Bacterial strains obtained from the rhizoplane, histoplane and phylloplane of Achyranthus aspera (RAa1, RAa2, HAa1, HAa2, HAa3, PAa1, PAa2, PAa3, PAa4, PAa5, PAa6), Euphorbia heliscopia (REh1, REh2, HEh1, HEh2, PEh1, PEh2), and Malvestrum tricuspidatum (RMt1, HMt1, HMt2, PMt1, PMt2) were used to inoculate the seeds of Triticum aestivum var. Inqlab-91. Inoculated as well as uninoculated seeds were germinated and grown under 0 and 100mM NaCl stress for 10 days. Different growth parameters and some biochemical characters were considered for these studies. Salinity reduced the percentage germination, root, shoot, seedling length as well as fresh weight per seedlings, whereas it increased the dry matter accumulation, Na+, K+ uptake, protein, auxin content and activity of peroxidases and acid phosphatases in uninoculated seedlings. While the association of many bacterial strains with wheat enhanced the seedling growth under 0 and 100mM NaCl stress. Bacterial inoculations improved different growth parameters by reducing the Na+ uptake and improving the protein content, auxin production and alteration in enzyme activities., Bacterial strains obtained from the rhizoplane, histoplane and phylloplane of Achyranthus aspera (RAa1, RAa2, HAa1, HAa2, HAa3, PAa1, PAa2, PAa3, PAa4, PAa5, PAa6), Euphorbia heliscopia (REh1, REh2, HEh1, HEh2, PEh1, PEh2), and Malvestrum tricuspidatum (RMt1, HMt1, HMt2, PMt1, PMt2) were used to inoculate the seeds of Triticum aestivum var.
