From: A rate equation model of stomatal responses to vapour pressure deficit and drought
As the value of the membrane hydraulic conductivity (Lp) increased (resistance to water flow across the membrane decreased) stomatal sensitivity to increased D declined. Values for Lp are 0.5, 1.0 and 2 times the default value for the curves, reading left to right. Changes in membrane hydraulic conductance influence the maximum value of E and alter stomatal sensitivity to D. The dashed lines are lines of constant D.
