Abstract [Objective] To discuss effects of drought stress on POD， CAT activity in wheat during germination period. [Method] Yunong 51， Zhoumai 22， Jimai 19 and Huaimai 22 were lected as experimental materials and cultured under drought stress simulated by different concentrations of PEG6000， the activity of POD and CAT was determined. [Result] The results showed that POD and CAT activity in wheat during generation period incread gradually under stress of 5% and 15% PEG6000 from 0 h to 120 h； POD and CAT activity in wheat under stress of 15% PEG6000 incread more compared with that under stress of 5% PEG6000； And that POD and CAT activity in wheat under stress of 25% and 35% PEG6000 incread first and then decread. Stress duration significantly affected the activity of POD and CAT in wheat during generation period. [Conclusion] The study can provide theoretical basis for wheat breeding.fall什么意思
