The growth responses of Phaseolus vulgaris L., cv. "Red Kidney" plants to simazine at 5 x 10~M and 5 x 10^M, kinetin at 9 x 10~M and 9 x 10~M, and the presence or absence of Rhizobium phaseoli ATCC14482, in factorial combination, were measured. The plants were analyzed with respect to the lengths of the primary-through-quaternary leaves, stem height, fresh and dry weights, number of flowers, an...

A symbiotic strain was isolated from the root nodules of the legume pulse Phaseolus mungo L and designated as PM 25. The strain was identified as Rhizobium sp. on the basis of the physiobiochemical characteristics and 16S rDNA sequence based homology. The Minimum Inhibitory Concentration of the analogue 5-fluro-tryptophan was 3.0 mM. The analogue (5FT) resistant mutants were screened from wild ...

The influence of rhizosphere/rhizoplane culture conditions on the ability of various rhizobia to bind soybean seed lectin (SBL) was examined. Eleven strains of the soybean symbiont, Rhizobium japonicum, and six strains of various heterologous Rhizobium species were cultured in root exudate of soybean (Glycine max [L.] Merr.) and in association with roots of soybean seedlings which were growing ...

Background: Cowpea (Vigna unguiculata L.) an important and commonly grown kharif pulse crop in India for vegetable, grain, forage green manuring. Considering the adverse effects of chemical fertilizers, bio-inoculants should be encouraged as natural nutrient source. Methods: Three indigenous viz., Rhizobium sp., Bacillus megaterium Glomus mosseae were evaluated a field experiment which was cond...

An experiment was conducted on “Response of inorganic fertilizers, wheat residue and rhizobium soil health yield attributes Green gram (Vigna radiata L.) var. Samrat” at research farm Soil Science Agricultural Chemistry, design laid out in randomized block (RBD) with three replications. taken for study recommended doses fertilizers (N, P2O5 K2O @ 20, 40 20 kg ha-1) applied rhizobium. The variet...

this research investigate the potential of rhizobium leguminosarum b.v .phaseoli to improve growth and nutritional status of common bean (akhtar cultivar) at three levels of salinity of s0, s1 and s2 (0, 35 and 70 mm sodium chloride, or 0, 3 and 6 ds/m, respectively). the greenhouse experiment was conducted as a factorial design in randomized completely with three replications by using the ster...

The cell density dependence of stationary-phase survival of Rhizobium leguminosarum has been investigated. Following starvation by exhaustion of carbon or nitrogen, but not of phosphorus, the survival of cultures was dependent on the cell density at entry into stationary phase. High-density cultures survived with little or no loss of viability over a 20-day period in stationary phase. In contra...

The objective of this study was to evaluate the exopolysaccharide (EPS) production by Rhizobium leguminosarum cultivated in wastewater generated by oil companies (WWOC1 and WWOC2) and fish processing industry (WWFP). The results obtained in Erlenmeyer flasks indicated that the rhizobial strain grew well in industrial wastewater. Generally, wastewater composition affected the growth and the EPS ...

An in vitro study was conducted to determine the effects of the superior indole-3-acetic acid (IAA) producing Rhizobia and treatments of Ag and Ltryptophan (Trp) on wheat growth indices. Nine strains with different ability of IAA production (belonging to genus Rhizobium leguminosarum var. phaseoli and Rhizobium leguminosarum var. viciae, Sinorhizobium meliloti) and a non-inoculated control; two...
