Effect of increasing maximum stomatal conductance on daily water use efficiency. g1 is a parameter characterizing the maximum stomatal conductance. (A) Daily WUE for different values of g1 for a cucumber leaf during the recorded sunny and cloudy days. (B) Total daily transpiration rate (FO) and daily net assimilation rate (Anet) for different values of the maximum stomatal conductance. Simulations were performed per second over 15 h (from 06:00 a.m. to 9:00 p.m.). Values of g1= 3.51 was increased from −40 to 90% and each point on the figure is 1 day simulation result. Other climatic data were extracted from the 2 days measurement data presented in Figure 1 and all other parameter values are summarized in Tables 1, 2.
