| 摘 要： | 以对ＳＭＶ－ａ株系抗性不同的３个大豆品种为材料，分析了感染ＳＭＶ后苯丙氨酸解氨酶，过氧化物酶，超氧化物歧化酶和过氧化氢酶活性的动态变化。结果表明，抗病品种科丰１号接种ＳＭＶ的早期，ＰＡＬ和ＰＯＤ活性显著升高，ＳＯＤ和ＣＡＴ活性明显下降，相反感病品种１１３８－２和徐豆１号的ＳＯＤ和ＣＡＴ活性明显上升，ＰＯＤ活性的增加幅度则小于抗病品种，而１１３８－２的ＰＡＬ活性则低于相应对照。

| Abstract: | Dynamic changes in activities of phenylalanine ammonia lyase (PAL), peroxidase (POD), superoxide dismutase (SOD) and catalase (CAT) were tested with leaves of resistant and susceptible soybean cultivars during infection by SMV-a. The results suggested that at the early stage of infection PAL and POD activities of resistant soybean cultivar (Kefeng-1) increased rapidly, SOD and CAT activities decreased dramatically. On the other hand, the changes of POD were relatively smaller in leaves of susceptible soybean cultivars (1138-2 and Xudou-1), SOD and CAT activities showed an increase and PAL activities of 1138-2 declined. |
