本研究采用菌丝融合分类法将分离和收集到的71个双核丝核菌分为7个菌丝融合群,CAG1—CAG7。这7个菌丝融合群与日本Ogoshi等人的有关研究相比较,分别等同于他们的AGD、AGBa、AGA、AGG、AGB(O)、AGK和AGF。用土壤覆盖培养法诱导了CAG5的6个分离物在室内产生有性世代,测定结果表明它们皆属于Ceratobasidium cornigerum。各融合群分离物的形态、生理和分类学问题作了分析和讨论。
In this study, 71 strains of Rhizoctonia solani isolated and collected were divided into 7 mycelial fusion groups, CAG1-CAG7 by mycelial fusion classification. These seven mycelial fusion groups were comparable to their related studies in Japan, Ogoshi et al., Respectively, with their AGD, AGBa, AGA, AGG, AGB (O), AGK and AGF. Six cultivars of CAG5 were induced to produce sexual intercourse indoors by soil overgrowth culture. The results showed that all of them belonged to Ceratobasidium cornigerum. The morphology, physiology and taxonomy of isolates of each fusion group were analyzed and discussed.
