**4. Conclusions**

The results revealed that exogenous SA application minimized the adverse effects of chilling in local mango transplants of the "Seddik" cultivar, as evidenced by reduced membrane damage and enhanced endogenous production of photosynthetic pigments, total sugar, and DPPH. SA also reduced the content of total phenolic compounds and proline and regulated the activity of antioxidant enzymes, including SOD, CAT, PPO, and POX, especially during the recovery period. These findings suggest that exogenous SA treatment can help mango transplants recover from chilling stress damage.
