    DETERMINATION OF THE EFFECT OF PLANT GROWTH PROMOTING BACTERIA ON WHEAT (TRITICUM AESTIVUM L.) DEVELOPMENT UNDER SALINITY STRESS CONDITIONS
    (Corvinus Univ Budapest, 2019) Sogut, S.; Cig, F.
    This study was carried out in Field Crops Department Laboratory of Siirt University, Faculty of Agriculture (Turkey) in 2016. In the study, Ceyhan 99 bread wheat cultivar was used. It was aimed to determine the effect of TV14B Stenotrophpmonas maltophilia P (phosphate solubilizing bacteria), TV119E Bacillus-GC group P (phosphate solubilizing bacteria), TV83D Bacillus atrophaeus N (nitrogen fixing bacteria), TV54A Cellulomonas turbata N (nitrogen fixing bacteria), TV113C Kluyvera cryocrescens NP (nitrogen fixing + phosphate solubilizing bacteria), TV83D B. atrophaeus + TV119E Bacillus-GC group (binary combination) bacterial strains on development of Ceyhan-99 bread wheat cultivar under salinity stress. The germination rate (%), germination percentage (%), plant height (cm), root length (cm), plant wet weight (g), plant dry weight (g), nitrogen amount in the soil (%) and phosphorus amount in the soil (%) were determined with the test conducted. It is concluded that TV14B S. maltophilia P bacteria had positive impacts on plant growth parameters at different salinity concentrations. It was observed that TV119E Bacillus-GC group P bacteria, in 100 mM salt concentration, increased plant height, phosphorus in the soil and dry weight parameters. TV83D B. atrophaeus N bacteria treatment in 125 mM salt concentration increased root length, phosphorus and nitrogen amount in the soil compared to the control treatment. It was observed that treatments of TV54A C. turbata N, TV113C K cryocrescens NP and TV83D B. atrophaeus +TV119E Bacillus-GC group NP bacteria in different salt concentrations increased both phosphorus and nitrogen amounts in the soil. As a result, these bacteria treatments were considered to alleviate the disadvantages of salinity stress.
