Figure 6

Factors affecting the simulated increase in grain yield due to E-[CO2] in the high N treatment in the FACE experiments at two sites. (a) grain yield increase versus biomass increase, (b) grain yield increase versus harvest index increase, (c) biomass increase versus primary [CO2] increase (leaf CO2 assimilation rate, CAR, or radiation use efficiency, RUE), and (d) biomass increase versus maximum LAI increase. The data from all N treatments and the chamber experiments are shown in Figures S6–10. LRC, light response curve-type photosynthesis model; FvCB, Farquhar, von Caemmerer & Berry photosynthesis model; RUE, radiation use efficiency. SZ = Shizukuishi, WX = Wuxi.
