摘要
药效试验表明,玫瑰黄链霉菌Men-myco-93-63发酵液对黄瓜白粉病有良好的防效,其中发酵液保护作用的防效为88.63%,治疗作用的防效为82.26%,表明该发酵液对黄瓜白粉病的防治既有保护作用又有治疗作用。通过对喷施发酵液后黄瓜叶片内的抗病相关酶的活性的测定发现,喷施Men-myco-93-63发酵液后黄瓜叶片内POD,CAT,PAL,PPO等酶的活性在一定时间内有明显上升的趋势。
The significant controlling effect of the fermentation broth of Stremptomyces roseoflavus Men-myco-93-63 on cucumber powdery mildew were proofed through the efficacy test. There are two kinds of controlling effect of the fermentation. One is the protecting effect, which was 88.63 % in our test. Another is treating effect, which was 82.26%. Several resistance-related enzymatic activities of the leaves of cucumber were detected, such as peroxidase(POD), catalase (CAT), phenylalanine ammonia-lyase(PAL), and polyphenol oxidase (PPO). All of the activities of these enzymes in the treated cucumber seedlings were higher than those in the untreated at the certain periods.
