Abstract
The basic properties of compression wood (CW), lateral wood (LW), and opposite wood (OW) in Sumatran pine and Agathis woods were evaluated according to the Korean Standard. CW showed the highest green and oven-dry density, longitudinal shrinkage, shear and compressive strengths but had the smallest green moisture content (GMC) and radial and tangential shrinkages. LW and OW showed a similarity in the GMC, radial, tangential and volumetric shrinkages, and shear strength, while LW exhibited a higher longitudinal shrinkage and slightly lower compressive strength than OW.
