Download or read book Geographic Variation in Forest Trees written by Maria Morgenstern and published by UBC Press. This book was released on 2011-11-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geographic Variation in Forest Trees is the first book to examine this subject from a world-wide perspective. The author discusses population genetic theory and genetic systems of native North American tree species as they interact with environments in the major climatic regions in the world. He then demonstrates how this knowledge is used to guide seed zoning and seed transfer in silviculture, basing much of his discussion on models developed in Scandinavia and North America. In the final chapter, the author addresses the issue of genetic conservation -- a subject of great concern in the face of accelerated forest destruction, industrial pollution, and climatic change. This comprehensive, well-researched book makes a significant contribution to the knowledge of one of our most important renewable natural resources.

Parker and published by Sault Ste. Marie, Ont. : Great Lakes Forestry Centre. This book was released on 1996 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a study conducted to obtain a better understanding of the pattern of adaptive variation of jack pine that would improve existing seed transfer guidelines. A short-term provenance test was conducted for 102 seed sources grown in common environments at a greenhouse for one season and at three field trials for two growing seasons. In the study, 32 biological variables were determined for each seed source, including seedling heights, needle flushing dates, timing of shoot elongation, and relative freezing damage. Multiple regressions were run for each variable against 12 climatic variables interpolated for each of the seed sources using a geographic information system (GIS). Principal components analysis summarized the main components of variation. Regression equations were used to model patterns of adaptive variation, and these patterns were graphically reproduced as contour maps using GIS. A series of focal point seed zone maps were then produced by GIS intersection of the regression-based contour maps. Based on these maps, a summary of the pattern of adaptive variation in jack pine was used to produce a recommendation for breeding zone boundaries.

Download or read book Wood Variation written by Bruce J. Zobel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is the usual end product of a forestry operation. Because of its importance, numerous studies have been made relative to wood prop erties, the causes of wood variation, and how best to develop wood for desired products. There is voluminous literature related to these subjects, but it is neither well known nor appreciated by foresters because the publications are often not available or are not well understood by the forester or by those who use the wood. Frequently, the literature is confusing and contradictory, making it difficult for the nonspecialist to use what information is available. In order to produce and use wood efficiently, the variation pat terns within trees, among trees within species, and among species must be understood. This also requires some knowledge of the causes of variation and the effects of different wood properties upon utiliza tion. The information about variation patterns, their causes, and con trol and effect upon the product must be known by the tree grower, the tree breeder, and the tree harvester as well as by those who ultimately convert wood into a final, salable product.
