Modelled CO2 assimilation rate as a function of leaf temperature. The dotted line and its extension line show the enzyme-limited rate, and the dashed line and its extension line show the electron transport-limited rate. The CO2 assimilation rate was modelled at an irradiance of 2000 µmol m–2 s–1 and an intercellular CO2, Ci, of 150 µbar. Other parameters are as given in Table 1.
