Wood Variation

the long version

Wood is a very variable substance with differences occurring among species and genera, among geographic sources within a species and among trees within a geographic source as well as within each individual tree. Tree-to-tree variability is especially large, with differences within a species often under strong genetic influence. This book concentrates on the causes of variation in wood, the effects of this variation and the possibility of obtaining control through (genetic) manipulation to produce more uniform and usable wood products.
