摘　　要：以感病材料Thatcher和抗叶锈菌近等基因系TcLr28为材料,麦苗长至一叶一心期时,用浓度为200 mg/L的BION(有效成分为苯并噻二唑,BTH)喷雾处理并在4d后接种叶锈菌,测定不同时期SOD、POD、PPO、PAL、β-1,3-葡聚糖酶、几丁质酶变化的分析表明,经BION诱导后的小麦其体内的SOD、POD、PPO、β-1,3葡聚糖酶、几丁质酶的活性均高于未诱导小麦品种。The induced resistance of wheat seedling to leaf rust was tested while spraying with BION（benzo（1,2,3） thiadiazole-7-carbothioic acid S-methyl ester,BTH）.The results indicated that the activity of SOD,POD,PPO,PAL,β-1,3-glucanase,chitinase in seedling leaves were analyzed after spraying with BION at 200 mg/L and inoculation with PRT 4 days later.The results showed that the activities of SOD,POD,PPO,β-1,3-glucanase,chitinase could be increased when it was induced by BION.The relative induction effect was even better on susceptible cultivar（Thatcher） than that on resistant cultivar（TcLr28）.
