| 摘 要： | 以甜瓜品种银帝和卡拉克赛为试材，在伸蔓期、初花期和幼果期进行苯并噻二唑（BTH）处理，研究BTH对甜瓜霜霉病、白粉病和炭疽病的防控效果。结果表明：与对照相比，BTH处理后显著降低了银帝和卡拉克赛的病株率和病情指数，各处理的防病效果品种间存在差异；对霜霉病，幼果期BTH处理效果较好，采前7 d时，伸蔓期+幼果期BTH处理诱导防病效果较好，两品种分别达到40.00 %和49.62 %；对白粉病，各处理对银帝的防病效果在采前7 d时高达75 %，银帝病株率和病情指数都低于卡拉克赛，且发病较卡拉克赛晚；幼果期BTH处理后显著降低了银帝和卡拉克赛发病初期炭疽病的病株率和病情指数，采前7 d时对银帝的诱导防病效果是幼果期BTH处理较好，为72.79 %，对卡拉克赛则以伸蔓期+幼果期BTH处理的诱导防病效果较好。

| Abstract: | This test took disease-resistant melon(Cucumis melon L.)cultivar-'Yindi'and susceptible variety-'Kalakesai'as material,and studied the inducing effects of BTH on resistance to downy mildew,white powder,anthrax at three stages of melon plants treated with BTH.The results showed that after treating the melon at periods of vine extend,early florescence,young fruit with BTH,the'Yindi'and'Kalakesai'infected plant rate and disease index reduced conspicuously,compared with the contrast.But there were differences i... |
