In order to investigate the effect of different ratios of ammonium: nitrate on the photosynthesis and fatty acid composition in canola (Brassica napus L.) under different levels of salinity, an experiment was conducted as a factorial based on complete randomize design at Agricultural Research Center in East Azerbaijan in 2010. The first factor was different ratios of nitrogen sources to ammoniu...

An experiment was carried out to investigate the effect of progressing water deficit stress on leaf water relation parameters and compatible solutes at different phenological stages. Completely randomized design including four phenological stages (as drought stress treatments) was used. Each treatment had five replicates. Variables measured were osmotic potential (&PsiS), relative water content...

This research were carried out to evaluate physiological responses of wheat cultivars to salt stress using a factorial experiment cultivars (Chamran, Karchia66, Ghods, Tjan, Atrak, Roshan, Kavir, Mahoti, Alvand, Mahdavi, Niknejad, Biston, Sardari, Felat, Tabasi, Sorkhtokhm, Golestan, Darab2, Azadi) at seedling growth stage in two salinity levels (0 as control and 10 ds m-2 NaCl solution) in Isl...

The effects of irrigation, dry farming and drought treatments on the activities of antioxidant enzymes including superoxide dismutase, ascorbate peroxidase, catalase and peroxidase in barley leaves at different generative growth stages under field conditions were investigated. Three senescence parameters including chlorophyll, total soluble protein and rubisco large subunit protein loss, were a...

This experiment was conducted in 2010 in order to study the effect of drought stress on proline, soluble carbohydrates, relative water content, concentration of potassium and sodium of leaf, electrolytes leakage from leaves and grain yield of spring rapeseed cultivars in Research Greenhouse of Yasouj University, Yasouj, Iran. The experiment was factorial, based on completely randomized design w...
