A simple process-based xylem growth model for describing wood microdensitometric profiles
A mechanistic model of xylem production based on physiological and anatomical assumptions is proposed. It focuses on tracheids and on the main phases of cell development : cell division enlargement and wall thickening. For each phase, the most limiting environmental factors are assessed and their effect is modeled with a weekly time step. Combined with simple process-based stand growth and yield models, which take the mean monthly climatic data into account, the xylem production model provides simulations of infra-annual density profiles along stem radius. Simulations are performed for two sites in Northeastern France, using past climatic data. The outputs are qualitatively discussed and visually compared with the observed microdensitometric profiles of #Pinus sylvestris# and #Picea abies# in these two sites. These models provide a basis for integrating timber quality features into process-based models. They also point to new sources of data that could be used to validate process-based models, and suggest some biological assumptions to understand the infra-annual variability of wood basic density.
