| 摘 要： | 为明确广西油茶炭疽病病原菌种类及其生物学特性,通过形态学方法对分离获得的病原菌进行初步鉴定,以核糖体内转录间隔区、微管蛋白基因、几丁质合成酶基因、肌动蛋白基因、3-磷酸甘油醛脱氢酶基因进行多基因系统分析鉴定;并用十字交叉法、菌丝干重法和血球计数法对其生物学特性进行研究。结果表明,经形态学和多基因联合系统结合分析鉴定,广西油茶炭疽病病原菌为胶孢炭疽菌Colletotrichum gloeosporioides Penz.。该病原菌生长温度范围为10~35℃,最适生长温度为28℃;产孢温度范围为15~32℃,最适产孢温度为32℃;生长p H范围为3~11,最适生长p H为4;可促进菌丝生长并适合产孢的碳源为菊糖,阿拉伯树胶粉抑制菌丝生长但可促进产孢;对菌丝生长及产孢均有促进作用的氮源为酵母粉和牛肉膏,而硫酸铵和硝酸铵则表现抑制作用。
