| 摘 要： | 用5mmol／L CaCl2喷叶后的拟南芥幼苗，在100mmol／L NaCl胁迫下，SOD、CAT和POD的活性以及叶绿素含量降低幅度明显低于对照，MDA含量增加幅度显著低于对照，由此表明钙与拟南芥幼苗盐害效应的降低有关。

| Abstract: | 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. |
