【摘要】[目的]为拮抗菌的商业化贮藏应用提供依据.[方法]通过室内培养筛选出2株具有拮抗效果的酵母菌,通过活体和离体试验,研究拮抗酵母菌对青霉引起的苹果采后痛害的防治效果.[结果]活体条件下,含量为2×108CFU/ml的2株酵母菌对青霉菌具有较明显的抑制效果,其中菌株1的防效为89%,菌株2的防效为92%;离体条件下,含量为106CFU/ml的2株酵母菌可完全抑制青霉菌生长;用酵母菌菌悬液浸果后,贮藏20 d时苹果未出现腐烂现象,20 d后酵母菌菌株2在苹果上的数量为初始值的15.0倍,菌株1在苹果上的数量为初始值的10.2倍.[结论]2株酵母菌均可在苹果伤口上迅速繁殖,可有效防治苹果青霉痛.%[ Objective] The aim was to supply basis for commercialized storage and application of antagonistic fungus. [ Method ] Two yeast strains with antagonistic effect were screened out through indoor culture, and the control effect of yeast antagonist on post-harvest disease of appie induced by blue mold was studied through in vivo and in vitro experiments. [ Result ] In vivo, 2 × l08 CFU/ml of the 2 yeast strains had relatively obvious inhibition effect on blue mold and the control effects of the strain I and 2 were 89％ and 92％ resp. In vitro, 106 CFU/ml of the 2 yeast strains could inhibit the growth of blue mold completely. After the fruit had ever been soaked in yeast suspension, the apples did not
