Effects of salinity stress on biochemical biomarkers activity of inoculated wheat by plant growth promoting bacteria (Azotobacter chroocccum, Azospirillum lipoferum, Pseudomonase putida) and humic acid

Effects of salinity on growth and changes biochemical biomarkers activity in wheat inoculated with Plant growth promoting bacteria and humic acid, an experiment was conducted in 2010 at research greenhouse, Faculty of Agriculture and plant breeding, Islamic Azad University of Karaj Branch. A completely randomized design with three replications was using analysis of factorial. experimental treatments included two levels of humic acid {(A0): control, (A1): humic acid consumption}, and salinity levels in the three levels of {(B0): Control, (B1): Low salinity of 75 mM, (B2): high salinity of 150 mM}, the use of microorganisms in the five levels of {(C0): Control, (C1): grain inoculation with Azospirillum lipoferum, (C2): grain inoculation with Azotobacter chroocccum, (C3): grain inoculation with Pseudomonase putida, (C4): the mix grain inoculation with (Azotobacter chroocccum, Azospirillum lipoferum, Pseudomonase putida)}.The results showed the effect of grain inoculation with plant growth promoting bacteria and humic acid consumption during exercise salinity on Grain yield, Malondialdehede, Dityrosine and Dihydroxy guanosine was significant.The highest grain yield of treatments inoculated with Azetobacter chroocccum bacteria and humic acid no consumption and the salinity was 75 mM, and Most of Malondialdehede with the treatment non grain inoculation with plant growth promoting bacteria and Humic acid consumption and salt stress of 150 mM was. And Most of Dityrosine with the treatment non grain inoculation with plant growth promoting bacteria and humic acid no consumption and salt stress of 150 mM was, while the highest Dihydroxy guanosine with the Pseudomonase putida and Humic acid consumption and salt stress of 150 mM was.
