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 andJmax , 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.
