Abstract:

Rhizobacterial strains having plant growth promoting hormone can helps in promoting plant growth and mitigates adverse conditions. Keeping in view of their positive impact, present study was undertaken to identify the Salt Tolerant Rhizobacteria (STR) having IAA production activity. Out of 300 bacteria from the mustard rhizospheric soil 25 could able to grow at 10% NaCl medium termed as STR were assessed for their plant growth promoting hormones. Bacterial strains (STR PGP) B1, B14, B17 and B25 identified as genus Enterobacter showing IAA production ranges from 1 - 3 µg/ml. The seeds of salt sensitive mustard (var. Rohini) treated with these STRP GP were sown in pots subjected to salt stress (5M) along with untreated control without salt and STRPGP. At flowering stage, plant vigour and nutritional status was assessed that results an increased value of chlorophyll and flavonol in salt stressed plants as compared to control, while anthocynin remained almost same. The role of STRPGP under salt stress along with increased above parameters indicated the improved ability of mustard to sustain normal growth when subjected to stress condition.
