摘要
对63株新分离的内蒙古根瘤菌与6株来自Rhizobiumleguminosarum及Sinorhizobiummililoti的参比菌株一起进行了数值分类。结果表明:所有测试菌株在67%的相似性水平上分为三个表观群,群Ⅰ包括3株Sinorhizobiummeliloti的参比菌和9株新分离的内蒙古根瘤菌;群Ⅱ包括3株RhizobiumLoguminosarum参比菌和37株新分离的内蒙古根瘤菌;群Ⅲ全部由20株新分离的内蒙古根瘤菌组成。在78%的相似性水平上,全部供试菌株分为8个亚群,大部分新分离的内蒙古根瘤菌聚在6个独立的亚群中。研究结果也说明内蒙古根瘤菌的分群与其寄主无明显的相关性。
Sixty-three rhizobial strains isolated from Inner Mongolia Autonomous Region were compared with 6 representahves of recognized Rnizobium and Sinorhizobium species by performing a numerical analysis of 130 phenotypic characterishcs. The results showed that all tested strains were clustered into 3 phena at 67% similarity level. Phenon Ⅰ includes 3 representatives of Sinorhizobium meliloti and 9 rhizobial stains from Inner Mongolia; Phenon Ⅱ was composed of 3 representatives of Rhizobium leguminosarum and 37 strains from Inner Mongolia; Phenon Ⅲ were 20 strains from Inner Mongolia. All tested strains were clusted into 8 subphenoa at the similarty of 78%. Most newly isolated rhizobal strains fell in 6 distinctive subphenoa. There is no correlation between the distribution of stains in the phena and their hosts.
