| 摘 要： | 目的]研究阿月浑子褐斑病的发病规律及其病原菌的生物学特性。方法]田间实地调查阿月浑子褐斑病的发病规律;从阿月浑子发病组织中分离纯化出一种真菌,室内观察其培养性状和形态特征,根据其形态鉴定其分类地位;研究了不同温度对病原菌菌丝生长的影响以及不同温、湿度对病原菌孢子萌发的影响。结果]阿月浑子褐斑病是一种真菌性病害,主要侵染阿月浑子叶片和果实,造成叶斑和枯梢,在我国的阿月浑子引种地发病情况严重。该病原真菌经鉴定为链格孢（Alternaria alternaria）,其菌丝生长的最适温度为20～25℃;孢子萌发最适温度为25～30℃,最适相对湿度在95%以上。结论]春夏之交和夏秋之交是病害发生的2个高峰期,夏季连续阴雨是阿月浑子叶片褐斑病侵染和爆发的决定性条件。
