plants are always exposed to vast aspects of either environmental biotic or abiotic stresses and those stresses affecting the plant growth and therefore crop production. molecular and physiological mechanisms influence plant resistance to environmental stresses, therefore the identification of these mechanisms can be an important step in challenging the damages. in this study, plant physiologic...

Nickel and cadmium are heavy metals with some hazards for plant metabolism. The impacts of nickel chloride (0, 400 and 800 μM) in the presence of vitamin B complex (0, 30 and 60 ml from pharmacy commercial stock) and the impacts of cadmium chloride (0, 100, 200, 300, 400, 500 and 600 μl from 100 µM stock) in pot and cadmium nitrate (0, 100, 200, 400, 800, 1600 and 3200 μl from 100 µM stock) 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...

mechanisms of tolerance to water deficiency stress for introducing sunflower hybrid was investigated by a two-factor experiment as a split plot design based on rcbd was at the research station in alborz province, hashtgerd region, iran in 2013. irrigation rates (irrigation after 50, 100 and 150 mm cumulative evaporation from class a evaporation pan) were considered in the main plots and sunflow...

Proline accumulation in NaCl-treated excised barley (Hordeum vulgare var Larker) leaves was studied. Leaves were treated by placing the cut end in NaCl solutions and allowing the salt to enter the leaf via the transpiration stream. Leaves treated this way maintained turgor while the sodium content increased and the osmotic potential decreased. Proline began accumulating after 12 hours and conti...

abstract to assay the effect of acetylsalicylic acid pretreatment on enhancement of yield and yield components of barley (reihan-03) under water stress condition, an experiment was conducted as a spilt-plot arrangement based on randomized complete block design with four replications at the research field of shahid bahonar university of kerman, iran, in 2012-2013. irrigation condition was arrang...

Excised bean (Phaseolus vulgaris) leaves were used to measure changes in proline content and proline metabolism during rehydration in the dark after the leaves had been incubated in the dark 24 hours in a wilted condition.The increase in nonprotein proline which occurs in wilted leaves stopped immediately upon rehydration, and thereafter levels of proline declined. The rate of decline and the f...
