图1. 崖豆藤属(左)与买麻藤属(右)木本植物的枝条和叶片脆弱性曲线。实心和空心圆分别代表乔木和木质藤本。树种名称缩写见表1。垂直虚线表示枝条与叶片导水率损失50%时的水势值(P50branch和P50leaf)。

Fig. 1. Branch and leaf vulnerability curves of the woody species in Millettia (left) and Gnetum (right). Filled and open circles indicate tree and liana species, respectively. Species abbreviations are shown in Table 1. Water potential at 50% loss of branch hydraulic conductivity (P50branch) and leaf hydraulic conductance (P50leaf) are indicated by vertical dashed lines. Kleaf, leaf hydraulic conductivity.
