  •  POSITION AND EDUCATION

2001 : Senior scientist (CR1), Plantes et Systèmes de culture Horticoles, INRA Avignon

1998-2001 Researcher (CR2), Plantes et Systèmes de culture Horticoles, INRA Avignon

1998 : PhD thesis in Agronomical Sciences – Modelling water uptake by root architecture under non-uniform water availabilities. Study on Peach (Prunus persica L. Batsch) in orchard.

  •  MAIN RESEARCH INTERESTS

 I am presently working on resources acquisition and transfer within a complex plant architecture. The resources transfer is modelled using the Munch flow hypothesis through architecture, linking water and carbohydrate flow through the xylem and phloem network. Processes such as resources acquisition (water and minerals uptake, carbon assimilation) and organs growth are dependant of exogenous availability (soil water content, radiation …) and local endogenous availability. The resources availabilities are expressed through the water potential and the carbohydrate concentration. 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.

 Key word: architecture, transfer, modelling, water, irrigation, carbohydrate
