摘　　要：以红地球,巨峰,玫瑰香,马奶葡萄为试材,对鲜食葡萄采后腐烂病原菌进行了分离、纯化、致病力测定和鉴定及其侵染规律的研究。研究表明,引起葡萄采后腐烂的病原菌主要有灰霉,黑曲霉,青霉,根霉,链格胞和拟茎点霉属6个属。其中黑曲霉和根霉为高温致腐菌,灰霉菌和链格胞为低温致腐菌,根霉和黑曲霉只有在有伤时才可以侵入,在不同品种上或同一品种上的不同部位主要致腐菌各不相同。The postharvest pathogens for four grape cultivars were determined through isolating, purifing, pathogenicity determination, identification and infection rule. The main pathogens of grapes postharvest decay were Botrytis cinerea,Aspergillus niger, Penicillium sp p, Rhizopus stoloniter,Alternaria sp p and Phomopsis sp. Among these pathogens,Aspergillus niger and Rhizopus stolonite cause decay during high temperature, yet Botrytis cinerea and Alternaria sp p were the major pathogens below 5℃. Rhizopus stoloniter and Aspergillus niger only infect wounded fruit, the main pathogens were various among grape cultivars or organs of the same cultivar.
