Mean of responding explants (%), significance and sample size (n) are presented in different columns. For each factor, mean of responding explants is expressed as a percentage (±SE) relative to the total amount of cultured explants. aDifferent letters among the levels of each of the three factors indicate significant differences between them (p < 0.05) according to non-parametric Kruskal-Wallis and pairwise Wilcoxon tests.
