tailieunhanh - Characterization of rhizobium isolates and their potential PGPR characteristics of different rhizosphere soils of Telangana region, India

In this study, 47% Rhizobial isolates showed phosphate of the isolates showed IAA production and 100% for ammonia, 53% for siderophores and 53% isolates showed for HCN production. | 2017 6 5 2808-2813 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 6 Number 5 2017 pp. 2808-2813 Journal homepage http Original Research Article https Characterization of Rhizobium Isolates and their Potential PGPR Characteristics of different Rhizosphere Soils of Telangana Region India K.

Gowri Priya Department of Agricultural Microbiology and Bioenergy College of Agriculture Professor Jayashankar Telangana State Agricultural University Rajendranagar Hyderabad-500030 India Corresponding author ABSTRACT PGPR function in three different ways synthesizing particular compounds for the plants facilitating the uptake of certain nutrients from the soil and lessening or preventing the Keywords plants from diseases. Some of Plant growth promoting characteristics such as phosphate Rhizobium PGPR solubilisation Indole acetic acid IAA capacity ability to produce ammonia NH 3 as sole Rhizospheric nitrogen source siderophore production and production of hydrogen cyanide were Heavy metals evaluated in fifteen Rhizobacteria isolated from different rhizosphere soils of groundnut sunflower maize black gram green gram rice soy bean and redgram. In this study 47 Article Info Rhizobial isolates showed phosphate of the isolates showed IAA Accepted production and 100 for ammonia 53 for siderophores and 53 isolates showed for 26 April 2017 HCN production. All the fifteen isolates were examined for the potential to inhibit two Available Online fungal pathogens viz. Rhizoctonia solani and Sclerotium rolfsii under in vitro conditions. 10 May 2017 Out of fifteen isolates only 3 isolates exhibited inhibition potential against two soil borne plant phytopathogen Among these isolates RR-1 and GNR-1 were tolerant to all the heavy metals 100 μg ml-1 .
