Abstract:
In the present work the vegetative propagation of Ulmus pumila L. by stem cuttings is studied in order todevelop clonal lines for short rotation coppicein central Spain. Plant material was obtained from selected trees that had been grown from seeds in a long-term short rotation plantation of U. pumila. Criteria of selection for mother plants were the quantity of sprouts and sproutsdiameter since these traits influence the quality of coppice biomass. A total of 20 clones weremultiplied in greenhouse heated beds with two types of substrates, perlite and sand,as well as in the field. Rooting and survival of the different clones was highly variable.In heated beds the bestresults were obtained using perlite as a rooting substrate.Survival of 14-21 mm diameter cuttingswas higher than for thinner cuttings. In direct field planting of cuttings,the cutting diameter and the survival seemed not to be correlatedexcept for diameters of less than7 mm, which clearly showed low survival. General conclusion of this work was that the vegetative propagation of U.pumila is more successful with thick cuttings.
