摘　　要：猕猴桃采后腐烂在我国发生普遍。本试验对来自陕西、四川、湖北、山东和江西五省的773个猕猴桃病果进行组织分离,获得739个真菌分离株。经ITS序列比对及代表菌株的科赫式法则验证,确定其中722个菌株为猕猴桃采后腐烂病病原,属于以下11个属:Botryosphaeria、Diaporthe、Neofusicoccum、Alternaria、Botrytis、Fusarium、Cladosporium、Sclerotinia、Rhizopus、Lasiodiplodia和Pestalotiopsis。以Botryosphaeria dothidea和Diaporthe spp.为优势种群,分别占总病原数的45.29%和45.15%。病原多样性分析显示,相同产区猕猴桃采后腐烂病病原种类相似。Postharvest diseases are very severe and harm the development of kiwifruit production.773 kiwifruits were collected from Shaanxi,Sichuan,Hubei,Shandong and Jiangxi provinces,and 739 fungal isolates were obtained.Combined the ITS sequences and the results of the pathogenicity test,722 isolates were classified into 11 genera,namely Botryosphaeria,Diaporthe,Neofusicoccum,Alternaria,Botrytis,Fusarium,Cladosporium,Sclerotinia,Rhizopus,Lasiodiplodia,and Pestalotiopsis.Among them,Botryosphaeria dothidea and Diaporthe spp.are the dominant groups,accounting for 45.29%and 45.01%,respectively.Pathogen diversity analysis showed that pathogens were similar among the same areas.
