiamethoxam 25 WG @ 0.008 percent, Triazophos 40 EC @ 0.025 percent, Lambda cyhalothrin 5 EC @ 0.006 percent, Thiamethoxam 25 WG @ 0.009 percent, Triazophos 40 EC @ 0.031 percent and Triazophos 40 EC @ 0.04 percent all at par with each other.

Effect of Temperature, Relative Humidity and pH on Mycelial Growth and Sporulation of Fusarium solani Causing Root Rot of Indian Aloe (Aloe barbadensis MILL.)
By: M. K. Jat , R. R. Ahir
Page No : 197-199
Abstract
Indian aloe (Aloe barbadensis Mill. = Aloe vera) is the oldest medicinal plant commonly known as Ghritkumaree. It is a coarse looking, perennial shallow rooted plant with a short stem, 30-60 cm high and can be grown even in dry lands under rainfed situation. During survey, Indian Aloe were found infected with Root rot caused by Fusarium solani causing severe damage at seedling stage both in the field of Jobner vicinity during Spring season 2011-12. The effect of different levels of temperature (15, 20, 25, 30 and 35o C), relative humidity (60, 70, 80, 90 and 100 percent) and pH (5.5, 6.0, 6.5, 7.0, 7.5, 8.0 and 8.5) on growth and sporulation of the pathogen were tested in vitro conditions. Maximum mycelial growth and sporulation were found at 250 C temperature (84.15 mm), 100 per cent relative humidity (88.50 mm) and maximum dry mycelial weight at 6.5 pH (270g).

Efficacy of Fungicidal Seed Treatment Against Seed Borne Altrnaria alternata Associated with Radish (Raphanus sativus) Seeds.
By: S C Jain , Rekha Kumawat , Paru Panwar
Page No : 201-203
Abstract
Radish (Raphaus sativus Linn.) is a very popular root crop throughout India. It is a quick growing crop. It is easily grown as a companion crop or other crop between rows of other vegetables. Seed borne Alternaria alternata reduce seed quality and quantity in terms of both chemical composition and weight. Different systemic and non-systemic fungicides were used as seed treatment against seed born Alternaria alternata in vitro. Mancozeb proved to be most effective in improving seed germination (82.00%) and vigor index (95.90%) by reducing pre-and post emergence mortality (2.00%) with less number of seedling showing symptoms followed by Vitavax, Bavistin, Topsin-M and Captan which were observed to be less effective.

Peer Review Policy
The practice of peer review is to ensure that only good science is published. It is an objective process at the heart of good scholarly publishing and is carried out by all reputable scientific journals. Our reviewers therefore play a vital role in maintaining the high standards of the and all manuscripts are peer reviewed following the procedure outlined below.
Initial manuscript evaluation
The Editors first evaluate all manuscripts. In some circumstances it is entirely feasible for an exceptional manuscript to be accepted at this stage. Those rejected at this stage are insufficiently original, have serious scientific flaws, have poor grammar or English language, or are outside the aims and scope of the journal. Those that meet the minimum criteria are passed on to experts for review.
Authors of manuscripts rejected at this stage will be informed within 2 weeks of receipt.
Type of Peer Review
The single blind review, where the reviewer remains anonymous to the authors throughout the process.
Each MS is reviewed by 3 independent reviewers
How the reviewer is selected
Reviewers are matched to the paper according to their expertise. Our reviewer database contains reviewer contact details together with their subject areas of interest, and this is constantly being updated.
Reviewer reports
Reviewers are asked to evaluate whether the manuscript:
Is original
Is methodologically sound
Follows appropriate ethical guidelines
Has results which are clearly presented and support the conclusions
Correctly references previous relevant work
Reviewers are not expected to correct or copy edit manuscripts. Language correction is not part of the peer review process. Reviewers are requested to refrain from giving their personal opinion in the "Reviewer blind comments to Author" section of their review on whether or not the paper should be published. Personal opinions can be expressed in the "Reviewer confidential comments to Editor" section.
How long does the peer review process take?
Typically the manuscript will be reviewed within 2-8 weeks. Should the reviewers' reports contradict one another or a report is unnecessarily delayed a further expert opinion will be sought. Revised manuscripts are usually returned to the Editors within 3 weeks and the Editors may request further advice from the reviewers at this time. The Editors may request more than one revision of a manuscript.
Final report
A final decision to accept or reject the manuscript will be sent to the author along with any recommendations made by the reviewers, and may include verbatim comments by the reviewers.
Editor's Decision is final
Reviewers advise the Editors, who are responsible for the final decision to accept or reject the article. The decision of the editor in chief is final
