Table 3.

Water use of three Quercus species over three days under greenhouse conditions.

Species	Height (cm)	seedling-1	Average daily water use (g day ⁻¹)
Species	Height (cm)	seedling-1	leaf area (cm-2)	Height-adjusted (cm-1)^{^z}
Q. cerris	45.3A^{^y}	47.5A	0.091A	1.4B
Q. pubescens	46.0A	44.9A	0.111B	1.3A
Q. robur	70.5B	73.4B	0.084A	1.3A

↵^zHeight-adjusted water use was calculated by dividing the average daily water use by seedling height.
↵^yMeans within a column followed by different letters are significantly different from each other at the α = 0.05 level using the Student-Neuman-Kuels test. Each value is the mean of 72 plants.
