Influence of experimental treatments on mean pedunculate oak seedling (a), shoot (b), leaf (c) and root (d) dry mass (g), twice in the first and at the end of the second growing season. Means with the same letter are not significantly different between treatment at the same time (p < 0.05 ANOVA followed by Tukey HSD test). Means shown in figures are average of all provenances. The vertical lines represent ±1 standard error of the mean. (See first figure for explanations)
