Abstract
AN important change which occurs in the wood of most trees as they grow older is the transformation of sapwood into heartwood. This change is associated with the death of the ray and vertical parenchyma cells, and definite modifications to the anatomy of both softwoods and hardwoods1. As a result, heartwood is more difficult to season, is less readily penetrated by preservatives and pulping liquors, and resinous extractives are troublesome.
