Influence of K supply on ABA homeostasis in flag leaves of barley during terminal drought stress. Concentrations of (A) abscisic acid (ABA), (B) phaseic acid (PA), and (C) dehydro-phaseic acid (DPA) in flag leaves of the lines HPR and LPR. Plants were pre-cultured under sufficient water supply (control) or water limitation (stress) and under low or high K supply. Flag leaves from 12 weeks-old plants were harvested 12 days after imposing drought stress. Bars indicate mean ± SD. Different letters denote significant differences according to three-way ANOVA and Tukey’s test (p < 0.05; n = 6).
