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. | | 出版日期 | Book 1989 | | 关键词 | Silviculture; anatomy; genetics; growth; physiology; plants; tree; wood | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-642-73779-4 | | isbn_softcover | 978-3-642-73781-7 | | isbn_ebook | 978-3-642-73779-4Series ISSN 1431-8563 | | issn_series | 1431-8563 | | copyright | Springer-Verlag Berlin Heidelberg 1989 |
