Thinning serves as a means of regulating both growth and the qualities of wood. Thinned plantations yield larger and higher quality logs, which are characterized by superior wood quality. The influence of thinning on crown development and growth rate can impact wood quality. Thinning induces earlier activity of the cambium in thinned stands compared to unthinned ones, yet it leads to delayed production of latewood. Wood quality refers to wood's suitability for specific end uses. Many wood quality attributes are hereditary, and variations in quality among trees of the same species can be attributed to genetic distinctions. The standards for wood usage are outlined in terms of lumber grading. Key wood quality attributes encompass wood density, density variance, distribution of juvenile and mature wood, heartwood-to sapwood ratio, fiber length, fibril angle, compression wood, knots, and grain orientation.
