sapwood

The Columbia Encyclopedia, 6th ed. | 2008 | Copyright

sapwood relatively thin, youngest, outer part of the woody stem of a tree, the part that conducts water and dissolved materials. In the cross section of a tree, the sapwood is recognizable by its texture and color; it is softer and lighter than the inner heartwood . As the tree grows in diameter, the innermost layers of sapwood become heartwood, and new sapwood is produced on the outside of the woody column. See wood .
