图1. 不同演化类群9种植物的枝条比导水率(K_S)、叶片比导水率(K_L)和叶片水力导度(K_leaf)(平均值±标准误差, n = 3-5)。最右图柱上不同字母是HSD多重比较的结果, 9个物种的系统发育树在柱状图最下方, 物种缩写见表1。Fern, 蕨类植物; Gym, 裸子植物; Ang, 被子植物。

Fig. 1. Comparison of sapwood-specific hydraulic conductivity (K_S), leaf-specific hydraulic conductivity (K_L) and leaf hydraulic conductance (K_leaf) among the nine species from three evolutionary lineages (mean ± SE, n = 3-5). Letters on top of each bar in the right column are HSD multiple comparison results, the phylogenetic tree of the nine species is drawn at the bottom. See species abbrivations in Table 1. Fern, ferns; Gym, gynosperms; Ang, angiosperms.
