Partial cutting is known to enhance the growth of residual stems. However, a significant radial increase can lead to a lesser wood quality in regard of anatomy and density parameters. Our research aims to evaluate black spruce growth and wood quality within various partial cutting treatments in Quebec. We evaluated the annual yield and the wood quality by examining tree-ring density and anatomical features such as tracheid length, radial diameter and cell wall thickness. Results revealed a general increase of radial growth after partial cutting. A significant increase altered the anatomical properties as expressed by a decrease in cell wall thickness. Latewood proportion is also negatively proportional to tree-ring width. When both observations are combined, it impacts the wood density which can modify the mechanical properties. The intensity of partial cutting determines the magnitude of changes observed in wood growth and quality.
