Does Getting Old Change Juvenile Tendencies? Maps Show Wood Variability in Mature Longleaf Pine

Snapshot: Juvenile wood in pines is usually shown as a central core of wood, varying little by diameter or cambial age, nested within mature wood tapering to the upper portion of the stem. The present study addresses the degree to which different representations of juvenile wood are applicable to a sampling of 70-yr-old longleaf pine trees.
Summary:

Established illustrations of juvenile wood in pines depict a central core of wood, varying little by diameter or cambial age, to be nested within mature wood tapering to the upper portion of the stem. The present study addresses the degree to which different representations of juvenile wood are applicable to a sampling of 70-yr-old longleaf pine trees. Wood property maps were derived from X-ray densitometry data gathered from tree disks taken at every 61 centimeters along each tree bole. Altogether, the wood property maps and data comparisons were consistent with an alternative juvenile wood illustration proposing that all the wood at the base of the tree, comprised of juvenile corewood and juvenile outerwood, are different from the majority of the tree wood upward from a one-quarter relative height.
