| Summary: | 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. [Projekat Ministarstva nauke
