Heavy metal pollution, especially arsenic toxicity, significantly impairs plant growth and development. Phenolic acids, known for their antioxidant properties involvement in stress signaling, are gaining increased attention as secondary metabolites with the potential to enhance resistance these stressors. This study aimed investigate effects of different concentrations syringic acid (SA1, 10 μM; SA2, 250 SA3, 500 μM) on growth, photosynthetic parameters, activity lettuce seedlings subjected (As, 100 μM). Arsenic reduced by 56.7%, water content 7.39%, osmotic 26.2% leaves compared control. Conversely, SA1 SA2 treatments mitigated adverse preserved balance plants. However, SA3 treatment led a decrease 18.9% 39.5% As+SA3 groups, respectively, indicating that high-dose SA adversely affected under both control conditions. Exogenous improved photosynthesis, whereas provided milder benefits did not reduce exposure. H2O2 47.3% lipid peroxidation 33.4% seedlings. effectively oxidative enhancing activities key enzymes, such superoxide dismutase (SOD) peroxidase (POX). Moreover, was successful maintaining glutathione (GSH) pool, primarily promoted ascorbate (AsA) regeneration. In conclusion, μM (SA1) identified optimal dose reducing supporting growth. Overall, findings underscore resilience heavy toxicity.
