From: Low intra-tree variability in resistance to embolism in four Pinaceae species
Vulnerability curves for branches (blue lines), trunks (green lines), and roots (red lines) of four conifer species (P. pinaster (a), P. menziesii (b), P. sylvestris (c), C. atlantica (d)) showing mean values of the PLC (loss of hydraulic conductivity in xylem, %) as a function of xylem pressure (MPa). The shaded bands represent the standard errors. n branch = 81:61:6, n trunk = 65:30:24, and n root = 14:9:3 for P. pinaster, P. menziesii, and P. sylvestris, respectively. For C. atlantica, only branches (n = 6) and trunk baguettes (n = 4) were measured
