Аннотация: Spiral grain in trees severely reduces the value of sawn timber through warping and loss of strength, and it also causes problems for other wood uses as diverse as transmission poles or plywood. In recent years extensive research into the anatomy, genetics, and physiology of all such grain patterns has shown that tree cambia provide excellent systems for the study of stem polarity and the complex processes of morphogenetic control in plants, the book examines methods of measuring grain deviations, and considers their influence on wood properties, on the economics of timber production, and on wood manufacturing
