Warpage of Studs from Young Growth Ponderosa Pine from Northern New Mexico

摘要

Lumber grade recovery and warp of studs from young ponderosa pine trees are affected by tree diameter, but not by a difference in site index from 55 to 100 or log position in the tree. Trees 9 inches d.b.h. yielded lower grade studs with more warp than 10- through 14-inch d.b.h. trees etc. (same as on quarterly list).
