ABSTRACT:
A method is provided for reliably determining anatomical properties of a tree having a plurality of growth rings spaced from each other in a radial direction. The method involves preparing a sample from a tree to be analyzed, and preparing an image of the sample at a resolution sufficient to analyze at least one of the earlywood and latewood portions of one or more rings. The image is used to determine at least one anatomical property of the sample based on the image, the anatomical property being selected from the group consisting of sample density, tracheid wall thickness, and tracheid exterior dimension.
