Abstract
2 Abstract: Drought stress is one of the major abiotic stresses in agriculture worldwide. This study was carried out to investigate the effect of sodium niroprusside (SNP), putrescine (Put) and glycine betaine (GB) on alleviation of drought stress in cotton plant. The cotton plants pre-treated with three concentrations of SNP (0.05, 0.1 and 1 mM), Put (200, 400 and 600 ppm) or GB (400, 600 and 800 ppm) then exposed to drought stress. In general, the drought stress reduced the growth characters, yield characters, pigments, total soluble sugars, total free amino acids, total phenols, total soluble proteins and catalase activity, while increased proline content, total antioxidant capacity and peroxidase activity in comparison with control. The results showed that pretreatment of cotton plants under drought stress with SNP, Put or GB caused enhancement of growth and yield characters and increasing of pigments content, total soluble sugars, proline content, total free amino acids, total phenols, total soluble proteins, total antioxidant capacity and antioxidant enzyme activities. The optimum concentration of SNP, Put and GB to alleviate the drought stress in cotton plant was 0.05 mM, 600 ppm and 800 ppm, respectively. Finally, it can be concluded that foliar application of SNP, Put or GB could improve the drought tolerance of cotton plants.
