Salinity is the most important environmental stress that reduces plants growth and yield. It has been shown that salicylic acid, as an endogenous signal, is responsible for inducing stress tolerance in plants. In this experiment, the effect of salicylic acid and sodium chloride on growth of bean (Phaseolus vulgaris) was studied. When bean plants were at two-leaf stage, they were sprayed by thre...
in this study proline content and activity of catalase (cat), and ascorbate peroxidase (apx) and level of lipid peroxidation in terms of malondialdehyde (mda) content were measured in transgenic tobacco (nicotiana tabacum cv. wisconsin), over expressing a δ-1-pyrroline-5-carboxylate synthase (p5cs) gene, and non transgenic plants as control. drought stress was applied using polyethylene glycol ...
Abstract Study of physiological reactions of recombinant inbreed lines (RILs) to drought stress could help to identify the actual drought tolerance mechanisms. In this view a field experiment was conducted to evaluate the effect of drought stress on chlorophyll content , leaf proline content, leaf length, leaf width, leaf area, peduncle length and plant height using 169 RILs, in the two separat...
in order to investigate the effect of different irrigation regimes on yield and leaf proline content of a spring isfahan local variety of safflower, a field experiment was conducted as split plot in randomized complete block design with three replications at the research station of shahrekord university in 2013-2014. the main factor consisted of four different irrigation regimes (irrigation aft...
Aims: This research has as objective to evaluate the effect of NaCl salt stress on African eggplant plant growth and determine implication accumulation Na+, proline soluble sugars reduction K+ in detrimental this species.
 Study Design: The experiment was laid out a Completely Randomized Design (CRD) having five treatments three replications.
 Place Duration Study: carried screening h...
This experiment was performed to study osmoregulators in sugar beet under salinity stress, and determine the best method for screening of tolerant and susceptible cultivars, in the greenhouse of Shahid Chamran University of Ahvaz during 2009-2010 growing season. Three sugar beet cultivars (BR1, Jolgeh & Rassoul) were grown under three salinity levels including control (Zero), 100 and 200 mM NaC...
To investigate the effect of herbicide Trifluralin and the role of magnetized water on enzymatic activities and content of proline and growth substances including gibberellin (GA3) and cytokinin (6- benzyl amino purine), an experiment was conducted using squash (Cucurbita pepo L. var. Shiraz Hybrid F1) seedlings. Four levels of trifluralin (0, 5, 15 and 25 ppm) and irrigation by distilled and m...
in order to determine the genetics of barley lines for freezing resistance based on crown survival percentage an experiment was carried out as a split plot design on the basis of randomized complete blocks with two replications. forty barley lines were assigned in subplots and five freezing temperatures (-8, -11, -13, -15 and -17 ˚с) were allocated in main plots. the results showed significant ...
Freshly harvested tomato fruit (Solanum lycopersicum) were pre-treated with 0, 50, and 100 µM prohexadione-calcium (Pro-Ca) and then stored at 1 °C for 21 days to investigate the effect of Pro-Ca treatment on electrolyte leakage (EL), malondialdehyde (MDA), proline and total phenols contents, and activity of phenylalanine ammonia-lyase (PAL) in relation to chilling injury (CI).Treatment with Pr...
The influence of silicon (Si, 3 mM), sodium chloride (NaCl, 135 mM), and Si, 3 mM + NaCl, 135 mM supply on chlorophyll content, photosynthetic activity (CO2 -fixation), the concentration of malondialdehyde (MDA) and H2O2, activities of superoxide dismutase (SOD), catalase (CAT) enzymes, free proline and protein contents were studied in maize seedlings leaves after two month of treatments. The r...
