Résumé
Linking tree architectural development and carbon partitioning during a growing season has been identified as a weak point in functional-structural plant models . In the LPEACH model , carbon partitioning was used to drive organ growth, but the organs and shoot types were not accurately distributed within the tree. Our goal was to propose a solution for linking statistically-based models of architectural development with a physiologicallybased model of carbohydrate partitioning in peach trees. The approach was to integrate Markovian models representing the tree’s topology, that is, the connectivity of the tree’s entities into the L-PEACH model.
