Figure 4.

Electron transport and fluorescence parameters of the leaves described in Figure 3. Parameters are φ_CO2,max (calculated as the initial slope of the photosynthetic carbon assimilation response to light; A), J_sat (B), φ_PSII,max,l (C), qP (D), and / at 2,000 μmol m⁻² s⁻¹ (E). All parameters were calculated from fluorescence measurements of electron transport rates in increasing light. Data presented as in Figure 3.
