Table 1.
Statistics of fitting the model to photosynthetic data. The percentage of the error mean square accounted for by each of the three terms of the model is included. In all cases, the model was highly significant (P < 0.0001). The number of measurements (n) used in parameterizing the model for each temperature band is also shown.
