| 摘 要： | 选用几种抗性诱导剂处理橡胶树古铜期叶片,再接种橡胶树白粉菌,以研究诱导橡胶树对白粉病产生系统性抗性的能力,并测定有效药剂BTH(苯并噻二唑)处理后,诱导间隔期及叶片抗性相关酶活性变化。结果表明,用250 mg/L BTH喷施,5 d后接种白粉病,诱导抗性效果最佳,防效达57.8%。用BTH处理并接种病原菌后,POD和PAL酶活性与对照相比显著升高,可持续到15 d,并且再次施药,酶活性再次上升。这说明BTH可以诱导橡胶树对白粉病产生系统获得抗性。在生产中,橡胶树白粉病发病前,利用BTH诱导抗病性,并结合实际情况使用常规防治,可有效减少橡胶树白粉病的发生和危害。

| Abstract: | In this experiment,the induced resistance on rubber tree to Oidium heveae was investigated by bronze-coloured 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 o... |
