Chlorophyll a levels A, chlorophyll b levels B, chlorophyll a/b ratio C, total chlorophyll levels D, total carotenoid levels E, and Soil Plant Analysis Development (SPAD) values (F) in A. rugosa under different ozonated water treatments (0, 1, 10, 20, 40, and 80 s at 1 µmol mol−1). Each value indicates the mean ± SE of three samples (n = 3). Different letters represent the significant differences at p ≤ 0.05, as assessed using ANOVA, followed by Tukey’s multiple range test
