摘　　要：首次报道了万年青（Ｒｏｈｄｅａｊａｐｏｎｉｃａ（Ｔｈｕｎｂ．）Ｒｏｔｈ）细菌性叶斑病和叶枯病在我国的发生。对分离到的４个菌株经致病性测定，电镜形态观察，培养性状和生理生化性状的测定，初步确定引起万年青细菌性叶斑病的病原为Ｅｒｗｉｎｉａｈｅｒｂｉｃｏｌａ（Ｌｏｈｎｉｓ）Ｄｙｅ，叶枯病的病原为Ｐｓｅｕｄｏｍｏｎａｓｐｓｅｕｄｏａｌｃａｌｉｇｅｎｅｓｓｕｂｓｐ．It is the first report of Everlasting green bacterial diseases in China. Four isolates of bacteria obtained from diseased Everlasting green plants are tested in Changchun. According to their pathogenic, morphological, cultural, physiological as well as biochemical characteristics, the pathogens are identificated Erwinia herbicila(Lohnis) Dye. for bacterial leaf spot and Pseudomonas pseudoalcaligenes subsp. rohdea for leaf blight disease.
