Poplar culture in North America : proceedings of the 21st Session of the International Poplar Commission

This book describes the status of culture and utilization of poplars in North America and documents succinctly recent scientific and technological advances. Gathering under one cover important source information about North American poplars for the benefit of poplar growers and scientists, the book provides perspectives on the current status and future prospects of all aspects of the poplar sector. The scope of the work includes all Populus species native to Canada and the United States, naturally-occurring hybrids and varieties, as well as cultivars in current regular use. This book is intended to gather under one cover important source information about North American poplars for the benefit of poplar growers and scientists. The scope of the work encompasses all Populus species native to Canada & the United States, including aspens, cottonwoods, naturally occurring hybrids & varieties, and cultivars in current regular use. The first part contains ten chapters that summarize practical knowledge on growing & using poplars. These chapters describe natural species, varieties, & provenances; poplar breeding techniques & strategies; the physiological ecology of poplars; the silviculture & ecology of natural stands and plantations; the use of poplars in urban plantings, windbreaks, and phytoremediation; poplar insects & diseases; and wood properties & utilization. The second part contains four chapters describing the characteristics of the principal poplar clones & cultivars used in North America. It includes discussions of clonal morphology, phenology, sensitivity to insects & pathogens, growth, site relations, wood properties, importance, and regional suitabilty. It also reviews breeding strategies that may be used for poplars in the 21st century Acknowledgements -- References -- Chapter 5.
