Results of one-way ANOVA testing differences between control and all treatments in maximum electron transport rate (ETR_max, μmol e⁻m^–2 s–1), initial slope of the RLC (α) and saturation irradiance (<i>E</i>_k, μmol_photons m^–2 s^–1)_, productivity (P, gCO₂ gDW^–1), and P/R ratios for the whole plant (P/R_plant), photosynthetic tissue (P/R_ps), and non-photosynthetic tissue (P/R_nps).

Post hoc analyses are performed using the Student–Newman–Keuls method. Significant values (p < 0.05) are shown in bold.
