In this study, Lythrum salicaria plant was tested in hydroponic culture to demonstrate its zinc accumulating capacity and tolerance to different zinc levels. Lythrum salicaria seedlings were grown in 10% Hoagland solution containing 0, 5, 10, 20, 30, 40, 50, 75, and 100 mg/L zinc, and 30 mg/L zinc with different pH levels (5, 6, and 7). Following this, the seedlings were harvested after 1st, 2nd, 4th and 7th days. Zinc caused significant decreases in the relative values of the mean root-shoot length and fresh weight of the plant (92 to 75%; 100 to 92%; 64.2 to 41.

This study was carried out to investigate the ameliorative effects of salt pretreatment against B toxicity in two sunflower cultivars (Helianthus annuus L. ‘Sanbro’ and ‘Tarsan-1018’) differing in salt tolerance. Seedlings were grown in perlite with modified half-strength Hoagland’s solution for 15 days and then they were divided into two groups: salt-pretreated (75 mM NaCl for 5 days) and B-treated (control, 2, 4, and 8 mM B for 10 days). In both cultivars, the biomass of root and shoot decreased depending on B accumulation, especially at 8 mM.

This paper presents the experimental results of the effect of microorganism fertilizer (MF) on growth, yield and accumulation of Cu in lettuce grown on soil contaminated by Cu. The results show that applying MF on soil that has a Cu content of 17.03-106.4 ppm has a positive affect on the height, fresh weight, total chlorophyll content and catalase activity of lettuce grown on that soil.

An experiment was conducted in rabi season during 2012-2013 and 2013- 2014 to find out the effect of cereal crops (Wheat, Oat, Barley) and cutting schedule on forage and grain yield. The study revealed the maximum chlorophyll accumulation in Barley and wheat during initial stage at 95 DAS and wheat and barley during reproductive stage at 30 DAS. Cutting at 50 DAS is proved beneficial on chlorophyll accumulation. Photosynthetic rate were maximum in wheat at 90 DAS.

Water deficit is one of the major abiotic stresses which adversely affect the crop growth and yield. Moisture stress induce the metabolic functions, such as reduced synthesis of photosynthetic pigments, accumulation of osmoprotectants like proline, decline in the Chlorophyll stability and alterations in physiological parameters. The Field experiment was conducted at Agricultural College and Research Institute, Madurai during summer season 2016 with the variety of SVPR - 4.

Present investigation was carried out in the rainout shelter at Student Instructional Farm (SIF), Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) during Kharif (wet season) 2015 and 2016. Experiments were laid out in randomized block design with 3 replications, one variety i.e. Swarna Sub 1and nine foliar treatments. Rice plants were exposed to drought at 60 DAT for 15 days by holding irrigation during drought treatment. During drought treatment soil moisture tension of the field was ranged from 60-80 kPa.

Phytyl residues are the common side chains of chlorophyll (Chl) and tocopherols. Geranylgeranyl reductase (GGR), which is encoded by CHLP gene, is responsible for phytyl biosynthesis. The light-harvesting like protein LIL3 was suggested to be required for stability of GGR and protochlorophyllide oxidoreductase in Arabidopsis.

Responses of 4 cultivars of rice viz. NDR-8002, TCA-48, IR-42 and BPT 5204 to varying levels of moisture deficit stress at flowering stage were assessed in the plastic tubs for their relative tolerance to drought. Moisture deficit adversely affected the apparent translocation rate, relative leaf water content, total chlorophyll content and total soluble carbohydrate content, while proline accumulation enhanced irrespective of varieties. Grain yield decreased conspicuously in all the varieties in response to water stress.

Nigella (Nigella sativa L.) is a spice crop that belongs to Ranunculaceae family. The seeds or grains resembling onion seed, are used both as spice and medicine. In Malda district of WB, this crop do not cultivated earlier time but recent 2 to 3 Years it is introduced as a new seed spices which opens new avenues for the farmers by not only the choice of crops but also improve their revenue from the land.

Water stress was imposed on four varieties of Indian mustard viz., PusaBahar, Varuna, Pusa Jai Kisan and PusaAgraniby withholding irrigation at 3 different stages of crop growth i.e., vegetative, reproductive and pod-filling stage. The maximum impact of water stress on total chlorophyll content was observed at pod filling stage. The total chlorophyll content decreased a maximum in cv. PusaAgrani and minimum in Pua Jai Kisan. Proline accumulation increased in all the test verities and maximum accumulation was observed at reproductive stage.

Invasive species (weeds) contribute to great losses in crop productivity, and one of the strategies for controlling their distribution in the field involves the use of herbicides. However, the development of new formulations for the control of weeds is challenged by environmental issues, increases in the resistance of weeds to herbicides, and poor selectivity of herbicides towards invasive species.

In addition, although plants substantially accumulated the UV-B-absorbing compounds, the photosynthetic process might not be adequately protected from UV-B radiation.

In this study, the inducible function of sodium nitroprusside (SNP, a nitric oxide donor) was evaluated based on the changes in some biochemical characteristics of mungbean (Vigna radiata (L.) Wilczek cv. DX208) involving resistance to cowpea aphid (Aphis craccivora Koch). SNP treatment was sufficient to increase content of chlorophylls, reduced aphid-infested damage, accumulated biosynthesis of antioxidants such as phenolic compounds and flavonoids in mungbean plants attacked by A. craccivora.
