Regression equations for all significant correlations of Ψ50 and KS to the functional traits.

The correlations were calculated from linear model analyses. Ψ50 = xylem pressure at which 50% loss of the original maximum specific xylem hydraulic conductivity occurred, KS = specific hydraulic conductivity of the xylem, b = slope of the three-parametric sigmoid model of the vulnerability curve, CONMEAN = mean gs; CONMAX = mean gs max; VPDMax = VPD at gs max; CONMAXFIT = modeled gs max; VPDMaxfit = VPD at modeled gs max, and VPDPoi = VPD at the point of inflexion of the gs ∼ VPD curve, MEANAREA = the mean area of conducting vessels, and DHYD the hydraulically weighted diameter of conducting vessels.Regression equations for all significant correlations of Ψ50 and KS to the functional traits.
