In this study, the effects of boron doses (0=control, 5, 10, 20 mM) and the application of some beneficial rhizobacteria (Azospirillum lipoferum, Bacillus megaterium, Frateuria aurentia) on the physiological and biochemical parameters of medicinal sage (Salvia officinalis L.) were investigated. The study was carried out in factorial order, in a completely randomized experimental design with four replications, in a controlled climate chamber. In the study, chlorophyll a, chlorophyll b, total chlorophyll, total carotenoid, total anthocyanins, nitrogen balance index, MDA, relative water in leaf tissues, ion leakage, membrane durability, total phenolic substance, total flavonoids, and total antioxidant activity were investigated. Depending on the applied boron doses, increases were observed in total phenolic, total flavonoid, total carotenoid, ion leakage, and MDA values. In contrast, decreases in the nitrogen balance index and membrane durability were observed. It has been determined that PGPR applications effectively reduce the damage caused by boron by increasing the total anthocyanin, total flavonoid, chlorophyll b, total chlorophyll amounts, and membrane durability, and by contributing to the decrease of MDA values compared to the control.
