Morphological Variations in Jack Pine (Pinus Banksiana) Along its' Central to Northern Population Ranges
The analysis of six jack pine populations along a north-south transect through the MacKenzie River Valley in the Northwest Territories revealed no significant latitudinal trends in cone and seed morphometric measurements. In attempting to determine whether any variations may be environmentally induc...
