| 摘 要： | 对油棕发生的一种严重叶部病害进行研究,对该病病原进行了分离和鉴定,经ITS序列分析确定该病病原为半知菌亚门拟茎点霉属真菌.生物学特性研究结果表明:该茵分生孢子呈椭圆形或球形,浅褐色至深褐色；马铃薯葡萄糖琼脂培养基(PDA)最适合该茵生长,其次是胡萝卜琼脂培养基(CDA)和燕麦琼脂培养基(OMA)；在10 ～30℃范围内...

| Abstract: | A pathogen causing the leaf spot disease of Elaeis guineensis Jacq was isolated and identified by ITS sequence analysis,and its biological characteristics were studied in this paper.The results showed that the pathogen was identified as Phomopsis sp.in Deuteromycotina,its conidiophore was oval or round in shape,and light brown or deep brown in color.Potato dextrose agar medium(PDA) was the optimum medium for its mycelial growth,followed by carrot agar medium(CDA) and oat agar medium(OMA).The proper temperat... |
