Table 1.

Morphological traits of hybrid poplar saplings grown under control (‘Light control’), shade, and high humidity (‘High RH’) conditions.

Experimental treatment Height (m) DW R (g) A L (m2) A L:DW R (m2 g–1)
Light control 0.98 (0.03) a 1.14 (0.12) a 0.32 (0.04) a 0.28 (0.01) a
Shade 0.73 (0.03) b 0.61 (0.06) b 0.16 (0.02) b 0.27 (0.02) a
High RH 1.21 (0.05) c 1.61 (0.19) a 0.27 (0.04) a,b 0.16 (0.01) b

The standard error of the mean is given in parentheses, n=5. Different letters indicate significant differences between treatments (P ≤ 0.05). Variables shown are plant height above pots, total root dry weight (DW R), total leaf area (A L), and leaf area to root dry weight ratio (A L:DW R).
