Heartwood is the central, dense, and usually darker part of a tree trunk that no longer conducts water and nutrients, serving primarily to provide strength and structure to the tree. It is formed as a result of the tree's natural growth process, where new layers of wood are added each year. As the tree ages, the center of the trunk becomes filled with heartwood, gradually replacing the lighter, younger wood known as sapwood.
The distinctive coloration of heartwood is due to the accumulation of various chemical substances, such as resins, tannins, and pigments, which often impart a darker hue and may provide protection against decay and insect infestation. Notably, heartwood is generally more resistant to rot compared to the outer, living parts of the tree.
Due to its durability and strength, heartwood is valued for various purposes. It is commonly used in the construction industry for timber framing, furniture making, and flooring due to its appealing aesthetics and structural stability. Additionally, its resistance to decay makes it desirable for outdoor applications, such as decking and fencing.
In summary, heartwood is the inner, matured part of a tree trunk that is denser, darker, and more durable than the younger sapwood. Its formation provides strength and support to the tree while offering valuable properties for human use, including its resistance to decay and attractive appearance.
