摘　　要：以鲁单981和强盛1号玉米杂交种为供试材料,采用酶活性测定技术,初步研究了淹水对玉米幼苗抗氧化酶系统的影响。结果表明,淹水处理后,在取样时间内鲁单981和强盛1号的CAT活性增强,但品种之间有差异;POD和SOD的活性升高,且品种间差异不大。CAT、POD和SOD活性的变化可能与玉米对淹水的抗性有一定的关系。Two maize hybrids of Ludan-981 and Qiangsheng-1 were used as the test materials,and the influence of waterlogging on the antioxidant enzyme system of maize was studied by using assay of enzyme activities.The results showed that CAT activity increased during the course of sampling both in Ludan-981 and in Qiangsheng-1 after treated with waterlogging,but there were some differences between the two varieties.Waterlogging could increase POD and SOD activities,and there was little differences between varieties.Therefore,we concluded that the activity changes of CAT,POD and SOD may be related to waterlogging resistance of maize.
