RACiR: the rapid A/Ci response;Isat : saturating light intensity (μmol m-2 s-1);VPDleaf : leaf to air vapor pressure deficit (kPa); Tleaf : leaf temperature (°C); FS : fan speed (rpm); FR : flow rate (μmol s-1);ΔP : chamber overpressure (kPa); Rate: rate of RACiR (μmol CO2 mol-1 min-1); Range: range of RACiR (μmol CO2mol-1).
Table 2. Modelled net daily carbon (C) gain under scenarios of diurnally changing, peak, average, or minimum Vcmax andmax , Percentage changes are expressed as change relative to the diurnal scenario. Bold values indicate cases where diurnal changes in photosynthetic capacity (bothVcmax and Jmax ) were significant.
