Abstract:
:The competitiveness of fourRhizobium sp. strains infectingAcacia senegal and originating in the Sudan was assessed in a growth chamber experiment using Sudanese soil, WhenAcacia senegal was inoculated with pure cultures of the strains, there were statistically significant differences among the strains with respect to the numbers of nodules formed, the amount of dry matter produced and acetylene reduction activity. However, the best strain when applied as a pure culture, was only the second best as a competitor. Two strains with inferior symbiotic capabilities were also bad competitors but nevertheless reduced the yields of the plants when they were applied as inocula mixed with the better strains. The bacterial markers used to assess nodule occupancy were resistance to streptomycin or spectinomycin. Two of the strains formed the dark-brown pigment melanin. Melanin production was a stable characeristic, well suited to serve as an intrinsic identification marker when assessing the competitiveness of melanin-producing versus non-producing strains in controlled conditions.
