Simulated effects of daily light interception (I_Ld, mol photons m⁻² d⁻¹) and nitrogen supply level in the nutrient solution (N_S, mM) on maximum protein synthesis rate (S_max,X) in Eq. (7) using coefficients from Table 1, of (A) the carboxylation, (B) the electron transport and (C) the light harvesting pools. The colors denote the normalized maximum protein synthesis rate, which is S_max,X normalized by the potential maximum protein synthesis rate (S_mm,X) in Eq. (7). The data obtained in the growth chamber experiment were used for the parameterization. The arrows above and beside the figures indicate the corresponding average environmental conditions in the greenhouse experiment: high light (HL) 21.4 mol photons m⁻² d⁻¹; low light (LL) 8.5 mol photons m⁻² d⁻¹; high nitrogen (HN) 8.2 mM; low nitrogen (LN) 2.0 mM.
