Abstract :Plant growth promoting rhizobacteria (PGPR), which have environmentally friendly properties, are important for their use as biofertilizers and biocontrol agents. The aim of this study was to determine the effects of single and combined applications of PGPR bacteria on maloninaldehyde (MDA), proline, superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) activities of leaves in Albion and Monterey strawberry varieties. Bacillus subtilis OSU-142 (B. subtilis OSU-142), Bacillus megaterium M3 (B. megaterium M3) and Paenibacillus polymyx (P. polymyx) were used as PGPR in the study. The effect of rhizobacteria varied according to strawberry varieties. Rhizobacteria applications showed positive effects on MDA, SOD and POD. However, rhizobacteria treatments did not have a significant effect on proline, while they showed a varying effect on CAT according to the varieties. In this study, significant results were obtained on the effects of strawberry and rhizobacteria application on biochemical activity and enzymatic activity. The results of this study may provide important clues for future studies on similar subjects.
