hydroponic experiments were performed to exam the dynamic change of endogenous proline in rice seedlings exposed to potassium chromate chromium (vi) or chromium nitrate chromium (iii). although accumulation of both chromium species in rice seedlings was obvious, more chromium was detected in plant tissues of rice seedlings exposed to chromium (iii) than those in chromium (vi), majority being in...

This study was conducted to evaluate changes in antioxidants, free proline, relative water content and determination of root colonization of four commercial wheat (Triticum aestivum L.) cultivars (Azar2, Darab2, Shiraz, and Falat) inoculated with the fungus Glomus intraradices, under four water regimes of 100, 75, 50, and 25% of field capacity in the year 2010 at the School of Agriculture, Shir...

This study was carried out to appraise whether or not the exogenous application of a potential osmoprotectant, proline, could ameliorate the adverse effects of drought stress on maize seed and seed oil composition, as well as oil antioxidant activity. Water stress reduced the kernel sugar, oil, protein and moisture contents and most of the seed macro- and micro-elements analyzed in both maize c...

cold stress is one of the limiting factors in production of greenhouse vegetables. chemicals offer useful approach to reduce low temperature-induced damages. this study was conducted to evaluate the effect of foliar application of methyl jasmonate (meja) at concentrations of 0 (control), 50, 100, 200 µm) on electrolyte leakage (el), relative water content (rwc), soluble carbohydrates, proline, ...

The 45-days-old seedlings of drought resistant (N-22, CR143-2-2) and susceptible rice (Oryza sativa L.) genotypes (Panidhan, Pusa-169) were subjected to osmotic stress in PEG-6000 solution of -10 and -16 bar and the relative water content (RWC), proline content, and pyrroline-5-carboxylate synthetase (P5CS) activity and its P5CS expression were studied. A gradual decrease in RWC was observed in...

Indian mustard [Brassica juncea (L.) Czern & Coss] is one of the most important oilseed crops worldwide yet drought and salinity stress significantly reduced its growth yield. The research was carried out in order to test effect on osmoprotectants (total soluble sugars, proline), antioxidant molecules (ascorbate, ?-tocopherol) ionic content from dry sample leaves introgression lines varieti...

introduction: salinity is the most significant abiotic factor limiting crop productivity and several physiological responses, including modification of ion balance, water status, mineral nutrition, stomatal behavior, photosynthetic efficiency and so on. the gf677 (prunuspersica×prunusamygdalus) is widelyusedas rootstock for peach and almond. it is mainly used as a rootstock because of its resis...

the impacts of salicylic acid and silicon on some physiological parameters of maize seedlings in the presence ofcadmium (100 μm) were investigated. inhibitory effects of cadmium on seedling growth resulted in reduced shoot and root fresh weight, low percentage of relative water content, low chlorophyll, free proline and soluble sugars contents and a low rate of lipid peroxidation. results indic...
