Afforestation and stand age affected soil respiration and net ecosystem productivity in hybrid poplar plantations in central Alberta, Canada
DownloadFall 2010
Afforestation and stand development can significantly affect soil respiration and net ecosystem productivity (NEP). I studied 1) the effects of afforestation on NEP by comparing cropland previously planted to barley (on a barley-barley-alfalfa-alfalfa-alfalfa rotation) and that converted to a...

Assessing the Potential for Hybrid Vigour Within a Species: Disparate Population Breeding of Balsam Poplar
DownloadFall 2021
When two or more species are crossed to produce hybrid progeny, some of them can be expected to yield a growth performance far superior to that of either parent (i.e., hybrid vigour/heterosis). To date, there have been few attempts to examine whether hybrid vigour can be achieved by crossing...

In this study, growth of seven hybrid poplar clones and one pure poplar clone was investigated in relation to leaf, shoot, and root physiology under field conditions. Clones included: Walker (24 - P. deltoides x P. xpetrowskyana), Assiniboine (25 - open pollinated Walker cv. Assiniboine),...
