Clonal means of the negative of the applied air pressure that caused 12% loss of hydraulic conductivity (Ψ12) related to clonal means of total above-ground biomass (BM; a), stem diameter (SD; b), tracheid length (TLEW; c) and latewood percentage (LWP; d). Clonal means of the percent loss of conductivity induced by an applied air pressure of 4 MPa (PLC4MPa) related to clonal means of the thickness of tangential cell walls of the first earlywood tracheids (WEW; e) and latewood percentage (f). Different symbols indicate different clones and error bars represent one standard error. The correlation coefficients of the linear or quadratic model equations are marked with a single asterisk (*) if significant at the 5% level and with two asterisks (**) if at the 1% level.
