Example application of the plantecophys package to A-Ci curves and spot gas exchange measurements on Eucalyptus delegatensis.

(A) Fitted A-Ci curves with one curve highlighted (B) Estimates of Jmax plotted against Vcmax, obtained from the fitted curves in panel (A). Solid line is a regression line (Jmax = 107.71 + 0.7 Vcmax, R2 = 0.36) with a 95% confidence interval for the mean. (C) Modelled (with the model of Medlyn et al. 2011) versus measured gs (p 2 = 0.69). Measurements included a wide range of environmental conditions (PAR, Tleaf, D). In this example, only g1 was fit (estimate = 3.31, 95% CI = 3.15–3.47). (D) The predicted response of ITE (An / E) as a function of D from the fitted model in panel (C) (solid line), and the measurements from panel (C) when PAR > 1000.
