Abstract:

Rhizosphere, phylloplane and caulosphere is the region where a complex community of microbes, mainly bacteria and fungi are present. The microbe plant interaction in these regions can be beneficial, neutral, variable, or deleterious for plant growth. The bacteria that exert beneficial effects on plant development are termed plant growth promoting bacteria. To quantify the amount of phosphate solubilizing bacteria from rhizosphere, phylloplane and caulosphere of brinjal (Solanum melongena L.). Materials and methods: Brinjal (Solanum melongena L.) plants of different varieties were collected from seven locations around Bangalore viz., Hessaraghatta, Yelahanka, Kengeri, Madi vala, Hebbal, Tirumalapura and Attibele were also screened for the presence of phosphate solubilizing bacteria. Nitrogenase activity was estimated by acetylene reduction assay and analyzed by gas chromatography. The amount of nitrogen fixed brinjal bacterial isolate was quantified by micro Kjeldhal method. The amount of nitrogen fixed by the BBI was equivalent to 23.5 nm of C2H2 reduced/tube/hour. The amount of nitrogen fixed by the BBI showed a steady increase upto three days (75 nm of C2H2 reduced/tube/hour) after which there was a decline in the amount of nitrogen fixed by the microbe. Phosphate solubilization by the bacteria isolated from brinjal is highly beneficial to the crop, as it would always make more phosphate available to the crop. This phosphate solubilizing potential could be harnessed to reduce the input of inorganic fertilizers. For the first time the presence of phosphate solubilizing bacteria on the rhizosphere and endorhizosphere of brinjal (Solanum Melongena L.) cultivars was established.
