Abstract

Improving carbon allocation in process based model is a challenging issue. A process model was prescribed using an extensive data set of growth and carbon fluxes (11 years) at the stand scale in order to draw new carbon allocation scheme in Q. ilex. Our results suggest that a part of summer photosynthesis is used for the renewal of fine roots.
