| 摘 要： | 朱砂叶螨危害豇豆幼苗后，叶绿体内与活性氧代谢有关的酶SOD、ASP活性及同工酶均受到不同程度的影响。(1)受害2～8d，SOD活性与对照相比均升高，差异显著。不同虫口密度之间在4d时SOD活性差异显著；(2)在危害期内，随着危害时间的延长ASP活性显著升高，且不同虫口密度之间差异极显著，虫口密度越大，ASP活性越高；(3)SOD同工酶谱带显示，随着危害程度的加强，一些分子量较大的同工酶谱带亦加强。

| Abstract: | The activities of SOD, ASP and SOD isoenzymes have been studied in cowpea (Vigna sinensis)seedling leaves damaged by carmine spider mite (Tetranychus cinnabarinus). The results are as follows:(1) 2~8 d after treatment, the SOD activity increases remarkably, there is a significant difference (P<(0.05)) compared with control group;(2) The ASP activity increased (P<0.01) with damaged days and increasing densities;(3) The SOD had no new isoenzymes induced, but the activities of two SOD isoenzymes enhanced. |
