Abstract

In this study,Hoagland solution culture method was applied to investigate the dynamic of several physical and biochemical indexes,such as the content of proline,soluble proteins and MDA in the leaves of corn seedlings under different NaCl stress pressure.The results showed that with the increase of salt concentration,the SOD activity,the proline content and MDA content increased gradually,and the soluble protein content increased firstly,then decreased slowly.The contents of MDA,proline,soluble proteins and SOD activities can be taken as the physiologic index of resistance to salt stress of corn.
