图4. 水力性状与旱季叶片气体交换速率之间的相关关系。A、B, 旱季最大净光合速率(A_max)与叶比导率(k_l)和叶片水力导度(K_leaf-max)之间的相关性; C、D, 枝-叶脆弱性分段(P_{50leaf-branch})与旱季最大净光合速率(A_max)和气孔导度(g_s-max)之间的相关关系。误差线为标准误差。

Fig. 4. Relationships between maximum net photosynthetic rates during the dry season (A_max) and leaf specific hydraulic conductivity (k_l)(A), or maximum leaf hydraulic conductivity (K_leaf-max)(B), and relationships between the difference in P₅₀between leaves and branches (P_{50leaf-branch}) and A_max (C) or maximum stomatal conductance during the dry season (g_s-max)(D). Error bars are standard errors.
