Normand Frédéric, Habib Robert, Chadoeuf Joël. 2002. A stochastic flowering model describing an asynchronically flowering set of trees. Annals of Botany, 90 (3) : 405-415.

Résumé : A general stochastic model is presented that simulates the time course of flowering of individual trees and populations, integrating the synchronization of flowering both between and within trees. Making some hypotheses, a simplified expression of the model, called the 'shoot' model, is proposed, in which the synchronization of flowering both between and within trees is characterized by specific parameters. Two derived models, the 'tree' model and the 'population' model, are presented. They neglect the asynchrony of flowering, respectively, within trees, and between and within trees. Models were fitted and tested using data on flowering of #Psidium cattleianum# observed at study sites at elevations of 200, 520 and 890 m in Réunion Island. The 'shoot' model fitted the data best and reproduced the strong irregularities in flowering shown by empirical data. The asynchrony of flowering in #P. cattleianum# was more pronounced within than between trees. Simulations showed that various flowering patterns can be reproduced by the 'shoot' model. The use of different levels of organization of the general model is discussed.
