Résumé

Few studies have sought to understand the growth characteristics of tree species in order to explain the observed patterns of succession. This study seeks to determine the successional status of hardwood species in a secondary succession, to analyze their productivity and to examine the existing relationships between these two aspects. The age, production and biomass of 3273 stems were estimated in 34 stands distributed along a stand age gradient in south-western Quebec. The successional status of a species was determined by comparing its abundance with stand age in a contingency table. Linear regressions of the logarithm of the age of trees with the logarithm of the aerial biomass (log [B]), the logarithm of the net primary production (log[NPP]) and the relative biomass increment (NNP/B) were established for each species. An analysis of covariance allowed the separation of statistically different species regression curves. Sugar maple (Acer saccharum Marsh.), American beech (Fagus grandifolia Ehrh.) and eastern hemlock (Tsuga canadensis [L.] Carr.) are indicator species of old stands; bitternut hickory (Carya cordiformis [Wang.#K.##Koch#
