Présentation
I am presently working on resources acquisition and transfer within a complex plant architecture. The resources transfer through architecture is modelled, linking water and carbohydrate flow through the xylem and phloem network. These endogenous availabilities are resulting from the resources transfer in the architecture, the architecture (topology, geometry and transfer properties) connecting organs acting as sources and sink. Processes such as resources acquisition (water and minerals uptake, carbon assimilation) and organs growth are dependent of exogenous availability (soil water content, radiation …) and local endogenous availability (water potential, carbohydrate concentration …). The fruit growth and its quality is especially studied in response to various environmental conditions (temperature, radiation, water deficit) and to agricultural practices (irrigation, thinning, pruning) in order to better understand the link between the resource availabilities and the organs growth and composition.
