Changes in the levels of redox potential reported in germinated seeds (A, C, E) and 3-month-old seedlings derived from the seeds (B, D, F) of M. sylvestris (A, B), P. avium (C, D) and P. padus (E, F). In germinated seeds, redox potential level between MC x storage temperature x storage time was compared. In 3-month seedlings, the level of redox potential was measured in leaves and roots. Data are the means ± standard error obtained from three independent experiments with similar results. Statistically significant differences are indicated with different letters among the groups, followed by Tukey’s test for seeds and Dunn’s test for seedlings at p ≤ 0.05.
