Paddy physiology and enzymes level is regulated by rhizobacteria under saline stress
Abstract
To investigate the physiological basis of salt adaptation in paddy due to inoculation with plant growth promoting bacteria, we compared their effect in paddy under saline and non-saline condition on root length, chlorophyll content, relative water content, stomatal conductance, membrane stability index and change in ascorbate peroxidase and nitrate reductase activities. In a pot experiment, the effect of endophytic and rhizospheric bacteria was studied in a local paddy rice (Oryza sativa L.) variety GJ-17 under salt stress. Our findings suggest that inoculation with Pseudomonas pseudoalcaligenes and Bacillus pumilus resulted in change of ascorbate peroxidase, nitrate reductase activity and plant growth parameters such as root length, chlorophyll content, RWC, stomatal conductance and membrane stability index under salinity. Mixture of both Pseudomonas pseudoalcaligenes and Bacillus pumilus revealed better response in paddy against the adverse effects of salinity.
