| Abstract: | Growth interference in culture was shown by 57 strains of Rhizobium belonging to different inoculation groups. The assays were conducted in vitro by spot tests on agar plates and using 1007 paired combinations, 240 cases of interference were observed.A frequency of interference of about 30% was found among strains of R. meliloti and R. meliloti, R. lupini, R. trifolii and R. leguminosarum. Only one case out of 168 showed interference between R. meliloti and R. japonicum. |
