对３个感病程度不同的花生品种的研究表明，接种后各品种花生植株叶片内ＰＯＤ活性明显提高，随着症状的出现，ＰＯＤ表现出显著的活性高峰，并出现了４条新的同工酶带，而原有的１条迁移率为０．３８的谱带消失。接种初期，花生叶片内ＳＯＤ活性有所提高，但高感品种接种８ｄ后ＳＯＤ活性低于健康对照，而耐病品种接种后１２ｄ才略低于对照。各处理之间ＳＯＤ同工酶谱带数相同，发病株的迁移率为０．４１的谱带较弱。
Three peanut cultivars with different susceptibilities showed that the POD activity in peanut leaves increased significantly after inoculation, and POD showed significant activity peak with the appearance of symptoms, and four new co-workers Enzyme band, while the original one with a mobility of 0.38 disappears. In the early stage of inoculation, the SOD activity in peanut leaves increased, but the SOD activity of the susceptible cultivars was lower than that of the healthy controls 8 d after inoculation, while the resistant cultivars 12 d after inoculation were only slightly lower than the control. The bands of SOD isoenzymes were the same between treatments, and the bands with the migration rate of 0.41 were weaker.
