Clonal propagation of ornamental forms of Ulmus L. and Acer L. in a dendrological park Sofiivka of the NAS of Ukraine

Abstract

Clonal propagation of ornamental forms of elm trees (Ulmus L.) and maple trees (Acer L.) by means of autumn cutting and bud grafting during winter, spring, late spring and early summer periods of vegetation was studied. Ornamental forms of Ulmus L. were found to take roots well in all terms of propagation. Bud grafting when trees burst into leaves is considered to be most successful for various species and ornamental forms of Acer L. (the end of March – April).
