摘　　要：罗伦隐球酵母菌 [Cryptococcuslaurentii (Kuffer .)Skinner]是从苹果果实表面分离筛选获得的一种广谱抗性的拮抗菌。通过对该拮抗菌对葡萄 (VitisL .)采后由于机械伤引起的自然发病的抑制效果研究表明 ,C .lau rentii能有效抑制葡萄采后伤口引起的自然发病率 ,其拮抗效果与拮抗菌的使用浓度成正比。外加钙离子对拮抗菌的抑病效果没有明显作用 ,而外加一定浓度的NYDB营养液能提高该拮抗菌在伤口处的菌群数量 ,大幅度增加其抑病效果。同时 ,在NYDB营养成分中 。Cryptococcus laurentii (Kuffer.) Skinner, isolated from apple fruits, was an effective antagonist for control of postharvest diseases in many fruits. The biocontrol efficacy of the antagonist to disease caused by wound in grapes fruits(Vitis L.)was investigated in this study. It was found that C. Laurentii significantly decreased disease incidence. Addition of CaCl 2 did not enhance biocontrol efficacy of C. Laurentii on diseases, while the antagonist combining with NYDB broth showed a better effect on controlling diseases. Yeast extract powder was the most effective among the different components of NYDB to enhance efficacy of the antagonist.
