Abstract Detailed individual nodulation profiles were obtained for five strains of Rhizobium leguminosarum biovar trifolii inoculated onto roots of Trifolium repens seedlings growing on an agar medium of pH 4.5. The time of appearance and the location of every nodule were noted for a period of 10 days after inoculation. Using these nodulation frequency profiles, pairings of strains were identified and six mixed-strain inoculation (1:1 ratio) experiments were subsequently performed at pH 4.5. Results from the mixed-inoculum experiments showed that the performance of a Rhizobium strain in single culture could not be reliably used to predict the outcome of a paired-inoculation study and that some seedlings were exclusively nodulated by rhizobia that performed poorly at low pH in single-culture inoculations.
