In addition to genetic control, responses to environmental stimuli affect the success of rooting. Our objectives were to: 1) assess the variation in rooting ability among 21 Populus clones grown under varying soil temperatures and amounts of precipitation and 2) identify combinations of soil temperature and precipitation that promote rooting. The clones belonged to five genomic groups ([P. trichocarpa Torr. & Gray x P. deltoides Bartr. ex Marsh] x P. deltoides 'BC'; P. deltoides 'D'; P. deltoides x P. maximowiczii A. Henry 'DM'; P. deltoides x P. nigra L. 'DN'; P. nigra x maximowiczii 'NM').
