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).
