Fig. 3. Comparison of observed (data adapted from references) and simulated net leaf photosynthesis using default CROPGRO photosynthetic equations. (a) Griffin and Luo (1999) for plants grown in 350 µmol CO2 mol–1; (b) Griffin and Luo (1999) for plants grown in 700 µmol CO2 mol–1; (c) Valle et al. (1985); (d) Sims et al. (1998); (e) Harley et al. (1985) (at high light, PPF > 2000 µmol photon m–2 s–1); and (f) Harley et al. (1985) (at low light, PPF 
800 µmol m–2 s–1). Solid lines show linear regression, and dashed lines show the 1:1 line.
