摘要:: 通过对玉竹叶斑病病原菌一系列分离、纯化、接种试验进行病原鉴定，并在实验室条件下，对玉竹叶斑病菌进行了生物学特性研究。结果表明：结合查阅中国科学院中国孢子植物志编辑委员会编辑的《中国真菌志》第16卷链格孢属，初步确认病原为日光兰链格孢（Alternaria asphodeli）；适宜菌落生长的碳源为木糖；适宜菌落生长的氮源为硝酸钾；适宜菌落生长温度为25℃；适宜菌落生长的pH为6~7；全光照条件下适宜菌落生长。

Abstract:: The pathogens of leaf spot in odoratum was recognized as Alternaria asphodeli by separation，purification，vaccination experiments pathogens was determinated. Under laboratory conditions，the biological characteristics of leaf spot in odoratum was researched.The results showed that combined the inspection of the volume XVI ‘China Fungal Annals’ edited by Editorial Board of China Spore Flora in Chinese Academy of Sciences.Xylose was the suitable carbon source for the colony growth;KNO₃ was the suitable Nitrogen source for the colony growth;25℃was the suitable temperature for the colony growth;6~7 was the suitable pH value for the colony growth;and all light conditions was suitable for colony growth.
