Example application of the plantecophys package to A-C_i curves and spot gas exchange measurements on <i>Eucalyptus delegatensis</i>.

<p>(A) Fitted A-C_i curves with one curve highlighted (B) Estimates of J_max plotted against V_cmax, obtained from the fitted curves in panel (A). Solid line is a regression line (J_max = 107.71 + 0.7 V_cmax, R² = 0.36) with a 95% confidence interval for the mean. (C) Modelled (with the model of Medlyn et al. 2011) versus measured g_s (p < 0.0001, R² = 0.69). Measurements included a wide range of environmental conditions (PAR, T_leaf, D). In this example, only g₁ was fit (estimate = 3.31, 95% CI = 3.15–3.47). (D) The predicted response of ITE (A_n / E) as a function of D from the fitted model in panel (C) (solid line), and the measurements from panel (C) when PAR > 1000.
