| Abstract: | This study tested 6 drying shrinkages of white birch wood(%Betula platyphylla%) from plantations.The 6 drying shrinkages include tangential shrinkage, radial shrinkage, and volume shrinkage in oven and air dry conditions. Five birch provenances were selected as testing materials. Variance analysis indicates that we can select the good provenance for the drying shrinkages of white birch are very small, the variance is not great, and the dimension stability is good. |
