抗寒性不同的水稻幼苗在低温处理前后MDH、SOD、POX和EST同工酶的变化

A Study on the changes of MDH, SOD, POX and EST isozymes of rice seedlings with different Cold resistanc before and after low temperature treatment

抗寒性不同的水稻幼苗，经人工低温（０—４℃）处理后，ＭＤＨ、ＳＯＤ、ＰＯＸ和ＥＳＴ同工酶的变化明显不同。说明同工酶分析可能成为鉴定水稻幼苗抗寒能力的新的有效方法。

The changes of MDH.SOD. POX and EST isozymes of rice Seedlings which are different in resistance to Cold differ obviously from one another before and after low temperature (0 - 4℃ ) treatment. This suggests that analysis of isozymes may become a new effective method for evaluating the cold resistance of rice seedlings.
