- 摘要:
- 将苯并噻二唑（BTH）配制成200 μg/mL的溶液，用喷施和涂茎2种方法处理番茄苗，测定叶片内苯丙氨酸解氨酶(PAL)、过氧化物酶(POD)、多酚氧化酶（PPO）、丙二醛（MDA）的含量，研究不同剂型苯并噻二唑衍生物对番茄抗病性的诱导效果。结果表明：BTH处理的番茄叶片PAL、POD、PPO的活性均提高，且峰值出现均早于对照，MDA含量总体低于对照；而且处理组能发挥较长时间的诱导抗性，尤其以BTH乳剂配制溶液涂茎番茄诱导效果最佳。
- 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.
