摘要

Development of improved crop production technologies having less or no harmful effects on environment, has become centre to mitigate salinity stress. Soil salinity hampers crops productivity by elevation of ethylene level in plants which can be decreased by activity of ACC deaminase. Despite reduction of salinity stress produced ethylene by inoculation of single strain ACC deaminase producing PGPR, multistrains inoculation with inorganic fertilizer could be more effective. So far, single-strain seed inoculation with ACC deaminase producing PGPR to improve crop growth under stress conditions has been widely investigated. However, the current study was conducted to examine the efficacious role of multi-strain PGPR inoculation in the presence of recommended mineral fertilizer (RNPKF) on wheat growth under artificially induced salinity stress. The multi-strain PGPR, Enterobacter cloacae (W6), Serratia ficaria (W10) and Burkholderia phytofirmans (PsJN) with mineral fertilizers significantly increased root (40%) and spike length (54%), root (65%) and shoot (63%) dry weight in wheat as compared to control and even single-strain inoculation. A significant improvement in straw (0.96-fold), economic (1.69-fold), biological yields (1.20-fold), phosphorus concentration in grain (1.43-fold) and shoot (1.75-fold) as compared to control validated the use of multi strain inoculation with mineral fertilizers, as an effective and environmentally safe technique to improve resistance to wheat plants against salinity.
