摘　　要：对薇甘菊(Mikania micrantha)叶斑病进行分离鉴定,观察病原菌形态及进行分子生物学检测,测定病原菌生长适温及寄主范围。形态学结合分子生物学鉴定薇甘菊叶斑病病原菌为大豆茎点霉Boeremia exigua,27℃为该菌菌丝生长最适温度,初步发现该菌可侵染桑树,不侵染其他参试作物。In this paper,Mikania micrantha leaf spot pathogen was isolated and identified,and the morphology and molecular biology of the pathogen was carried out to determine the suitable growth temperature and host range of the pathogen.The pathogen of Mikania Micrantha leaf spot was identified as Boeremia Exigua.,and the optimum temperature for mycelia growth was 27°C.It was preliminarily found that the pathogen could infect mulberry trees,but not other tested crops.
