Abstract : The carbon status plays a key-role in flowering and fruiting of mango trees while influxes of carbohydrates seem to influence fruit size and taste. A model of carbon gain, losses and repartition between branch parts for mango is proposed. Photosynthesis represents the starting point of the modelling approach. The first step consisted of using 3D digitising to establish the relationship between the amount of leaf nitrogen per unit leaf area, N. and the gap fraction. The second step established the relationship between N. and the parameters of photosynthetic capacity derived from response curves of net photosynthesis to the intercellular CO2 concentration (A-Ci curves). Results are presented about this model. Its capacity for simulating leaf photosynthesis is also discussed. (Résumé d'auteur)
