Figure 3.
Diurnal courses of measured and simulated canopy transpiration (Ec; A,C) and gross photosynthesis rates (Ac,gross; B,D). The “Measured” dots present the values calculated from gas exchange measurement. The “Simulated potential” line presents the outcome of model simulation without considering water stress. The “Simulated actual” line in B,D presents the outcome of model simulation considering the estimated Ec as actual available water for transpiration while the effect of water deficiency on stomatal resistance was estimated using Equation (7). Data presented was collected in the first day of N2 in CAN1.The canopy in A,B received sufficient water while water supply in C,D was halved.
