摘要
福建漳州是景天科Crassulaceae多肉植物翡翠景天Sedum morganianum主产地。近年来,该植物黑腐病发病严重,为鉴定其病原菌,从福建漳州3个翡翠景天种植基地采集典型病株并分离病原菌,基于形态学观察及rDNA-ITS、actin、EF-1α基因序列分析和致病性测定,界定该病原菌为山扁豆生棒孢Corynespora cassiicola。该菌引起多肉植物翡翠景天黑腐病为世界首次报道。
Zhangzhou of Fujian Province is productive area of ornamental succulent plant Sedum morganianum of Crassulaceae,where black rot disease seriously occurred in recent years.Morphological observation,and rDNA-ITS,actin,EF-1αgene sequence analysis have proved that the pathogen is Corynespora cassiicola.This is the first report of black rot of S.morganianum caused by Corynespora cassiicola.
