摘　　要：为了探明适合中国葡萄灰霉病菌致病力检测的方法以及合适的待测葡萄品种,采用菌丝块接种法和改良的保湿培养法,分别测定3个不同致病力类型的灰葡萄孢霉(Botrytis cinerea)菌株SDXL7-1、SDLK1-1、LNXCetz6-1对红提、青提、巨峰、紫奶、玫瑰香5个葡萄品种的致病力,并进行差异分析。结果表明,供试菌株均可引起5种葡萄发病,但致病力不同的菌株所致的平均病斑面积有明显差异,同一菌株在不同葡萄品种上的平均病斑面积也有明显差异。其中,巨峰和青提对灰葡萄孢霉具有较强抗性,红提和玫瑰香对3个灰葡萄孢霉菌株普遍易感,紫奶对菌株LNXCetz6-1具有较强抗性,但对另外两个菌株易感。试验结果为系统和全面地研究中国灰葡萄孢霉菌株的致病力分化提供重要依据。To study the method and the grape that suitable to detecting the pathogenicity of Botrytis cinerea,using the hypha blocks inoculation and improved moisture culture methods,the pathogenicity of three different pathogenic types of B.cinerea SDXL7-1,SDLK1-1,LNXCetz6-1to five grapes,such as Red Globe Grape,Green Globe Grape,Kyoho Grape,Purple Milk Grape,and Muscat Hamburg Grape,were determined.The results showed that all of the tested isolates caused grey mould on five grapes,but there was significant difference in the average area of the lesions caused by different isolates or on the different grapes.Kyoho and Green Globe had a strong resistance to these strains,while Red Globe and Muscat Hamburg were generally susceptible to three strains,and Purple Milk was stronly resistant to strain LNXCetz6-1,but susceptible to other two strains.The analysis of pathogenicity diversity to different grape varieties provided an important basis for the detection and pathogenicity differentiation of B.cinereain China.
