Influence of Calcium on Alleviating NaCl-Induced Injury Effects in Arabidopsis thaliana Seedlings
外源钙降低拟南芥幼苗盐害效应

After sprayed with 5 mmol/L CaCl_2 solution, the seedlings of Arabidopsis thaliana were grown under 100 mmol/L NaCl stress. The decrease ranges of the chlorophyll content, the activities of superoxide dismutase(SOD), catalase(CAT)and peroxidase(POD)were less than those of the non-sprayed seedlings. The increase range of malondialdelehyde(MDA)content was lower than that of the non-sprayed seedlings. The results showed that spraying leaves with CaCl_2 solution could alleviate the salt injury effects induced by NaCl and improve the ability of various physiological activities in the A. thaliana leaves.
