| 摘 要： | 采用ＳＭＶ－ａ析系为毒源接种３人不同抗性类型的大豆品种，在接种后８，２４，４８，７小时及在３，６，９，１２，１５，１８ １１次连续取样与相应ＣＫ一并测定过氧化物酶的活性后发现：未经接种的抗感品种体内ＰＯ酶活性差异较大，病品种中ＰＯ酶活性水平高于抗性品种２倍以上。

| Abstract: | Peroxidase activity were tested with leaves of resistant and susceptible soybean cultivars at 3 days interval up to 18 days and at 24 hours interval up to 72 hours. The results showed that the peroxidase activity in susceptile cultivars was higher than resistant without inoculation of SMV(CK). The resistant cultivars after inoculated with SMV-a showed an increase in peroxidase activity, the peak of peroxidase activity was at 24 hours after inocuilation with SMV. But the peroxidase activity increased greatly after 9 days and 15 days after inoculated with SMV-a. On the susceptible cultivars This results were coincided with symptoms development. The infected plants were symptomless on the resistant cultivar. |
