摘　　要：通过病原菌的形态特征、致病性测定和rDNA-ITS序列分析,对引起猕猴桃枝枯病的病原菌进行了分离鉴定。结果表明:猕猴桃枝枯病的主要病原菌为拟茎点霉菌(Phomopsis sp.)、隔孢丛壳菌(Glomerella septospora)和葡萄座腔菌(Botryosphaeria dothidea),3种病菌所占比率分别为39%、38%和23%,且无论是孢子悬浮液接种还是菌丝体接种均只能通过伤口侵染而引起枝条发病。The pathogen caused shoot blight of kiwifruit were isolated and characterized with the pathogeificity test, morphology and rDNA-ITS sequence assay. The results showed that three kinds of fungi were responsible for shoot blight of kiwifruit in Fengxin County. They were Phomopsis sp. ,Glomerella septospora and Botryosphaeria dothidea, which accounted 39% ,38% and 23% respectively. Three kinds of fungi penetrated shoot of kiwifruit through wounds including PDA plug inoculation and conidial suspension inoculation.
