Root Chemistry of Mature Douglas-fir Differs by Habitat Type in the Inland Northwest Item Info

This paper describes root biochemical characteristics of naturally regenerated Douglas-fir trees growing on a wide variety of sites in the inland Northwest. Roots of trees growing on dry, warm Douglas-fir habitat series had significantly greater concentrations of sugar and tannins, higher tannin/suagar ratios, and significantly lower phenolic concentrations and phenolic/sugar ratios than the roots of Douglas-fir trees growing on grand fir habitat series or western red cedar habitat series. Possible links between Douglas-fir root biochemical characteristics and susceptibility to root disease, particularly Armillaria, and tree resistance to drought are discussed.
