| 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）。

| Abstract: | 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. |
