摘要
对陕西关中地区猕猴桃枝干及花腐病上分离的 5个菌株 ,经致病性测定、菌体形态、培养性状、生理生化及血清学反应等系统研究表明 ,病原菌接种温度为 1 5℃左右 ,伤口入侵 ,LOPAT试验的 + - - - + ,确定陕西省关中地区猕猴桃枝干细菌性溃疡病的病原为丁香假单脆杆菌猕猴桃致病变种 ( Pseudomonassyringae pv.actinidia)。
A new canker disease of kiwifruit(Actinidia deliciosa )occurred at Changan in 1990,and broken out in 1991. Since then, it becomes the most destructive disease in the region. Five isolates of the pathogen obtained from the infected kiwifruit plants at Taiyigong, Guoduzheng and Yangling orchards were tested. According to pathogenicity and hypersensitive response, morphology, cultural and staining properties, physiological, biochemistry and serological characteristics,the isolates were identified to be bacterial canker(Pseudomonas syringae pv. actinidia).
