Résumé
In the past, numerous techniques have been used in the representation of plants. The Plant Modeling Unit of CIRAD developed an original method of plant growth simulation based on botanical notions of plant architecture. But in simulating metamorphosis, the notion of a reference axis which shows all the stages of differenciation in a branch throughout its growth is needed. Also, if we consider the simultaneity of biological events which characterize a plant's functioning, we can study the environmental (nutrition and precipitation needs) and spatial (crowding, light influence) interactions. The reference axis is structured like a finite automaton and the discrete events simulation (scheduler) is used for the parallel simulation of the growth. (Résumé d'auteur)
