Abstract
The study was conducted in a nutrient solution to investigate the effects of Ca2+ on growth and active oxygen metabolism of cucumber seedlings induced by exogenous nitric oxide under the 50 mmol/L NaCl stress.The results show that plasma membrane Ca2+ channel blockers La3+ block the effects on growth and active oxygen metabolism induced by exogenous nitric oxide.Exogenous nitric oxide or Ca2+ alleviate the injury to seedlings under the 50 mmol/L NaCl stress significantly,and the seedling growth,activities of SOD,POD and CAT are increased and the rate of O-·2 production,contents of MDA and H2O2 are decreased.These results indicate the La3+ blocks those effects induced by exogenous nitric oxide under the NaCl stress,and Ca2+ might play an important role in growth and active oxygen metabolism induced by exogenous nitric oxide.The effect of nitric oxide here depends on the content of Ca2+ in cytoplasm.
