Abstract

Wheat (Tritium aestivum) is the primary food of Pakistan.Salinity is a blockade towards growing a sustainable food production system and necessitates environment management. Plant growth promoting rhizobacteria can ameliorate abiotic stressors through induced salt tolerance. PGPR having ACC deaminase activity can improve plant performance by minimizing the effects of ACC and endogenous ethylene that limit plant growth under salt stress. Plants grown from seeds inoculated with PGPR strains having ACC deaminase are comparatively more tolerant to salt stress. The study was carried out at Soil Salinity Research Institute, PindiBhattian to investigate the impact of PGPR (Plant growth promoting Rhizobacteria) on wheat grown in salt affected field. The design was Randomized complete block with three replications. Wheat seeds Cv. Faisalbad-2008 were inoculated with rhizobacteria strains which were: Thal-8, WM-14 and WM-10 during 2015-16 Inoculation with rhizobial strains that provide ACC-deaminase activity proved a useful move toward for alleviating the stress induced by ethylene and accordingly improving the growth and yield of wheat in the presence of high salinity stress. Decline in sodium uptake following seed inoculation with different rhizobial strains for wheat grown on salt- affected lands is a constructive possibility to reclaim salt stress biologically.
