Abstract

One of the ways to struggle with salinity is bioremediation by using microorganisms of tolerant to salinity for amend saline soils. The aim of this study was to investigate the effect of growth promoting bacteria, mycorrhizal and endophyte fungi on wheat under saline conditions. The experiment carried out as a completely randomized design (CRD) with two factors, microbial factors (4 levels) and salinity (3 levels) in three replications. Plants harvested after 60 days. Results showed that the main effect of salinity levels and microbial inoculation was significant on all measured parameters. The interaction of salinity levels and microbial inoculation was not significant on the measured parameters. Among microbial treatment, bacteria treatment had the greatest effect on height, fresh and dry weight of shoot and fresh and dry weight of root (1.18, 1.35, 1.64, 1.60 and 1.74 times) compare to control, respectively. In general, it can be deduced that the use of growth promoting microorganisms improve plants growth indices in saline conditions.
