In this study, the effects of plant development-promoting bacteria (Bacillus cereus RCP 3/1 + Rhizobium radiobacter RCR 11/2) (including the aminocyclopropane carboxylate deaminase enzyme) and different salt stress conditions (0, 30, and 60 mM/L NaCl) on the San Andreas variety of strawberry were studied on a number of harvest days. Some biochemical changes due to mycorrhizal fungus applications (including some Glomus species) were investigated as well. In the trial, as salt concentration increased, total phenolics and lipid peroxidation (malondialdehyde (MDA) content) increased compared to the control. The effects of salt concentration and experimental applications on total phenolic content reached their maximum on day 45, while their effects on MDA reached a maximum on day 30. In terms of applications, the mycorrhizal application decreased both total phenolics and MDA content. When the interaction of salt and applications was examined, the highest MDA content (3.568 mu M g(-1) FW) and total phenolics amount (0.343 mg g(-1)) were observed with the 60 mM/L NaCl concentration in the control application. The results indicate that the arbuscular mycorrhizal fungi were capable of alleviating the change in biochemical contents caused by salinity stress on the strawberry plants.
