| 摘 要： | 研究了水稻植株受白背飞虱和褐飞虱为害后体内的活性氧清除系统主要酶活性的变化动态。结果表明，受白背飞虱为害后，稻株体内的超氧化物歧化酶（SOD）活性增加、过氧化氢酶（catalase）活性下降，过氧化物酶（POD）活性变化在抗虫和感虫材料中有差异，前者活性增加，后者下降；受褐飞虱为害后，SOD活性增加，catalase和POD活性在抗虫材料中下降，而在感虫材料中增加；其为害造成的抗虫材料SOD活性增长率和感虫材料catalase活性下降率均比白背飞虱高。这和褐飞虱的取食量明显高于白背飞虱的取食量趋势相似。

| Abstract: | The activity dynamics of main protective enzymes in active oxygen elimination system of restoring and sterile rice line after damaged by white-backed planthopper (WBPH, Sogatella furcifera) and brown palnthopper (BPH, Nilaparvata lugens) were investigated. The result showed that after the infestation of WBPH, the activity of superoxide dismutase (SOD) increased and that of catalase decreased, and that of peroxidase (POD) increased in resistant rice and decreased in susceptible rice. While after the infestation of BPH, the activity of SOD increased, and those of catalase and POD decreased in resistant rice and increased in susceptible rice. Similar to the tendency that the feeding amount (indicated by honeydew amount) of BPH on rice plants was significantly higher than that of WBPH, both the increased rate of SOD in resistant rice and decreased rate of catclase in susceptible rice caused by the feeding of BPH were significantly higher than those by WBPH. |
