Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Genetics of Douglas-Fir Geneticists must be knowledgeable of the natural role of the genetic variability they dis card as well as that small portion of variability they now select to fulfill immediate needs. Thus, their general understanding of the species in nature is fully as important as a knowledge of its genetics.

Download or read book Douglas-Fir written by Denis P. Lavender and published by Oregon Forest Research Laboratory. This book was released on 2014-06-21 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Douglas-fir (Pseudotsuga menziesii) has a wide distribution in North America and is one of the tree species most widely distributed outside its natural range. The species has been introduced to Europe, New Zealand, South America, and elsewhere around the world. At present, Douglas-fir is an accepted and integral part of forest management in many countries because of its economic importance and its reputation as a genus that may be able to deal with climate change. This book provides an overview of research activities and findings that highlights unique aspects of Douglas-fir physiology, genetics, and other related issues. The authors have pulled together a tremendous amount of information, starting with the evolutionary history and distribution of the genus Pseudotsuga. They provide a detailed description of introductions of Douglas-fir to other countries, including information about initial plantings, provenance trials, and genetic tree improvement activities. In the next sections about life history, the authors bring to bear their long-time research and teaching experiences with detailed descriptions of flowering, seeds, root, and seedling physiology, followed by sections about mycorrhizae and insects, diseases, and other biotic factors. This book will stand the test of time as an invaluable collection and cornerstone of information. It is intended as a resource for everybody interested in understanding the opportunities and challenges of managing Douglas-fir in a variety of regions and settings. It provides information for historians and social scientists investigating forestry trends; researchers, educators, and managers who look for detailed information in areas such as genetics and regeneration practices; and all others interested in the beautiful trees we call Douglas-fir.

Download or read book Introduction to Forest Genetics written by Jonathan Wright and published by Elsevier. This book was released on 2012-12-02 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Forest Genetics examines some of the basic genetic concepts typically used in forestry and tree improvement studies, including Mendelian and population genetics. It also describes techniques that are generally useful in tree improvement work, including individual tree selection and breeding, provenance testing, species and racial hybridization, and introduction of exotics. Organized into 19 chapters, this volume begins with an overview of forest genetics and problems associated with forest genetics. It then discusses concepts from basic genetics, including chromosome structure and function; DNA and RNA; nongenetic inheritance; and genotype versus phenotype. Other chapters focus on inbreeding: complete elimination of homozygous recessive trees; mutation and migration; and controlled pollination and vegetative propagation. The book also covers the establishment and measurement of test plantations; general principles and methods of selective breeding; choice of breeding method and type of seed orchard; heritability and genetic gain; geographic variation in Scotch pine and American trees; species and racial hybridization; chromosome studies; and polyploidy and haploidy breeding. This book is a valuable resource for foresters, professional tree breeders, and those with or without previous training in genetics or forestry.

Download or read book Tree Breeding and Genetics in New Zealand written by C.J.A. Shelbourne and published by Springer. This book was released on 2019-08-09 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dothistroma pini changed New Zealand commercial forestry dramatically. Tree breeding became concentrated on a very few species and development of selection methods and breeding strategies changed in response to the new challenges. Tree-Breeding and Genetics in New Zealand provides a critical historical account of the work on provenance research and tree breeding, often with the wisdom of hindsight, and it tracks the development of breeding strategy, especially for P. radiata, Douglas-fir and the most important eucalypt species, E. regnans, E. fastigata and E. nitens. The book is a compendium of abstracts and summaries of all publications and reports on tree improvement in New Zealand since the early 1950s, with added critical comment by the author on much of the work. It is intended for other tree breeders internationally, for interested NZ foresters and for graduate students studying genetics and tree breeding.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Douglas-fir (Pseudotsuga menziesii) is a widely distributed, ecologically important, and commercially valuable tree species in North America. However, climate change is expected to adversely impact Douglas-fir trees, and assisted migration may become necessary to lessen the effects of climate change. Because drought stress is one of the projected effects of climate change in the western U.S., it is increasingly important to include drought adaptation traits in breeding programs and in reforestation decisions.In this study, I addressed the following objectives: (1) obtain baseline measurements and climate data to help in the analysis and interpretation of future measurements in the Drought Hardiness Study; (2) characterize the quantitative genetics of drought adaptation traits; and (3) determine whether drought adaptation traits are associated with the climatic origin of Douglas-fir seedlings. To achieve these objectives, data were collected from about 10,000 Douglas-fir seedlings from 429 families from western Oregon and Washington that were planted at two sites (Sprague and Lost Creek) in southern Oregon. Measured variables, which I refer to as drought adaptation traits, included height, second flushing, spring bud flush, damage (foliage, stems, and leaders), and survival. I will discuss the design and results of a study that help increase the understanding about the importance of climatic-driven genetic differences for drought adaptation traits in Douglas-fir. The results of this study will provide useful information for understanding drought, enhancing breeding programs, and potentially adjusting forest management to climate change impacts.

Download or read book Forest Tree Breeding in Europe written by Luc E Pâques and published by Springer Science & Business Media. This book was released on 2013-05-31 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest tree breeding has been ongoing for more than 70 years across Europe. It has successfully generated improved varieties for the major economical forest tree species. They are part of the present European forestry landscape and largely contribute to intensive wood production and other forest activities. In this book, we describe the state-of-art of breeding for the main forest tree species. We provide a comprehensive, unique and up-to-date overview of the major scientific results and breeding achievements gathered from the many programmes scattered across Europe. The book is divided into 10 chapters, each as a monograph corresponding to a species or group of species Abies spp., (Larix spp., Picea abies, Picea sitchensis, Pinus sylvestris, Pseudotsuga menziesii, and Mediterranean pines; Acer pseudoplatanus, Fraxinus excelsior, and Prunus avium). Each of them is written by a group of experts and focuses on the distribution and economical importance of the species; motivation for breeding and breeding objectives; intraspecific genetic variability, breeding populations and breeding strategy; forest reproductive material deployment including mass-propagation and, prospects and perspectives for joint research and breeding. The book is a unique and up-dated source of information for students, researchers and professionals interested in the genetics and domestication of forest tree species.
