图1. 三种植物自然和人工生境水力功能性状图(平均值±标准误)。A, 比导率(K_s)。B, 栓塞抗性(导水率损失50%时的水势, P₅₀)。不同小写字母表示种内差异显著(p < 0.05)。

Fig. 1. Hydraulic functional traits of three species in field and garden habitats (mean ± SE). A, The specific hydraulic conductivity (K_s). B, Embolism resistance (water potential at 50% loss of conductivity, P₅₀). Different lowercase letters indicate significant differences within species (p < 0.05).
