Survival of Rhizobium phaseoli in Coal-Based Legume Inoculants Applied to Seeds.
نویسندگان
چکیده
Eight coals used as carriers in legume inoculants promoted the survival of Rhizobium phaseoli on pinto bean seeds. Although peat was more protective, most coal-based inoculants provided >10 viable rhizobia per seed after 4 weeks.

Survival of Rhizobium phaseoli in Coal-Based Legume Inoculants.
The long-term survival of Rhizobium phaseoli strains 127K17, 127K26, and 127K35 in legume inoculants prepared with eight different coals (one strain and one coal per inoculant) was studied. The coals used were Pennsylvania anthracite, bituminous coals from Illinois, Pennsylvania, and Utah, lignite from North Dakota and Texas, and subbituminous coals from New Mexico and Wyoming; they ranged in p...
متن کاملDilution of liquid Rhizobium cultures to increase production capacity of inoculant plants.
Experiments were undertaken to test whether peat-based legume seed inoculants, which are prepared with liquid cultures that have been deliberately diluted, can attain and sustain acceptable numbers of viable rhizobia. Liquid cultures of Rhizobium japonicum and Rhizobium phaseoli were diluted to give 10, 10, or 10 cells per ml, using either deionized water, quarter-strength yeast-mannitol broth,...
متن کاملSurvival of several Rhizobium/Bradyrhizobium strains on different inoculant formulations and inoculated seeds.
The effect of a variety factors on the survival of several rhizobia strains on inoculants and inoculated seeds has been evaluated. Since the rhizobia strains showed different cell-density-evolution patterns on peat-based inoculants and on inoculated seeds, several inoculant formulations with highly effective Rhizobium/Bradyrhizobium strains (for Lupinus, Hedysarum, Phaseolus and Glycine max.) w...
متن کاملProduction of bacterial inoculants by direct fermentation on nutrient-supplemented vermiculite.
When supplemented with a nutrient source and moisture, sterile finely ground vermiculite can be used to directly ferment bacterial cultures to prepare bacterial inoculants. All tested bacterial species, including Rhizobium japonicum, R. phaseoli, R. meliloti, R. leguminosarum, Bacillus megaterium, and several Pseudomonas strains, grew at least 10,000-fold in 1 week at room temperature. The fina...
متن کاملResidues of the Cork Industry as Carriers for the Production of Legume Inoculants
Growth and survival of two rhizobial strains, Rhizobium leguminosarum bv. trifolii, and Mesorhizobium ciceri, were used to evaluate residues from the cork industry as potential carriers for production of rhizobial inoculants. A peat-based carrier was used as a control. 41 days after inoculation, the number of viable bacteria was high, about 109 bacteria g-1 for all carriers. Rhizobial survival ...
