Abstract:

Using different application methods,the induced resistance of tomato applied by different methods of benzothiadiazole derivatives were studied.The induced resistance was studied in tomato leaves treated with 200 μg/mL benzothiadiazole derivatives solutions，spraying and spred steam two methods were used to treat the tomato.The concentration of PAL,POD,PPO and MDA in the leaves were tested.The results showed that the activity of PAL,POD and PPO were increased in tomato leaves，and the peak of those enzymes were earlier than the control,in large measures the content of MDA were lower than the control;and the treatment groups could play longer induced resistance,applying the liquid benzothiadiazole derivatives to the steams of tomato had the best effect.
