ABSTRACT

The objective of this study was to investigate the influence of juvenile wood on the mechanical and physical properties of red alder. Tree growth in the first 10 to 20 years, usually referred to as juvenile wood, often influences wood quality by adversely affecting mechanical strength properties. Strength can be reduced up to 50 percent by the presence of juvenile wood. More knowledge of juvenile/mature wood properties will provide practical information for silviculturists and processors of red alder, leading to a more appropriate usage of this species. Six red alder ...
