Book Synopsis Utilization of Residual Forest Biomass by : Pentti Hakkila
Download or read book Utilization of Residual Forest Biomass written by Pentti Hakkila and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increase in the demand for wood results in improved recovery and less residual biomass in the forests. Paradoxically, interest in forest residue as a renewable source of raw material seems to be in a reverse ratio to its availability in a certain area. Finland and Sweden are probably more dependent on forestry and forest in dustries than any other developed countries in the world. A sufficiency of raw ma terial for integrated forest industries is vital for the national economy of both countries, and a great deal of attention is being paid to the long-term potential of unutilized biomass left behind in logging operations. Furthermore, since these countries possess no reserves of fossil fuels, and since their per-capita consump tion of primary energy is exceptionally high, they also consider unmerchantable forest biomass a realistic source of indigenous energy. A joint Nordic research project on harvesting and utilization of logging residue was carried out in 1969-1976 under the auspices of the Nordic Research Council on Forest Operations. This fruitful cooperation soon gave rise to related national projects in Sweden, Finland, Norway, and Denmark, stimulating further research and producing practical applications. Concurrently, particularly after the worldwide energy crisis in 1973, research on all aspects of utilization of forest bio mass mushroomed in the United States, Canada, and the Soviet Union. An ex plosive increase occurred in both the number and diversity of biomass studies.

Available in PDF, EPUB and Kindle. Book excerpt: Felix qui potuit rerum cognoscere causas. Pub/ius Vergilius Mara Forests have long been one of mankind's most important natural re sources and not the least because forests are, if properly managed, re newable. They serve us in many different ways, but above all in pro viding us with wood, one of the most remarkable and useful of all natural materials. Reaction wood, compression wood in gymnosperms and tension wood in the arboreal angiosperms, serves the function of making it possible for trees to perform movements. In the ancient Ginkgo and in the conifers, the ability to form compression wood is of vital importance to each and every tree. Compression wood plays a crucial role in the regulation of tree form in these gymnosperms, and their arborescent habit probably depends on their ability to develop this tissue. Few forest and plantation trees are devoid of compression wood in their stem, and all of them have it in their branches. Unfortu nately, what is necessary and beneficial for the tree in this case is harmful to mankind, for compression wood is a very serious defect in both sawtimber and pulpwood. It is now almost 20 years since the last complete survey of compres sion wood was published, namely Arthur H. Westing's excellent review of this subject. My major objective in writing the present book has been to bring together in one single work everything that is currently known about compression wood.

Book Synopsis Hydraulic Properties of Compression Wood in Branches and Reoriented Shoots of Douglas-fir (Psuedotsuga Menziesii) by : Rachel Spicer
Download or read book Hydraulic Properties of Compression Wood in Branches and Reoriented Shoots of Douglas-fir (Psuedotsuga Menziesii) written by Rachel Spicer and published by . This book was released on 1997 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Xylem anatomy is a strong determinant of water transport efficiency and is therefore an important component of the overall hydraulic strategy of any woody plant. However, in addition to its role in water transport, xylem also serves in mechanical support, and these two functions may represent conflicting design requirements. To further our understanding of how mechanical requirements might affect water transport in woody plants, this research evaluates the efficiency with which compression wood, which is specialized to function in mechanical support, conducts water. Using young Douglas-fir (Pseudotsuga menziesii) trees, two modes of compression wood formation are considered: normally-growing branches and branches that take over as leaders. Lower branch halves, which contained large amounts of compression wood, were significantly limited in their ability to conduct water relative to upper halves. This is likely a result of their anatomy, as lower halves were denser and had shorter tracheids with narrower cell lumens than upper halves. Compression wood samples from branches that had taken over as leaders were also limited in their ability to conduct water, relative to samples from the wood formed opposite and to the sides of compression wood. In addition, compression wood samples from branches that had taken over as leaders were less permeable than lower branch halves. Despite the poor transport efficiency of lower branch halves, the amount of compression wood visible on the end of each branch segment did not explain any significant variation in whole segment hydraulic properties. This lack of relationship between compression wood and whole segment properties suggests that branches may make up for the lost conductive capacity in some way. In branches that replaced a missing leader, there was no evidence that xylem formed elsewhere in the segment (i.e., "opposite wood") made up for the loss through a concomitant increase in permeability. Instead, branches that replaced leaders increased their transport efficiency relative to normal branches through an increase in conducting cross-sectional area. Given the reduced permeability of compression wood, future work should address how woody plants minimize or counteract the detrimental effects of this mechanically-specialized xylem to fulfill their water transport needs.

Book Synopsis The Biology of Reaction Wood by : Barry Gardiner
Download or read book The Biology of Reaction Wood written by Barry Gardiner and published by Springer Science & Business Media. This book was released on 2014-01-08 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a fundamental reference source on reaction wood for wood scientists and technologists, plant biologists, silviculturists, forest ecologists, and anyone involved in the growing of trees and the processing of wood. It brings together our current understanding of all aspects of reaction wood, and is the first book to discuss both compression wood and tension wood. Trees produce reaction wood to maintain the vertical orientation of their stems and the optimum angle of each branch. They achieve this by laying down fibre cell walls in which differences in physical and chemical structure from those of normal fibres are expressed as differential stresses across the stem or branch. This process, while of obvious value for the survival of the tree, causes serious problems for the utilisation of timber. Timber derived from trees containing significant amounts of reaction wood is subject to dimensional instability on drying, causing twisting, bending and splitting. It is also difficult to work as timber, and for the pulp and paper industry the cost of removing the increased amount of lignin in compression wood is substantial. This has both practical and economic consequences for industry. Understanding the factors controlling reaction wood formation and its effect on wood structure is therefore fundamental to our understanding of the adaptation of trees to their environment and to the sustainable use of wood. The topics covered include: -Morphology, anatomy and ultrastructure of reaction wood -Cell-wall polymers in reaction wood and their biosynthesis -Changes in tree proteomes during reaction wood formation -The biomechanical action and biological functions of reaction wood - Physical and mechanical properties of reaction wood from the scale of cell walls to planks -The detection and characterisation of compression wood -Effects of reaction wood on the performance of wood and wood-based products - Commercial implications of reaction wood and the influence of forest management on its formation
Book Synopsis The Supporting Roots of Trees and Woody Plants: Form, Function and Physiology by : A. Stokes
Download or read book The Supporting Roots of Trees and Woody Plants: Form, Function and Physiology written by A. Stokes and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication comprises the proceedings of the first International Conference devoted to the structural roots of trees and woody plants. 'The Supporting Roots - Structure and Function,' 20-24 July 1998, Bordeaux, France. The meeting was held under the auspices ofIUFRO WPS 2. 01. 13 'Root Physiology and Symbiosis,' and its aim was to bring together scientific researchers, foresters and arboriculturalists, to discuss current problems in structural root research and disseminate knowledge to an audience from a wide disciplinary background. For the first time in an international conference, emphasis was placed on presenting recent reseach in the field of tree anchorage mechanics and root biomechanics. The way in which tree stability can be affected by root system symmetry and architecture was addressed, as well as how movement during wind sway can influence the development and shape of woody roots. The role of different nursery and planting techniques was discussed, in relation to effects on root system form and development. Root response to different environmental stresses, including water, temperature, nutrient and mechanical stress was addressed in detail. The structure and function of woody roots was also considered at different levels, from coarse to fine roots, with several papers discussing the interaction between roots and the rhizosphere. One of the conference highlights was the presentation of new methods in root research, by a series of workshops held at LRBB-INRA, Pierroton, on the northern border of the Gascony forest.
