It is widely recognized that spiral grain in trees severely reduces the value of sawn timber through warping and loss of strength, and that it also causes problems for other wood uses as diverse as transmission poles or plywood. Yet, paradoxically, there are highly valued grain patterns including wavy and interlocked grain, whose origins in the cambium invite direct comparison with those of spiral grain, so that many authorities believe them to be related phenomena. In recent years this concept has prompted extensive research into the anatomy, genetics, and physiology of all such grain patterns in wood. As a result it has become apparent that tree cambia provide excellent systems through which to study the origins of stem polarity and the complex processes of morphogenetic control in plants. Beside these and other pressing topics for research, 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.

Since the Scots pine species is most important in Eurasia, it was considered necessary to involve authors from as many countries as was possible including Eastern Europe and U.S.S.R. During the 18th IUFRO World Congress in Ljubljana, Yugoslavia, in September 1986, details were worked out for the contents of this book. This book is a truly international effort, prepared in the traditional IUFRO spirit of selfless co-operation. In all, 24 authors from 9 countries are involved. Each chapter was reviewed by two editors from two different countries.
