FIGURE 4.

Ion profiles of Solanum lycopersicum var. Red Setter plants treated with omeprazole. Plants were grown in a hydroponic solution containing 0, 1, 10, or 45 μM OP, with and without 200 mM NaCl. Plants were harvested after 2 weeks of salt treatment (50 DAS, 14 DSS) and used for ion analysis. Values for K⁺ (A), Na⁺ (B), Na:K ratio (C), Ca²⁺ (D), Cl^-(E), and NO3^-(F) are shown. Values indicate average ± SE (n = 6). Different letters indicate significant differences at P < 0.05 between an OP treated sample and the corresponding untreated control.
