Usefulness of vegetative propagation for the conservation of the genetic resources of elm trees

Abstract

Different vegetative propagation techniques have been successfully utilized for the ex situ conservation of the genetic resources of the three elm species native to Europe: Ulmus minor, U. glabra, U. laevis. Cuttings are a particularly valuable means to duplicate the material for which some kind of tolerance to Dutch Elm Disease is suspected and needs to be further assessed in susceptibility tests.
