Figure 2. Variation in morphological traits during the time course of drought hardening. The evolution of height (A), stem diameter (B), leaf area (C) specific leaf area (D), plant (E), leaf (F), root (G) and stem biomass (H) of E. globulus plants in response to three drought hardening treatment (-0.2, -1.3 and -2.4 MPa) were evaluated. Error bars represent ± 1 SE, n = 20.
