Présentation
I'm mainly involved in research on coarse root architecture of trees, with Pinus pinaster in sandy spodosols as model tree, studying variability as a function of genetic, environment and sylviculture. More specifically, we assess the role of roots in anchorage and acclimation to a prevailing wind. We consider that root systems are composed of several root types and develop analysis methods according to that.
