DescriptionJack pine (Pinus banksiana Lamb.) is widely used in Lake States reforestation because of its ability to make rapid early growth on relatively infertile sites. It is a major pulpwood producing species. Since the quality and yield of pulp are so strongly influenced by tracheid length and specific gravity, information on genetic variation in these characteristics would be useful in planning future jack pine tree improvement programs. This study was done to: 1) measure tracheid length and specific gravity variation by seed source in the juvenile wood of jack pine; and 2) develop a basis for comparing wood quality variation by seed source in young seedlings with that in mature trees.
