摘要
调查观察了４８属１２２种豆科树种的结瘤情况，其中８２种结瘤。采用ＶｉｎｃｅｎｔＪＭ分离方法［１］，从根瘤中分离获得了１２３个根瘤菌株的纯培养，各菌株的菌落特性和生长速度差异明显．经回接和交叉接种试验进一步确定它们为豆科树种根瘤菌。
genera 122 speciss of tree legumes were examined for nodulation in field and seedling nursery. Among them, 82 species were found to be nodulated. 123 strains of root nodule bacteria from nodules of the trees were isolated following the method suggested by Vincent (1970). Isolates of rhizobia were purified and maintained on YEMA slants. Strains of rhizobia obviously differ from one another in characteristics of colonies and growth rate.
