摘要
通过室内和田间人工接种苜蓿锈病病原物，观察苜蓿锈病的寄主范围。研究表明，苜蓿锈病的寄主除苜蓿属的植物外，扁蓿豆属的扁蓿豆、三叶草属的白三叶草、野火球等均是该病原锈菌的夏孢子的寄主，大戟属的乳浆大戟是苜蓿锈菌的转主寄主。扁蓿豆、野火球是国内外未见报道的新寄主，乳浆大戟是国内尚未见报道的转主寄主。
The host category of Uromyces striatus Schrot was observed by means of artificial inoculating pathogens of Uromyces striatus Schrot. The results showed: besides Medicago sativa, the hosts of Uromyces striatus uredinispores Schrot were, Medicago ruthenicus, Trifolium repens and Trifolium lupinaster; the hosts of Uromyces striatus Schrot was Euphorbia esula L. Medicago ruthenicus and Trifolium lupinaster were new hosts, Euphorbia esula was new alterhate host.
