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

Table 3

Comparisons of soil moisture conditions (volumetric water content) in the trial pots between lower and higher irrigation treatments for all three tree species (n = 10, per species). Presented are mean values with standard deviation. Uppercase letters indicate significant differences using t-test (F. sylvatica: p = 0.003, df = 13; A. pseudoplatanus: p = 0.028, df = 18; C. betulus: p = 0.079, df = 18).

Trial pot species	Soil moisture (% v v^-1)
	Lower irrigation	Higher irrigation
Fagus sylvatica	18.9 (± 2.2)^A	24.6 (± 4.3)^B
Acer pseudoplatanus	21.6 (± 3.9)^A	25.3 (± 3.0)^B
Carpinus betulus	19.6 (± 2.4)^A	22.4 (± 4.3)^A
