Carbon influx and outflux and organic carbon compound accumulation in leaves. Measurements were taken at control conditions (red) and after 7 days of cold treatment (blue), at the beginning of day (BOD) and at the end of day (EOD), using infrared gas analysis and enzyme assays.²⁴ The s.e.m. of the 3–4 replicates for each measurement is shown as error bars. The above data (excluding carbon outflux) were converted to \(\frac{{mmol}}{{gFW \cdot Day}}\) and used to constrain the Arnold model as outlined in the method. Significant differences between measurements across the two temperature conditions are indicated by an asterisk
