Inqlab 91. Certified seeds of Triticum aestivum var. Inqlab 91 were inoculated with monocultures (ST-1, ST-2, ST-3, ST-4, rhizosphere bacteria; HT-1, HT-2, HT-3, histoplane bacteria) and different combinations of mixed cultures of bacteria. Inoculated and non-inoculated seeds were germinated and grown under NaCl stress (0, 100 mM NaCl) for 10 days. After that growth measurements (length and weight parameters) were taken and Na+/K+ contents, soluble protein content, auxin content and enzyme activities (peroxidase and acid phosphatase) were determined. Generally, with the application of NaCl, reduction in germination and growth parameters, whereas increase in Na+/K+ contents, auxins content, soluble protein content as well as enzymes activities were observed. Bacterial inoculations stimulated germination and growth, over non-inoculated respective treatments, especially under saline conditions. Mixed culture inoculation with rhizosphere bacteria (some combinations) and histoplane bacteria was more effective in stimulating seedling growth than monoculture inoculations at 100 mM NaCl. Bacterial inoculations also enhanced fresh weight per seedling, auxin, soluble protein and K+ contents of seedlings. Whereas decreases in dry weight accumulation, Na+ content and activity of enzymes, at 100 mM NaCl with bacterial inoculations were recorded. From these results improved growth of seedlings could be related with increased auxin content but decreased dry weight increment, Na+ content and enzyme activities.]]>Acharya, U.T., L. Prakash and G.
