Creator:: Leung, Kam-tin
Abstract:: Nodulation success by two indigenous Rhizobium trifolii serogroups, 6 and 36, on subterranean clover (Trifolium subterraneum L.) was affected by the addition of phosphate to Abiqua soil (Ultic Haploxeroll). To understand the impact of phosphorus nutrition on the survival and nodulation characteristics of the two serogroups, studies were carried out...

Creator:: Yap, Kathryn H. M.
Abstract:: Although much has been learned about the comparative nodulating behavior of simple mixtures of rhizobial strains under non-soil situations, it is unclear how these findings relate to the factors influencing nodulation success by the complex mixtures of strains found within soil-borne rhizobial populations. Information on the structure and physiological behavior...

Creator:: Cheng, Hsin-hua
Abstract:: Although the biology of Bradyrhizobium has been studied for almost one hundred years, virtually nothing is known about the ecology and genetic variation in natural soil populations of this genus. The majority of information has been obtained from studies of one species, Bradyrhizobium japonicum, and the diversity within soil populations...

Creator:: Wanjagi, Francis Ndung'u
Abstract:: In a series of greenhouse experiments, isolates representing serotypically distinct subpopulations of Rhizobium leguminosarum bv. trifolii recovered from root nodules of field-grown subclover Trifolium subterraneum cv. "Nangeela"), were evaluated for their symbiotic effectiveness potential, their effect on regrowth potential of subclover, and for their competitive abilities to form nodules. Isolates...
