摘　　要：以茄子的不同抗、感黄萎病品种为材料,研究苗期感染黄萎病菌后,根部组织内防御酶系的活性变化。结果表明:经哈茨木霉T6处理的不同抗、感茄子品种幼苗根系的PAL、POD、PPO和SOD存在明显变化,4种酶活性与对照相比均有一定程度的升高,但抗病品种的酶活性增加幅度高于感病品种。证明茄子根系经诱导后可产生植保素等相关物质参与抵抗黄萎病。Defense enzymes in root of eggplant seedling were examined treating with T6.The results showed that the activities of defense enzymes in eggplant root such as PAL,POD,PPO,SOD were changed by T6.The enzyme activities of resistant varieties ware higher than susceptible ones.It indicated that the production of phytoalexin might be involved to resistant eggplant verticillum wilt.
