This book was released on 2009 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much information is available for specific gravity and other properties of wood and bark, but it is widely scattered in the literature. This paper compiles information for estimation of biomass for 156 tree species found in North America for use in national forest inventory applications. We present specific gravities based on average green volume as well as 12 percent moisture content volume for calculation of oven-dry biomass. Additional information is included on bark thickness, bark voids, and bark percentages by species and green and dry weight of wood and bark. --

Download or read book Bark and Its Possible Uses written by John M. Harkin and published by . This book was released on 1971 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: What to do with bark is a major question facing the wood conversion industries. Optimum utilization of bark residues demands appreciation of the complexity of bark and the extreme variation in chemical and physical properties between barks of different wood species. This report discusses bark structure, past and present utilization, and methods of upgrading bark both physically and chemically for increased utilization. Pertinent literature citations and continuing bibliographic sources of information on bark are included. Appended directories indicate sources of technical assistance and utilization equipment.

Download or read book Genetics of Wood Production written by Bruce J. Zobel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past years, a great deal has been learned about variation in wood prop erties. Genetic control is a major source of variation in most wood properties. Wood is controlled genetically both directly in the developmental or internal pro cesses of wood formation and indirectly by the control of tree form and growth patterns. Emphasis in this book will be on the internal control of wood production by genetics although there will be two chapters dealing with the indirect genetic control of wood, which was covered in detail in the previous book by Zobel and van Buijtenen (1989). The literature on the genetics of wood is very variable, SO'lle quite superficial, on which little reliance can be placed, and some from well-designed and correctly executed research. When suitable, near the end of each chapter, there will be a summary with the authors' interpretation of the most important information in the chapter. The literature on the genetics of wood can be quite controversial. This is to be expected, since both the environment and its interaction with the genotype of the tree can have a major effect on wood properties, especially when trees of similar genotypes are grown under widely divergent conditions. Adding to the confusion, studies frequently have been designed and analyzed quite differently, resulting in conflicting assessments of results.
