drought stress is the most important factor that reduces yield in crops including chickpea and causes some changes in seed composition. this study was performed in order to evaluate the effects of drought stress and starter nitrogen fertilizer on four cultivars of chickpea. experiment was performed in a split-factorial using randomized complete block design with three replications. drought stre...

As an important antioxidant for plants and humans, L-ascorbic acid (AsA, vitamin C) can scavenge reactive oxygen species (ROS) and can be regenerated from its oxidized form in a reaction catalyzed by dehydroascorbate reductase (DHAR). To analyse the effect of overexpressing DHAR on tomato (Solanum lycopersicum), an expression vector containing potato cytosolic DHAR (DHAR1) or chloroplastic DHAR...

In this study, the alleviation effect of exogenous calcium (Ca) against cadmium (Cd) toxicity to growth, photosynthetic characteristics, antioxidant properties, and absorption of nutrients was explored in nutrient solution-cultured garlic seedlings. The results indicated that Cd significantly inhibited the growth of garlic seedlings as well as reduced the chlorophyll content, net photosynthetic...

in order to evaluate the effects of foliar application of methanol on some physiological characteristics of chickpea under drought stress, an experiment was conducted as a factorial based on completely randomized design with three replications in 2011 at the recearch center of plant for sciences in ferdowsi university of mashhad. the first factor was different levels of methanol including, 0 (c...

Water retaining agent (WRA) is widely used for soil erosion control and agricultural water saving. Here, we evaluated the effects of the combination of beneficial soil bacterium Bacillus amyloliquefaciens strain GB03 and WRA (the compound is super absorbent hydrogels) on drought tolerance of perennial ryegrass (Lolium perenne L.). Seedlings were subjected to natural drought for maximum 20 days ...
