In northern Vermont test plantation balsam fir provenances varied considerably in growth rate, specific gravity and tracheid length. In general, trees grown from seed collected in the eastern and central portions of the balsam fir range were faster growing, had lower specific gravities and longer tracheids than those grown from seed collected in the western port of the range. Mean provenance specific gravity and tracked length were strongly correlated with growth rate, however, significant provenance differences in specific gravity and tracheid length existed after adjusting for growth rate.
