Fig. 2: Frequency distribution of the diameter (µm) of xylem vessels (light gray) and their relative contribution to total hydraulic conductivity (dark gray) of two shared species of the study sitesMitraria coccinea (left) and Hydrangea serratifolia(right). The frequency distribution is significant different for diameter of xylem vessel and relative contribution to total hydraulic conductivity, as shown by the Kolmogorov-Smirnov test (Xylem vessel for the specie Mitraria coccinea sp ., in Nahuelbutap =0.002, in Puyehue p =0.01, and Aysén p =0.001; Relative contribution to total hydraulic conductivity for the specieMitraria coccinea sp for Nahuelbuta p =0.01, Puyehuep =0.013, Aysén p =0.001; Xylem vessel for the specieHydrangea serratifolia in Nahuelbuta p =0.003, Puyehuep =0.027, and Aysén p =0.001; Relative contribution to total hydraulic conductivity for the specie Hydrangea serratifolia in Nahuelbuta p =0.04, Puyehue p =0.022, and Aysénp =0.001)
