Experimental factors include two wheat cultivars (Atila and Zagros) and six levels of growth promoting bacteria (Pseudomonas putida strain R168, R159, R112, Azosprillium lipoferum strain 21 and Azetobacter chroococcum strain 5 and a control). Results showed that the highest amount of chlorophyll and soluble sugar in leaf in Zagros cultivar was obtained from bacteria Pseudomonas strains R159 and Azetobacter, respectively, but in Attila cultivar Pseudomonas strains R112 showed the highest chlorophyll and leaf sugar. Most of the membrane stability and carbonil highest amount of protein was obtainrd from Pseudomonas strains R112 and control, respectively. In the Zagros cultivar, the Pseudomonas bacteria, with 3130 kg/ha seed yield than other bacteria was superior and also showed the highest 1000 seed weight but in Attila cultivar although bacterial treatments had a higher seed yield than control, But no significant difference between Azosprillium with R112 and R159 strains. Finally Zagros cultivar showed better respond to bacterial inoculotion and for rainfed conditoin of Germi area cultivation of Zagros cultivar as well as bacteria Pseudomonas strains R112 inoculation is recommended for maximum seed yield. %U https://plantproduction.scu.ac.ir/article_13121_7d968423d8697d0ee9957fef49b4c3a0.pdf
