Abstract 

Deproteinised Juice (DPJ) used as remedy to induce drought tolerance by reducing rate of transpiration. Wheat (Triticum aestivum. L) plants were cultivated in pots consisting of red soil and treated with the DPJ and compared with control. Proline determination elucidated that the stress in plants declined favourably due to soil exogenous application of DPJ. There was favourable reduction of proline content by the treatment of Basella alba L. DPJ in wheat plants. Also there was increase in the length and number of leaves of the plants in wheat plants. The yield of proline is compared with another crops of Bajra, Eleusine, and Jowar. The DPJ made from different leguminous and non leguminous forages also were treated to these crops for comparison. The effect of another DPJ of weed plant of Cassia tora L utilised for the growth of Eleusine coracana L plants. The DPJ effected on the unfavourable increase in proline content and decrease in stomatal aperture size in Eleucine coracana L. leaves using a light microscope as compared with control. There was the reduction in the development of the stomata by DPJ efficacy. However there was no significant change in stomatal index.

Abstract 

Detailed studies have confirmed the role of Abscisic acid in various biological phenomena and its role under cold stress, in particular has been well established. Since ABA levels donot accumulate to appreciable levels in all plants, its exogenous application has been found to alleviate hazards of cold stress substantially. Latest reports suggest the role of ABA as a signaling molecule under cold stress.

Abstract 

A study was carried on to assess the level of drought stress effect on the morphological and physiological traits of cowpea in drought threaten region Botswana. The results disclose that the twenty cowpea genotypes under studied growth parameters (plant height, leave area, biomass, relative water content, gaseous exchange, chlorophyll content, and dry matter content) were drastically reduced. The result prove that biomass mean production (BMP) classified the 20 cowpea genotypes as: BCA001 and BCA003 (highly tolerant); BCA002, BCA006, BCA009, BCA016, BCA011 and BCA019 (drought tolerant); BCA004, BCA015 and BCA017 (moderate tolerant); BCA020, BCA014, BCA013, BCA012, BCA007, BCA008, BCA010, BCA005 & BCA013 (sensitive). Relationship between BMP and gas exchanges [net photosynthesis (R2 = 0.0345), stomata conductance (R2 = 0.040), transpiration (R2 = 0.006)] was rather poor, thereby showing that the variability of cowpea genotypes for drought tolerance based on BMP index is the differences in gaseous exchange. This research concludes that Using biomass yield under well water (BYp) and drought stress conditions (BYs), Mean Biomass Production (BMP) is the most suitable index for drought tolerance selection while plant physiological parameters (chlorophyll content and gaseous exchange) was not feasible for classification of drought stress tolerant.

Abstract 

Heavy metal contamination is the major problem spreading worldwide as non biodegradable pollutant. The toxicity of metals creates threat for primary and secondary consumers in environment and reaches to the top level in the ecosystem through food chain. Cadmium and lead being toxic heavy metals have been assessed for retarding growth, decreased photosynthesis in plants. Therefore, the present study was planned to observe the uptake of cadmium and lead in roots of Moringa oleifera seedlings in metal contaminated soil. In response, phytotoxic effect of different concentrations of CdCl2 and Pb (NO3)2 on plant root growth, ratio of shoot and root length, number of branches and leaves per seedling, tolerance and β-carotene was observed. The metal treatment was applied to germinating seeds in pots containing soil and study lasted 30 days. The study revealed maximum uptake of lead in roots as compared to cadmium. According to present analysis inhibition in root length was appeared with increasing concentration of both metals. Seedlings were found more susceptible to increasing cadmium concentrations in comparison to lead, whereas, 3 mM and 5 mM lead showed quite variation in results. Elevated level of non-enzymatic β-carotene antioxidant was recorded significantly. Constant survivability of metal hyperaccumulating Moringa oleifera seedlings shows tolerance under heavy metal stress.

Abstract: 

Chickpea (Cicer arietinum L.) is one of the most important protein-rich cool season food legumes grown under rainfed condition. India is the largest producer of chickpea in the world and the crop is being affected through climate change. Among the abiotic stresses, drought and heat are the most important constraints to chickpea production globally. A pot experiment was conducted in the month of November 2009 and 2010 at Agricultural Research Farm, Janta Vedic College, Baraut, Uttar Pradesh to evaluate chickpea genotypes viz. kabuli (Pusa 1088 and Pusa 1053) and desi (Pusa 1103 and Pusa 547) under varied temperature regimes. Data resulted that pod formation depends on the temperature occurring pre and during flowering period, but seeds/pod and weight/seed were highly susceptible to high temperature stress. Pusa-547 exhibited 17.25% more TDMP than Pusa-1088 followed by Pusa 1053(8.65%) and Pusa-1103(4.78%) throughout the study. Pusa-547 produced more number of pods/plant (26.28%) in comparison to others. Pusa-1053 produced bolder grains (1.6%) than Pusa-1088 followed by Pusa-1103(20.80%) and Pusa-547(21.17%) and resulted more biological yield in Pusa-547. Thus, Pusa-547 showed more significant results in all yield traits than other chickpea genotypes. As the result shows that the desi genotypes may have a better ability to tolerate high temperature stress than kabuli genotypes.














Abstract: Syrian local, White candela, Red mezzo, Black karabolat, and Red Candela radish cultivarsirrigated by either wastewater contaminated River, Dam water, and Well water. In addition to wastewater contaminated river reclaimed by alum, clay soil, peat moss, wastewater sheep manure, Fulvic- Humic acids, wood coal, or ethylamine tetra acetic acid (EDTA). Our intention was to evaluate the radish consumption validity of urban grown radish.The best water type applied for radish growth was wastewater reclaimed with ethyldiaminetetra acetic acid (EDTA). Subsequently, the applied reclamation methods efficiencies can be categorized as the following: EDTA> WWe >WWCO >WWF-H >WWA > WWS> WWP > WWCL> WWD> WW. The highest Pb accumulation was confined to plants irrigated with contaminated river (380.16μg.g-1) which was to (148.39μg.g-1) by alum reclamation. Cheating abilities could be put in the below sequence order: WWA> WWF-H > WWEDTA > WWS > WWP > WWCO > WWCL. The highest Cd accumulations were detected in roots of well water irrigated plants. The highest free indole- 3-acetic acid (IAA) and GA3 contents of leaves were observed in WWD. The obtained results exhibited that WW contained the highest free Abscisic acid (ABA). Stomata responses manifested that the most potent response was confined to WWe treatment. The best cultivar was white candela as compared to other investigated. Subsequently, radish cultivars can be put according to their potency in the following order: white candela > red candela> black Karabolat > red mezzo > Syrian local.

Abstract 

Our food contains macro and micro elements that provide required nutrition to the body. Of all then utritive elements, iron (Fe) and calcium (Ca) play a significant role in maintaining the physiological balance in the body. For the past two decades, plant tissue culture techniques have emerged as a strong method for increasing the productivity and nutrients of food crops. In the present study, the effect of varying concentrations of the plant growth regulators (PGRs) viz. 2,4-D, NAA, IAA, BAP, kinetin and zeatin on the iron (Fe) and calcium (Ca) content of the in vitro Potato (Solanum tuberosum L.) plantlets was studied as potato is the most widely eaten vegetable all over the world. Kinetin proved to be the best plant growth regulator in increasing the iron and calcium content of the in vitro plantlets as compared to other plant growth regulators. The iron and calcium contents were analysed by Inductive Coupling Plasma Atomic Emission Spectroscopy.

Abstract 

An experiment was carried out to study the effect of foliar application of potassium on growth and water stress. The results reveal that all the growth biochemical constituents of Stevia rebaudiana plants under parameters (plant height, leaf area index, biomass, relative water content) were drastically reduced and the biochemicals viz. total amino acid, protein and nitrogen content were also affected in response to water deficit. However foliar application of K had a positive effect on growth of Stevia rebaudiana plants and also maintained optimum biochemicals. Results prove that foliar application of KNO3 under water deficit conditions can be effective in promoting the growth performance with enhanced biochemicals. This research concludes to increase the tolerance capacity of Stevia rebaudiana and may prove beneficial for commercial cultivation and management of Stevia rebaudiana  in water scarce regions hence promoting its quality and quantity characteristics.
