Superoxide dismutase (SOD) activity (inhibition rate %) (a) and root ferric chelate reductase (FCR) activity (nmol Fe(II) h−1 g−1fresh weight) (b) for A. thaliana demes A1(+C) and T6(−C) with adequate (+Fe) or deficient (-Fe) iron supply. Values are means ± SE (n = 12; p< 0.05; 2-way ANOVA; Tukey HSD). Solution pH (c) after one-week cultivation of A1(+C) (green) and T6(−C) (orange) under Fe-deficiency conditions; initial pH: 7.5 (blue). Values with different letters are statistically different (n = 16; p<0.05 comparison of means of final pH values by Student’s t test).
