Abstract

In this article, the effect of SODMC on coldresistance of rice seedlings was investigated. The rice was treated with 2.5 mg/L SODMC by the way of soaking and spraying. The results are as follows: SODMC can keep the high activity of SOD and high Vc content of rice seedlings after chilling stress; SODMC can decrease the level of membrane lipid peroxidation and relative conductivity that caused by chilling stress; SODMC can increase activity of some isoenzymes. It seemes that it can initiate corresponding gene's expression, then improve the coldresistance of rice seedlings.
