Geographic Variation in Forest Trees


Book Description

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.




Genetics of Jack Pine


Book Description

Pinus banksiana. Reviews its characteristics including taxonomy, range and habitat, biogeography, reproduction, genetics and breeding, and effects of ionizing radiation.




Geographic Distribution of the Pines of the World


Book Description

The scope of this publication is limited to mappable information about where pines grow naturally at present. We have not tried to relate present distribution to the fossil record, nor have we tried to indicate the ecological and historical factors controlling species distribution. The elevations at which pines grow are mentioned only in the most general terms; this aspect of distribution is intimately related to latitude, topography, and other features of the local environment.
















Somatic Embryogenesis in Woody Plants


Book Description

The rapid progress made on somatic embryogenesis and its prospects for potential applications in improving woody plants prompted us to edit this book initially in three volumes, and now to add two more volumes. The editors were all convinced that such a treatise was needed and would be extremely useful to researchers and students. This Volume 4 has been divided into three sections and contains 23 chapters. Section A contains eleven chapters covering studies of embryo development and cell biology of white spruce, proliferative somatic embryogenesis in woody species, somatic embryo germination and desiccation tolerance in conifers, performance of conifer somatic seedlings, apoptosis during early somatic embryogenesis, water relation parameters in conifer embryos, image analysis of somatic embryos, somatic embryogenesis in woody legumes, cold storage and cryopreservation, and commercialization of plant somatic embryogenesis. Section B contains six chapters dealing with angiosperm woody plants, such as somatic embryogenesis in myrtaceous plants, Laurus nobilis, Simarouba glauca, Magnolia spp., Juglans cinera, and somatic embryogenesis and evaluation of variability in somatic seedlings of Quercus serrata by RAPD markers. The chapters contained in Section C are focused on somatic embryogenesis in gymnosperms, including Pinus patula, Encephalartos, Picea wilsonii, Pinus banksiana, hybrid firs, and Taxus. All the chapters have been peer-reviewed and revised accordingly to improve their quality.
