Large differences were found in the yield of monoterpenes from xylem, bark, and needles of blue spruce (Picea pungens Engelm.). Yields were greatest from bark samples and least from xylem. There were significant differences among trees in yield for all tissues. Yield of xylem and needle but not bark monoterpenes varied with position in the crown. Yields of total monoterpenes in xylem and needle samples were highly correlated with the proportion of resin canals in these tissues. Needle and bark extracts showed significant among-tree differences in the relative concentrations of most monoterpenes. Concentrations of most monoterpenes in needle and xylem extracts varied significantly with position in the crown, while few bark monoterpenes varied significantly. For. Sci. 33(4):1081-1088.
