摘　　要：笔者自鸡冠花Celosia cristatal.上发现一种细菌性叶斑病。它主要危害叶片,形成圆形枯斑,边缘淡褐色,使叶片枯萎。根据病原细菌的形态染色反应、培养性状、生理生化等方面的测试,鉴定该病原菌为Erwinia chrysanthemi pv.Chrysanthemi Burkholderet al.鸡冠花是该细菌的一个新的寄主。A bacterial leaf spot disease was found on Celosia cristata L.The spots are circular with light brown margin, and often result in wilt of foliage.The pathogen isolated from the diseased leaves was identified as Erwinia chrysanthomi pv. chrysanthomi according to its bacteriological chracteristics.Celesfa crisrata L.is a new host of it.
