苜蓿假盘菌;侵染能力;专化性
摘  要:
对豆科牧草的5个属14个种在实验室条件下进行苜蓿假盘菌接种,并观察苜蓿假盘菌的寄主范围,试验结果表明:苜蓿假盘菌可以危害苜蓿属的紫花苜蓿、杂花苜蓿、镰荚苜蓿,草木樨属的白花草木樨、黄花草木樨,三叶草属的库拉三叶草。说明苜蓿假盘菌具有寄主专化性。经室内鉴定,苜蓿假盘菌可以在苜蓿属和黄花草木樨上产生成熟的子实体及子囊孢子,而在白花草木樨和库拉三叶草上不能形成子实体。

摘  要:
The virulence and infectivity of Pseudopeziza medicaginis to some lequminosae was observed by artificially inoculating the pathogens to 14 species of 5 categories.The results showed that the hosts of P.medicaginis were Medicago sativa,M.varia,M.falcate,Melilotus medic,M.officinalis and Trifolium ambiguum.P.medicaginis could sporulate on Medicago L.and Melilotus officinalis.It was shown that P.medicaginis was physiologically specialized and spent its sexual stage on Medicago L.and Melilotus Mill..
