| 摘 要： | 从13种植物上分离得到58个丝核菌(Rhizoctonia spp.)菌株,在确定其种类和融合群的情况下,将所有供试菌株分别接种于水稻(Oryza sativa L)、甜玉米(Zea mays var.saccharata)、黄瓜(Cucumis sativus)及甘蓝(Brassica capitata)上,测定其致病性.结果表明:从玉米(Zea mays)和甜玉米上分离得到的菌株(大部分归属于AG-1)的致病力最强;其次为其它植物上分离的菌株(归属于AG-4),其致病力属于中等;从其它植物上分离得到的、归属于其它融合群及非立枯丝核菌的菌株的致病力最弱.

| Abstract: | Fifty-eight isolates of Rhizoctonia spp.were isolated from thirteen plants in Guangdong Province.After determining their classification of Rhizoctonia spp.and anastomosis groups(AGs)of Rhizoctonia solani,these isolates were all tested on rice,sweet corn,cucumber and cabbage to determine their cross pathogenicity.The results showed that the isolates from corn and sweet corn,which were assigned to AG-1,had strong pathogenicity on the four tested plants;while isolates from other plants,which were assigned to A... |
