Résumé : We built segmentation models to identify tree growth phases on the basis of retrospective measurement of annual shoot characteristics along the main stem. Growth phase duration distributions estimated within these models characterize the balance between ontogeny and environmental constraints in tree development at the population scale. These distributions have very contrasted characteristics in terms of shape and relative dispersion between ontogeny-driven and environment-driven tree development.
