BTH诱导橡胶树对白粉病的抗性效果和相关酶活性测定
Effects of Rubber Tree Resistance Induced by BTH to Oidium heveae and Assay of Resistance-related Enzymes
摘要
Abstract
In this experiment, the induced resistance on rubber tree to Oidiurn heveae was investigated by bronzecoloured leaves of rubber budding seedlings treated with several resistance inducers and then inoculated the leaves with Oidium heveae. The period of induced interval and resistance-related enzyme activity of leaves after BTH treatments were determined. The results showed that a better concentration of BTH induced resistance on rubber tree to Oidium heveae was 250 mg/L, up to 57.8％ control and the best period of induced interval was 5 days after BTH treatment. The activities of phenylalanine ammonia lyase (PAL) and peroxidase (POD) increased significantly compared with the control after rubber tree leaves treated with BTH and then inoculated with Oidium heveae. This indicated that BTH could induce the systemic resistance on rubber tree to Oidium heveae. BTH induced disease resistance and combined with general control methods should be reduced effectively Oidium heveae infestation and decreased economic losses before Oidium heveae occurrence in rubber production.关键词
