Abstract

Extraction of polyphenols from the heartwood of loblolly pine, Fraser fir, and red spruce, followed by pectinase and cellulase treatments, resulted in the removal of chemical constituents and the creation of openings in the torus of bordered-pit membranes. The results suggest that during heartwood formation polyphenols rather than lignin are produced and deposited within the torus.
