Abstract: | This experiment was conducted to investigate the impact of foliar spraying salicylic acid (SA) and methyl Jasmonate (MJ) on the physiology responses of strawberry (Fragaria × ananassa cv. ‘Camarosa’) grown under salinity stress. According to results, SA and MJ significantly reduced the injuries caused by salt stress, possibly through promoting K+ accumulation as well as decreasing the electrolyte leakage and Na+ contents in the leaves. The best protective effects resulted from 0.75 mM SA and 0.25 mM MJ treatments. These results indicate that SA and MJ can effectively improve the defense system and antioxidant capacity of strawberry in the salt affected environments. |
