Physiological characterization of wild type (Lukullus and Ailsa Craig) and their respective ABA-deficient isogenic lines notabilis and flacca tomato plants subjected to soil flooding: gas exchange parameters along with leaf water potential and leaf relative water content (A) and hormonal profiling in shoots and roots (N = 4) (B). Bars in white and blue are control and flooded groups, respectively. Data are mean values of (N = 5) independent measurements. Statistical differences were assessed following a two-way ANOVA using genotype and treatment as factors. Different letters denote significant differences between means at p ≤ 0.05 after a least significant difference post hoc analysis. ns, non-significant comparisons.
