In order to study the effects of salt stress and leaf feeding by ascorbic acid on antioxidant enzyme activity, proline accumulation and lipid peroxidation on leaves and roots of Brassica napus L. cvs. Okapi, an experiment was conducted as a factorial in a completely random design with three replications. Plants were exposed to salt stresses by NaCl solution (200 mM) and foliar were treated by a...
effects of salinity and drought on growth, contents of proline, malondialdehyde (mda), proteinand activity of antioxidative enzymes were studied in two trigonella species. seeds andexplants of t. foenum-graecum and t. aphanoneura were grown on murashige and skoogmedium (ms) complemented with iso-osmotic concentrations of nacl (0, 100, 150 mm) andmannitol (0, 180, 275 mm). growth and relative wa...
The application of exogenous proline and glycinebetaine (betaine) confers salt tolerance on plants under salt stress. The effects of exogenous proline and betaine on apoplastic flow in rice plants under saline conditions were investigated using trisodium-8-hydroxy-1,3,6-pyrenetrisulphonic acid (PTS), an apoplastic tracer. Rice plants took up more PTS under light conditions than under dark condi...

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...
in order to study the effects of pgpr application methods on proline and soluble sugars content of yarrow (achillea millefolium l.) under drought stress conditionsan experiment was performed at islamic azad university, yadegar-e-imam khomeini (rah) shahre-rey branch. this experiment was carried out in a split plot arrangement with randomized complete block design in three replications. experime...
breeding medics species to drought and salinity tolerant can play an important role in herb production and pasture rehabilitation. with the aim of study of the performance of annual burr medics under drought and salinity stresses, a pot study was conducted with factorial arrangement of treatments in a randomized complete block design in shiraz university. sown seeds were two types (threshed an...
Heavy metals are a major environmental problem and have caused serious concerns because of characteristics of carcinogenesis, non-degradability and biological accumulation. Major part of this material is absorbed by plants and leads to inactivation of some enzyme, decreased protein production and disrupting variety of reactions and many cellular functions and growth and development cessation. T...
In this study, the effect of spraying of Zinc oxide nanoparticles at three concentrations (0, 1000 and 2000 ppm) on the response of Capsicum annuum L. to different levels of salinity (0, 25, 50 and 75 mM NaCl) was evaluated. The experiment was carried out as factorial based on randomized complete block design with four replications in pot culture conditions. The high concentration of salt and Z...
In vitro production is one of the fast and low-cost methods for mass propagation of horticultural crops. But, in vitro plantlets are more sensitive than others and need more adaptation against climatological factors. In order to investigate the symbiosis effects of two species of mycorrhizal fungi on growth and yield of sweet pepper (Capsicum annum L.) cv Inspiration, under drought-stress condi...
