Overview

Until recently, the quality of juvenile wood and the resulting effect on the final product when used were ignored or not well known. However, due to the increased amount of juvenile wood, this knowledge has become essential. The forest industry needs to know the yields, qualities, and product characteristics of juvenile wood if major problems concerning product acceptability are to be avoided. This book documents the properties of juvenile wood with its effects on pulping and solid wood products and explores methods to reduce or change the characteristics of juvenile wood. Also included is an in-depth discussion of the potential use of juvenile wood, with examples from ongoing operations as well as from current research.
