Exploitation of pseudomonads for their plant growth-promoting traits
Author(s): Sangita Sahni and Bishun Deo Prasad
Abstract: The present study was conducted to characterize the 30 native plant growth promoting (PGP) bacteria from different pulse crops rhizosphere grown in BHU, Varanasi, India. All the 30 isolates were screened in vitro for PGP characteristics. Among them, 12 were produced fluorescent pigments on Kings’ B medium, P1 and C4 were best in producing IAA (11.37 and 5.75 mg/l, respectively), whereas PSB1 and PSB2 solubilized highest amount of tri-calcium-phosphate (502.39 and 395.45 mg/l, respectively), while C4 and CRM3 were strongly cyanogenic. In addition to it, PUR46 was also found to be positive in other growth promoting traits like phosphorus solubilization and ammonification. The results suggested that solubilization of tri-calcium phosphate might be helpful in enhancement of plant growth.
