摘　　要：甜樱桃细菌性果斑病为近年来发生在辽宁省大连地区樱桃上的一种新病害。经病原菌分离及柯赫法则验证,证明引起该病的病原菌为一种细菌,根据分离株培养特性、生理生化反应、致病性及16S rDNA序列分析,将该病原细菌初步鉴定为成团泛菌Pantoea agglomerans。成团泛菌侵染引起的樱桃果斑病在国内外尚属首次报道。Fruit spot disease is a new disease of cherry occurring in Liaoning province in recent years. This research proved that the pathogen causing this disease is a bacterium by isolating the pathogen and tested with Koch＇s postulates. The pathogen was identified as Pantoea agglomerans based on morphological, physiological and biochemical characteristics, pathogenicity and sequence analysis of 16S rDNA. This is the first report that P. agglornerans caused the fruit spot disease on cherry in China even in the world.
