摘要: 【目的】明确设施番茄灰霉病的病原菌种类。【方法】对采自内蒙古呼和浩特市和乌兰察布市3个设施番茄种植地块的疑似灰霉病病样进行分离,利用形态学、分子生物学方法对分离菌株进行鉴定,在离体茎秆和果实上依照柯赫氏法则进行病原菌致病性回接测定和再分离。【结果】从病茎和病果上共分离到7株病原菌,ITS rDNA序列与灰葡萄孢菌(Botrytis cinerea)的同源性为99.60%~100%(GenBank的序列登录号为KP151610、KX426964、ON566787),说明7株菌均属于灰葡萄孢菌。挑选其中2株菌G4和JW1接种到健康的设施番茄茎秆和果实上,灰霉病的发病率为100%。【结论】引起设施番茄灰霉病的病原菌为灰葡萄孢菌。

Abstract: 【Objective】To identify the pathogen species causing gray mold on facility tomato.【Methods】Suspected gray mold disease samples were isolated from tomato cultivation plots in three facilities in Hohhot City and Ulanqab City,Inner Mongolia. Morphological and molecular biology methods were used to identify the isolated strains. The pathogenicity of the pathogens was determined and re-isolated on detached stems and fruits according to Koch′s rule.【Results】Seven strains of pathogen were isolated from diseased stems and fruits. The ITS rDNA sequences were 99.60%-100% homologous with Botrytis cinerea(GenBank registration number KP151610,KX426964,and ON566787),indicating that all the seven strains were Botrytis cinerea. Two strains,G4 and JW1,were selected and inoculated on the stems and fruits of healthy facility tomato. The incidence rate of gray mold was 100%.【Conclusion】The gray mold pathogen in facility tomato was Botrytis cinerea.

Key words: Tomato, Gray mold, Botrytis cinerea
