Book excerpt: The purpose of our studies with sugar maple was to develop a method by which superior sugar producers could be vegetatively propagated and grown for use in studies designed to improve sugar yields. Because high sugar producers will ordinarily be selected from trees of tapping size, our studies were conducted on relatively large roadside sugar maples (fig. 1). Branches on a couple of young sugar maples less than 2 inches d.b.h. were also treated.

Available in PDF, EPUB and Kindle. Book excerpt: Because of the growing need for wood fiber in the pulp and paper industry there is an opportunity for sawmill operators to increase their income by converting hardwwood sawmill residues (slabs, edgings, and trim) to pulp chips. By selling wood chips and reducing residue-disposal costs, sawmills could improve their utilization of sawlogs. But to justify the installation of debarking and chipping machines, and to know what such machines could contribute to his business, the sawmill owner must have a thorough understanding of the costs involved in chip production. To help him in this we have made case studies of seven sawmills in southeastern Ohio, eastern Kentucky, and Tennessee, and have analyzed all the factos of cost involved in chip production.

Download or read book Improvement in Butt log Grade with Increase in Tree Size for Six Hardwood Species written by George R. Trimble (Jr.) and published by . This book was released on 1965 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2Work carried out by the Northeastern Forest Experiment Station in West Virginia in the past 12 years provides useful information about the relationships between tree d.b.h. and butt-log grade. The upper logs are not included in the relationships. Being smaller and containing more knots, these upper logs are generally of lower grade than the butt logs. Thus the average grade of all material in the sawlog portion of the tree is generally lower than the average grade of the butt log. In the West Virginia data, species differences in d.b.h.-grade relationship are readily apparent. This inherent tendency for species to have different proportions of the various grades in logs of the same size is a familiar phenomenon to grade-conscious foresters who work with hardwoods. The results in this paper provide a quantitative evaluation of this tendency for six of the local species.S3.

Available in PDF, EPUB and Kindle. Book excerpt: 'frees contribute a major part of fuel, fodder and fruit, and are an im of bioenergy. They are now needed in large numbers more portant source than ever before for afforestation and social forestry, so that fast-grow ing and multipurpose trees assume great importance. After extensive in discriminate deforestation and rapid depletion of genetic stocks, efforts are now being made to evolve methods for clonal mass propagation of improved and elite trees. Production of short-duration trees with a rapid turnover of biomass, and induction of genetic variability through in vitro manipulation for the production of novel fruit and forest trees, which are high-yielding and resistant to pests and diseases, and trees which display increased photosynthetic efficiency are in demand. These objectives are well within the realm of horticultural and forest biotech nology. Some of the recent advances, such as the regeneration of com plete trees from isolated protoplasts, somatic hybridization, and the Agrobacterium-mediated transformation in various tree species have opened new vistas for the genetic engineering of fruit and forest trees. This book is a continuation of the earlier volume Trees I, and presents 31 chapters on fruit, forest, nut and ornamental trees, such as avocado, pineapple, crabapple, quince, pistachio, walnut, hazelnut, date palm, oil palm, cacao, rubber, maple, sweet-gum, poplars, birches, Chinese tallow, willows, oaks, paper mulberry, rhododendrons, Scots pine, Calabrian pine, Douglas-fir, redwood, ginkgo, cycads and some flowering trees.
