一个形态学上明确的数值模型，用于分析单个根系吸水的导体网络的基础上，与特定的导体代表离散根段的轴向或径向电导率。测定了沙漠龙舌兰（Agave deserti Engelm）根系的导水率（Lp; ms-1 MPa-1）。和仙人掌（Opuntia ficus-indica（L.）米勒通过施加部分真空的近端切除根在溶液中。L p也被测量为40- 80-mm段沿着一个根，随后通过测量轴向传导率和计算径向传导率（.）
A morphologically explicit numerical model for analysing water uptake by individual roots was developed based on a conductor network, with specific conductors representing axial or radial conductivities for discrete root segments. Hydraulic conductivity (L p ; m s -1 MPa -1 ) was measured for roots of Agave deserti Engelm. and Opuntia ficus-indica (L.) Miller by applying a partial vacuum to the proximal ends of excised roots in solution. L p was also measured for 40- to 80-mm segments along a root, followed by measurements of axial conductivity and calculation of radial conductivity (...)
