Values are means for each factor or treatment (n = 3) ± SEM. Different lowercase letters within columns indicate significant differences (Fisher’s LSD, p ≤ 0.05). a p(UV-B), p(ABA) and p(WD): effects of UV-B, ABA and WD, respectively; p(UV-B ×ABA), p(UV-B × WD), p(ABA × WD), and p(UV-B ×ABA × WD): interaction effects of factors. p-values ≤ 0.05 were considered statistically significant, and are in bold.
