摘要
2008—2009年,从广东省湛江等地采集疑似疫病的马拉巴栗病株,经病原菌分离及柯赫氏法则验证,证明其病原菌是疫霉菌。通过致病性、寄主范围测定,菌体形态,培养特性及rDNA-ITS序列分析等,将该病原菌初步鉴定为棕榈疫霉(Phytophthora palmivora)。
The diseased plants of Pachira macrocarpa showing symptoms of phytophthora blight were collected from Zhanjiang,Guangdong Province from 2008 to 2009.This study proved that the pathogen was a kind of fungus by test of Koch’s postulates.The pathogenic fungus was identified as Phytophthora palmivora based on pathogenicity and morphology,host range and sequence analysis of rDNA-ITS.
