Excerpt from Compression Wood Formation and Other Characteristics of Plantation-Grown Pinus Caribaea
Compression wood was found in all stems and the amount present did not vary with height, but was influenced by an interaction of tree lean, growth rate, and slope of terrain. Orientation of compression wood appeared to have been influenced by a combined effect of lean, aspect of slope, and prevailing winds. Several levels of compression wood did not affect specific gravity, modulus of rupture, or work to maximum load in beam tests. Compression wood did reduce modulus of elasticity considerably. Longitudinal shrinkage increased with increasing amounts of compression wood; tangential, radial, and volumetric shrinkages decreased. Boards from these trees were kiln dried without seasoning degrade and were easy to machine even though high volumes of compression wood were present.
