Abstract
Total biomass, biomass production, component distribution, and water content of stems and branches were estimated in 24- and 25-year-old jack pine (Pinusbanksiana Lamb.) stands of four provenances planted at three Lake States locations. The initial spacing was 1.5 × 1.5 m (5 × 5 ft). Total biomass and mean annual biomass production (MAB) were negatively related to location latitude. The overall range of MAB was 2.6–5.8 t•ha−1•year−1 (about 1.2–2.6 tons•acre−1•year−1). The highest MAB was 58% higher than the maximum reported in the literature. Stems accounted for 64–75% and branches with needles for the rest of the aboveground biomass. Stem percentages decreased at the northernmost location. Stems of all harvested trees had a significantly higher water content (127–141% on a dry weight basis) than their branches with needles (100–115%). Water content was the lowest in late winter (March). The study showed that suitable seed source selection is a very important factor in increasing jack pine stand production in the Lake States.
