摘要
采用培养性状比较和细胞核染色研究 ,确定分离自广州地区 10种作物上的 5 3个丝核菌菌株为立枯丝核菌 ,并对其进行了菌丝融合群测定 结果表明 ,5 3个菌株中有 30个菌株属菌丝融合群AG 1 ⅠA ,2个为AG 1 ⅠB ,4个为AG 1 ⅠC ,12个为AG 4 ,3个为AG 2 2 ⅢB ,尚有
isolates of Rhizoctonia spp. isolated from 10 crops in Guangzhou region were identified as R. solani based on cultural characteristics and nuclear staining. Furthermore, 53 R. solani isolates were tested on hyphal fusion with international standard isolates of anastomosis groups and intraspecific groups of R. solani . The results showed that 30 isolates were assigned to AG 1 ⅠA, 2 isolates to AG 1 ⅠB, 4 isolates to AG 1 ⅠC, 12 isolates to AG 4, 3 isolates to AG 2 2 ⅢB, and 2 isolates could not be assigned to any anastomosis groups.
