In a previous study by our group (Ripoll et al. (1993), C.R. Acad. Sci. Paris, 316, 1438-1445), it was observed that the value of the Na/Ca concentration ratio was much larger in the cells with differentiated secondary walls (e.g. fibres in flax plants, or xylem of woody dicotyledons) than it was in the other cells. In the present contribution we study the relative distributions of Na, Mg and Ca in the various cell types (meristem, phloem and xylem) of the cambial area of 1 to 2 years old branches of beech trees (Fagus sylvatica L.).
