Pinus banksiana Lamb. seedlings from the eastern, central, and western part of the natural range of the species were grown under three photoperiods and three temperatures in controlled environment rooms, and in a greenhouse. An analysis of NPK and ash content verified the presence of differences due to the source of the seed, and illustrated the importance of environmental conditions during progeny evaluation. Certain environmental conditions masked genetic differences, while other conditions maximized them.
