An overview of silvicultural influences on loblolly pine veneer-basedpanel properties
Loblolly pine (Pinus taeda L.) harvested from five silviculturally different stands was used to manufacture 13-ply laminated veneer lumber (LVL) and 3-ply plywood. LVL panels were assembled as either all A-grade or all C-grade veneer. Plywood panels were produced according to four different veneer grade layups (AAA, ACA, ACC, and CCC). Many significant differences in modulus of elasticity (MOE) and modulus of rupture (MOR) were found to exist between the stands for both panel products. MOR significantly varied according to stand for both LVL but not plywood, and MOE varied significantly according to stand for plywood but not LVL.
