茶云纹叶枯病病原鉴定

Identification of Pathogenic Fungus Causing Tea Brown Blight

为了对防治茶云纹叶枯提供理论依据,结合形态学和分子生物学的方法,对贵州省黔南州都匀茶场的茶云纹叶枯病的病原菌进行了鉴定。结果表明:都匀地区茶云纹叶枯病的病原菌为围小丛壳菌山茶专化型(Glomerella cingulataf.sp.camelliae),其无性态为炭疽菌属(Collectotrichum)。

The pathogenic fungi of tea brown blight from Duyun Tea Farm,in Guizhou were identified by morphology and molecular biology methods to provide the theoretical basis for control of tea brown blight.The results showed that the pathogenic fungus of tea brown blight from Duyun Tea Farm is Glomerellacingulataf.sp.camelliae and its asexual morphology belongs to Collectotrichum.
