Experimental Study of Environmental Effects: Leaf Traits of Juvenile Fagus sylvatica, Acer pseudoplatanus, and Carpinus betulus Are Comparable to Leaves of Mature Trees in Upper Canopies

Figure 2

Specific leaf area (SLA) of (a) Fagus sylvatica (n = 20), (b) Acer pseudoplatanus (n = 15), and (c) Carpinus betulus (n = 18) for the different treatments in the greenhouse experiment. Boxplots are marked with uppercase letters indicating significant differences or with “n.s.” for nonsignificant differences using (a) Kruskal-Wallis and post hoc test (p < 0.05; df = 3) and (b-c) ANOVA and Tukey’s HSD (p < 0.05, df = 3). Treatments: LTLW, lower temperature and lower irrigation; LTHW, lower temperature and higher irrigation; HTLW, higher temperature and lower irrigation; HTHW, higher temperature and higher irrigation.
