Abstract
Plant-growth promoting rhizobacteria (PGPR) elicit activation of phenylpropanoid pathway in plants which leads to phenolics production and enhanced antioxidant capacity. The purpose of this work was to assess the antioxidant activity of soybean plants, Glycine max L., inoculated with PGPR (isolates of Azotobacter chroococcum, Streptomyces sp. and mixture of these) during plant development, as well as yield of inoculated soybean plants. PGPR applied in the experiment stimulated flavonoids and isoflavone synthesis, which enhanced non-enzymatic antioxidant ability of soybean plants. Also, PGPRs stimulated accumulation of daidzein and genistin in soybean seedlings (5-fold and 2-fold compared to control values, respectively). The mixture of PGPRs showed positive impact on antioxidant activity (10-20% higher activity) and yield components of soybean which proposed this inoculum as possibly potent bio-fertilizer in soybean production.
