Changes in the levels of hydrogen peroxide (H₂O₂) reported in germianted 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, the level of H₂O₂ interaction between MC x storage temperature x storage time was compared. In 3-month seedlings, the level of H₂O₂ 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 germinated seeds and Dunn’s test for seedlings at p ≤ 0.05.
