註釋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.
