F. Manes et al., Gas exchange measurements and an indirect estimate of primary production in a holm-oak ecosystem, FR ENV BULL, 7(1A-2A), 1998, pp. 71-78
An original and simple primary production model is presented. Annual trends
of the daily average values of net photosynthesis and leaf transpiration f
or helm oak are showed. Moreover, primary production data were obtained. To
validate the model, an evaluation between estimated results and field meas
urements was performed, obtaining a strong correspondence.
