T
he growth promoting bacteria (PGPR) are group of bacteria mainly found
in the rhizosphere of plant, having capability to stimulate their health and
growth and also defend them from different soil borne pathogens by different
mechanisms. In current study, total thirty-four strains of PGPR were isolated
from the rhizosphere of healthy banana plants and differentiated on the basis
of morphological characteristics and biochemical tests. Phosphate solubilizing
ability, capability of auxin production as well as sideroshore competency of
PGRP were also investigated for the stimulation of plant growth. Out of 34
isolated strains, six isolates were found positive with high siderophore
producing activity, six strains were confirmed having the ability of production
of indole acetic acid (IAA), and 17 isolates were found with excellent ability to
solubilize the insoluble phosphate. As enzymatic production seemed to have
a significant role in inhibition of different pathogens of plants, most of the
isolates in current study were found positive for the production of amylases,
oxidase, pectinases, proteases, lipases, catalases. Furthermore, seven PGPR
isolates also showed the antifungal activity with maximum 51.59% and 50.48%
growth inhibition of Fusarium oxysporum
f.sp. cubense
in vitro.
Thus, these
rhizosphere isolates might be used to endorse plant growth and a good
biocontrol for pathogenic fungi in banana growing areas of Pakistan.
