Correlation matrix of hydraulic xylem characteristics with numerical leaf traits and parameters of stomatal control.

The correlations were calculated from linear model analyses between functional leaf traits and the extracted physiological parameters. Significant relationships are shown in bold letters. 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, MEANROUND = the mean roundness of conducting vessels, and DHYD the hydraulically weighted diameter of conducting vessels.Correlation matrix of hydraulic xylem characteristics with numerical leaf traits and parameters of stomatal control.
