Acetate acts as one of the most important intermediates in cellular metabolism. To evaluate the role of acetate sources in salinity stress, strawberry transplants treated with different acetate sources including ammonium acetate and acetic acid (1 mM) and ammonium carbonate (0.5 mM) in two saline stress (40 mM NaCl) and no- stress conditions. Salinity stress reduced biomass in strawberry, but the least change in biomass was observed in acetate treatments. The highest leaf water content was observed in acetic acid and control treatments under salinity stress. Salinity caused a change in vitamin C content of the fruit, and the highest contents were observed in acetic acid treatment and the lowest salinity stress alone (86.33 and 42.50 mg/100 g FW, respectively). The highest yield per plant was in acetic acid treatment and the lowest in ammonium carbonate and salinity treatments alone. Potassium to sodium ratios was higher in plants treated different sources of acetate compared to other treatments without acetate application Overall, acetate, especially acetic acid treatment at 1 mM, can improve tolerance to salinity stress conditions in plants. On the other hand, the lower reduction of yield in salinity stress conditions is another positive feature of this treatment. Therefore, it can be considered as one of the cheapest and simplest compounds to increase stress tolerance, especially in salinity stress conditions in strawberries.
