Influences of soil acidity and variety of plant on the populations of Rhizobium trifolii found in nodules of Trifolium subterraneum L.

Creator:

Dughri, Muktar H.

Abstract:

Complementary methods of strain identification were sought to delineate the composition of the population of Rhizobium trifolii found in nodules of Trifolium subterraneum L. when exposed to an Abiqua silty clay loam (Cumulic Ultic Haploxeroll) containing a resident population of R. trifolii. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDSPAGE) was...

Influence of soil acidity upon nodulation and growth characteristics of Trifolium subterraneum L.

Creator:

Almendras, Angela S.

Abstract:

Previous research had identified four serogroups of Rhizobium trifolii indigenous to Abiqua soil (fine, mixed, mesic, Cumulic Ultic Haploxerolls). Nodulation of subterranean clover (Trifolium, subterraneum L.) by two of the serogroups, 6 and 36, was influenced by the application of CaC0₃ to the soil. The studies described in this thesis...

Influences of phosphate on the growth and nodulation characteristics of Rhizobium trifolii

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...

Novel characteristics (Intra and Ex planta) of indigenous serogroups of rhizobium meliloti

Creator:

Busse, Matt D.

Abstract:

This thesis presents novel findings regarding symbiotic, physiological, and antigenic characteristics of representatives from an indigenous soil-borne population of Rhizobium meliloti. Nodules were sampled from 'Vernal', 'Anchor', and 'Saranac' alfalfa, and the isolates analyzed serologically. Rhizobium meliloti serogroup 31 was identified as a dominant nodule occupant, with a greater and...
