摘　　要：采后腐烂给南瓜生产带来巨大的经济损失。为明确山东省青岛胶州南瓜果实腐烂病的病原,采用分子生物学和形态学鉴定方法,依据柯赫氏法则,对病原菌进行分离和鉴定。结果表明,从发病南瓜果实上共分离出2种菌株;经鉴定,引起南瓜果实腐烂的病原菌分别为腐皮镰刀菌(Fusanrum solani)和匍枝根霉菌(Rhizopus stolonifer)。这是我国腐皮镰刀菌和匍枝根霉菌侵染南瓜果实的首次报道。Post-harvest fruit rot has brought huge economic loss to pumpkin production.In order to exploit the pathogen of pumpkin fruit rot in Jiaozhou,Qingdao of Shandong Province,this study isolated and identified the pathogen by molecular biology and morphology method and according to Koch’s Rule.Results indicated that 2 kinds of bacterial strain were isolated from the infected pumpkin fruit.They were the pathogens causing pumpkin fruit rot.They were identified as Fusarium solani and Rhizopus stolonifer,respectively.This is the first report in China that Fusarium solani and Rhizopus stolonifer could infect pumpkin fruit.
