General Concepts of Juvenile Wood
As a tree grows, the wood produced varies both across the radius of the bole and along the height of the tree. Such within tree variation can be very large, especially in the conifers. When this variation is added to the inherent genetic differences in wood quality among trees, tremendous within species variation results. When one also considers the variation resulting from site differences and seed source used, it becomes very difficult to predict wood qualities. However, to ensure the best utilization of wood products, such variations must be considered. It is important to always remember that anything which affects the physiology and growth of a tree can affect its wood properties. Although the variation pattern of wood properties differs among species and with individual trees within species, it is present within trees, among trees, among families, among genera and among species.
