摘　　要：以山东省寿光市保护地栽培蔬菜上分离的30个灰霉病菌菌株为试材,采用菌落培养性状观察和菌饼活体接种法,研究灰霉病菌的菌系划分及对黄瓜叶片的致病力差异。结果表明:供试菌株划分为菌核型、菌丝型和孢子型3个菌系,不同菌株对黄瓜叶片的致病力分化显著,致病力强弱与寄主植物无显著相关性;强致病力菌株以菌核型为主,菌丝型和孢子型菌株致病力相对较弱。Taking thirty isolates of Botrytis cinerea as experimental materials which were obtained from the protected vegetables in Shouguang of Shandong Province. Based on the colony culture characters and applying mycelia block inoculation, the strain distribution and pathogenicity differentiation to cucumber leaves were detected. The results showed that all tested isolates were classified in three strains： sclerotium, sporutation and mycelial. There was significant differentiation in pathogenicity to cucumber leaves between all tested isolates and the pathogenicity difference was not significant related to the host. The isolates with strong pathogenicity were mainly sclerotium strain while the pathogenicity of sporutation and mycelia strains were relatively weak.
