Comparisons between simulated and observed leaf photosynthetic parameters. (A) Light-saturated net photosynthetic rate under PPFD 1300 µmol photons m⁻² s⁻¹ (A₁₃₀₀, µmol CO₂ m⁻² s⁻¹); (B) daytime respiration rate (R_d, µmol CO₂ m⁻² s⁻¹); (C) leaf photosynthetic nitrogen (N_ph, mmol N m⁻²); (D) maximum carboxylation rate (V_cmax, µmol CO₂ m⁻² s⁻¹); (E) maximum electron transport rate (J_max, µmol e⁻ m⁻² s⁻¹); (F) chlorophyll (Chl, mmol Chl m⁻²); (G) partitioning fraction of the carboxylation pool (p_V); (H) partitioning fraction of the electron transport pool (p_J); and (I) partitioning fraction of the light harvesting pool (p_C). The observed data were obtained in the greenhouse experiment. The dotted grey lines are one-to-one lines. Root mean squared deviation (RMSD) and accuracy of the predictions are shown (see Materials and methods).
