pyhelios.PlantHydraulics.HydraulicConductance Class Reference

Hydraulic conductance of a leaf, stem or root as a function of water potential. More...

Detailed Description

Hydraulic conductance of a leaf, stem or root as a function of water potential.

Conductance follows K = saturated_conductance / (1 + |psi / potential_at_half_saturated|^sensitivity). It is constant at saturated_conductance when potential_at_half_saturated or sensitivity is zero.
