Description: The inadvertent removal and/or damage of buds during processing and planting of hardwood poplar (Populus spp.) cuttings are a concern because of their potential impact on shoot and root development during establishment. The objective of the current study was to test for differences in shoot dry mass, root dry mass, number of roots, length of the longest root, and callus dry mass among ten poplar clones subjected to three pre-planting bud removal intensities (0%, 50%, 100%). The ten clones and their genomic groups were: DM115 (P. deltoides Bartr. ex Marsh x P. maximowiczii A. Henry); DN34, I45-51 (P. deltoides x P. nigra L.); NC13446, NC13563, NC13649, NC13685, NC13747 [(P. trichocarpa Torr. & Gray x P. deltoides) x P. deltoides]; and NM2, NM6 (P. nigra x P. maximowiczii).
Keywords: adventitious rooting, hybrid poplar, preplanting treatment, vegetative propagation, Populus deltoides, P. nigra, P. maximowiczii, P. trichocarpa
