Phytohormones Production by Plant Growth Promoting Rhizobacterial Isolates In Gloriosa superba.L

S. Megala, R. Elango

Abstract :

Phytohormones are plant growth regulators which have stimulatory effects on plant growth. The plant growth promoting rhizobacteria viz., Azotobacter, Bacillus and Pseudomonas isolates obtained in the present study were able to produce IAA and GA3 . The Azotobacter quantity of IAA produced varied from 18.1 to 73.6 µg of 25 ml–1 of oth and GA3 produced varied from 2.43 to 7.10 µg of 25 ml–1 of oth. The Bacillus quantity of IAA produced varied from 15.3 to 69.8 µg of 25 ml–1 of oth and GA3  produced varied from 2.34 to 6.80 µg of 25 ml–1 of oth. The Pseudomonas quantity of IAA produced varied from 18.7 to 78.6 µg of 25 ml–1 of oth and GA3  produced varied from 2.51 to 7.41 µg of 25 ml–1 of oth.
