Abstract

Rooting of dormant unrooted cuttings is crucial to the commercial deployment of intensively cultured poplar (Populus spp.) plantations because it is the first biological prerequisite to stand establishment. Rooting can be genetically controlled and subject to selection. Thus, our objective was to test for differences in rooting ability among cuttings from three positions on cutting orchard plants of five genomic groups ([Bartr. ex Marsh x P. trichocarpa Torr. & Gray P. deltoides] x P. deltoides 'BC', P. deltoides 'D;, P. deltoides H P. maximowiczii A. Henry 'DM', P. deltoides x P. nigra L. 'DN', P. nigra x P. maximowiczii 'NM').
