摘要
为明确猕猴桃采后病害的病原种类,本研究对猕猴桃储藏期病果进行了病原真菌的分离培养,观察了病原的培养性状和形态特征,并进行了分子生物学鉴定及其致病性测定。结果表明,引起猕猴桃储藏期病害的病原真菌有7种(类),分别是链格孢菌(Alternaria spp.)、葡萄座腔菌(Botryosphaeria dothidea)、间座壳菌(Diaporthe spp.),无性态为拟茎点霉菌(Phomopsis spp.)、拟盘多毛孢菌(Pestalotiopsis sp.)、假尾孢菌(Pseudocercospora sp.)、刺盘孢(Colletotrichum sp.)、灰葡萄孢(Botrytis cinerea),研究结果可为后期猕猴桃采后病害的防控提供科学依据。
Postharvest disease of kiwifruit is one of the most important factors that can affect product quality and shelf life.The pathogenic fungi in stored kiwifruit were isolated,cultured,and identified by morphological characteristics,molecular biology method as well as pathogenicity test to determine the pathogen.The results showed that Alternaria spp.,Botryosphaeria dothidea,Phomopsis/Diaporthe spp.,Pestalotiopsis sp.,Pseudocercospora sp.,Colletotrichum sp.,and Botrytis cinerea were the 7 kinds of fungi which can cause kiwifruit diseases during storage.This research can provide a scientific basis for the prevention and control of postharvest diseases of kiwifruit.
