| 摘 要： | 于2002-2005年连续3年观察了杭州龟甲冬青枝枯病的症状，该病害先在嫩枝枝条发病，病斑初为水渍状斑点，后扩大成暗褐色的不规则形病斑。从发病部位分离培养出病原菌，根据其分生孢子的形态、大小和核糖体DNA内转录间隔区的序列，鉴定为褐纹拟茎点霉［Phomopsis vexans (Sacc.et Syd.) Harter］。本文对该病害症状和病原形态特征进行了描述。 |

| Abstract: | Blight symptoms on twigs and branches were observed on Ilex crenata ‘Convexa’ in summer during 2002-2005. The twigs and branches showed small water soaked discoloration spots which rapidly turned into irregular lesions, with a brown outer edge and a dark brown sunken central area. The pathogen was isolated from the diseased tissues. It was identified as Phomopsis vexans (Sacc. &; Syd.) Harter based on morphology and ITS sequences. The disease symptoms and the morphological characters of the pathogenic fungus were described. |
