| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
