Growth of Rhizobium Strains at Low Concentrations of Phosphate
نویسنده
چکیده
520 efficient. One strain could barely grow at P concentration below 1 μM; this strain could have difficulty colonizing P-deficient soils or normal rhizospheres. Large differences in tolerance to low P among strains may be agronomically important. The technique could be simplified for routine screening of strains; and its operation at submicromolar concentrations could be improved for research on nutrition and requirements of P-efficient rhizobia and other organisms. Additional Index Words: legumes, limonite, microbial nutrition, nodulation, nitrogen.

Abstract: Sulphur dioxide (SO2) is one of the main air pollutants that can cause imbalance in growth and physiological function of plant in high concentrations. Rhizobium-plant symbiosis can cause increasing in plant resistance to abiotic and biotic stresses in addition to increase growth of plant. In this study, effects of Rhizobium (native and standard strains) on leaf anatomical parameter...

Twenty six Rhizobium strains were isolated from root nodules of Sesbania sesban (L.) Merr. collected from different regions of Andhra Pradesh. All the 26 Rhizobium strains produced indole acetic acid (IAA), but maximum amount was produced by only five strains in yeast extract mannitol (YEM) medium supplemented with L-tryptophan. The strains were found to elaborate maximum IAA when fed with 2.5...

Sulphur dioxide (SO2) is one of the major atmospheric contaminant that induces negatively effects in the cellular biochemistry and physiology of the plants. However, Rhizobium inoculation can cause increas in plant resistance to abiotic and biotic stresses. In this study, effects of different concentrations of Sulphur dioxide gas (0, 0.5, 1, 1.5 and 2 ppm) on photosynthetic pigments, proline, p...

Air pollution is the most important environmental problem of last century that threatens the health of living organisms, especially plants. SO2 is one of the main air pollutants that can cause to imbalance in growth and physiological function of plant in high concentrations. Symbiosis of Rhizobium bacteria with alfalfa can cause increasing plant growth and plant resistance to abiotic stresses. ...
