FW under normal sowing conditions, while reducing lipid peroxidation and improving redox balance. Enhanced antioxidant capacity was further supported by higher ferric reducing antioxidant power (4.54 mg TE/g) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (56.1 µmol TE/g) values, particularly in RKD-18. In contrast, thiourea at higher concentration (500 ppm) exhibited inhibitory effects, indicating possible phytotoxicity. Across treatments, RKD-18 consistently outperformed RCr-728, demonstrating superior biochemical and enzymatic resilience. Overall, the study is significant in identifying thiosalicylic acid as an effective and practical foliar elicitor that enhances antioxidant defense and secondary metabolism, thereby improving coriander performance, yield, and quality under variable high-temperature field conditions.
