Abstract
The germination rate,germination vigor,MDA content and SOD activity of the Chinese cabbage treated by SNP,an exogenous nitric oxide donor,at the different concentration under 150 mmol/L NaCl stress were studied.The results showed that moderate concentration could enhance germination rate,germination vigor,reduced MDA content and increased SOD activity of the cabbage seedling at 4-leaf stage.However,excess concentration of SNP brought stress to cabbage,such as reduced germination rate and germination vigor,increased MDA content and reduced SOD activity in seedling.
