Abstract

Salinity is a major environmental stress that affects the crop yields and the pea plants are high sensitive to salt stress. Salinity through oxidative stress damage cell structures, and antioxidants by eliminating free radicals increase tolerance to these stresses. In this research, effects of salt stress and leaf spray with ascorbic acid on growth parameters, photosynthetic pigments, antioxidant enzyme activities and lipid peroxidation on chickpea (Cicer arietinum L.) were investigated. The experiment is conducted as a factorial in a completely random design with three replications in greenhouse conditions. Salt stress has been applied by 0, 50, 100 mM NaCl solution and foliar were treatment by ascorbic acid solution 0, 3 and 6 mM in 3-5 leave stage. plants exposure to sodium chloride, were showed decrease in growth parameters and content of photosynthetic pigments in comparison with control plants, But the activity of catalase, superoxide dismutase enzymes and the content of proline and lipid peroxidation were increased. In plants exposed to sodium chloride and ascorbic acid, growth parameters, photosynthetic pigments were higher than plants only exposed to sodium chloride, although the lipid peroxidation and activity of catalase and superoxide dismutase enzymes and the content of proline were decreased. The results showed that spraying of ascorbic acid (as an antioxidant) is caused tolerance to salt stress and decreased of side effects of sodium chloride in Cicer arietinumm L.
