Abstract
Using apical or axillary bud explants sampled on adult trees during do rmancy in natural conditions, microcutting of Fraxinus excelsior L. wa s successfully obtained. During the multiplication phase both a length ening and a rejuvenation of sprouts were obtained. This phase was the focus point from which several morphogenetic pathways could be initiat ed, i.e. direct or delayed rooting of rejuvenated sprouts, resting per iod mimicking a dormant but reversible state. Following subculture cyc les, the multiplication coefficient increased or was maintained at its previous level.
