Download or read book Four year Performance of Populus Deltoides Bartr and Some of Its Hybrids in Northwestern Ontario written by R. E. Farmer and published by Sault Ste Marie : Canada-Ontario Northern Ontario Development Agreement, Forestry. This book was released on 1994 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cold-hardy, disease resistant poplars that can outperform aspen for volume growth have the potential to broaden the variety of planting stock available to boreal forest managers. Moving selected eastern cottonwood from the north-central edge of its range to appropriate boreal sites and hybridizing these adapted selections with selected balsam poplar might offer further opportunity for simultaneously increasing hardiness and growth. Five clones 3uitable for pilot-scale use at latitudes of up to 49 degrees north in Ontario were identified via tests. This study evaluates the hardiness, disease susceptibility, and juvenile growth of 76 clones selected for their potential in the north. It also examines relationships between early morphological growth and growth characteristics that might be useful in early selection.

Download or read book Site quality Evaluation Site quality Maintenance and Site specific Management for Forest Land in Northwest Ontario written by Willard H. Carmean and published by Thunder Bay : Ontario Ministry of Natural Resources, Northwest Science and Technology. This book was released on 1996 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual is directed toward the evaluation and classification of forest land in north-west Ontario for timber production, with the primary objective of providing tools for a quantitative evaluation of the capability of forest land to produce tree growth. The first few chapters describe methods for estimating forest site quality, including direct methods based on measuring site index from standing trees and indirect methods based on soil and topographic features. The manual also provides a complementary framework showing relationships between site quality, forest-landscape classification, and growth and yield. This framework accommodates other land values that are in addition to timber production. A final chapter suggests how application of this integrated framework can produce a diversified forest landscape having a spectrum of management intensities, a variety of site-specific silvicultural practices, and a variety of forest land values and uses.

Book excerpt: Poplars and willows form an important component of forestry and agricultural systems, providing a wide range of wood and non-wood products. This book synthesizes research on poplars and willows, providing a practical worldwide overview and guide to their basic characteristics, cultivation and use, issues, problems and trends. Prominence is given to environmental benefits and the importance of poplar and willow cultivation in meeting the needs of people and communities, sustainable livelihoods, land use and development.

Download or read book Genetics and Genomics of Populus written by Stefan Jansson and published by Springer. This book was released on 2010-03-02 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetics and Genomics of Populus provides an indepth description of the genetic and genomic tools and approaches for Populus, examines the biology that has been elucidated using genomics, and looks to the future of this unique model plant. This volume is designed to serve both experienced Populus researchers and newcomers to the field. Contributors to the volume are a blend of researchers, some who have spent most of their research career on Populus and others that have moved to Populus from other model systems. Research on Populus forms a useful complement to research on Arabidopsis. In fact, many plant species found in nature are – in terms of the life history and genetics – more similar to Populus than to Arabidopsis. Thus, the genetic and genomic strategies and tools developed by the Populus community, and showcased in this volume, will hopefully provide inspiration for researchers working in other, less well developed, systems.

Download or read book Biology of Populus and Its Implications for Management and Conservation written by National Research Council Canada and published by NRC Research Press. This book was released on 1996 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Poplar is increasingly recognized as an excellent model tree for the study of tree growth and its underlying physiology and genetics. By studying trees of the genus Populus (poplars, cottonwoods, aspens), which in their native ecosystems play a major role in the re-colonization of sites after disturbances, new insights have been gained into plantation culture and the development of improved cultivars. Of the 20 chapters in this publication, editored by an international group of researchers, one section deals with systematics, genetics, genetic manipulation and biotic interactions of Populus, while the other deals with stress response and the physiology of growth and productivity" --

Available in PDF, EPUB and Kindle. Book excerpt: The burgeoning demand on the world food supply, coupled with concern over the use of chemical fertilizers, has led to an accelerated interest in the practice of precision agriculture. This practice involves the careful control and monitoring of plant nutrition to maximize the rate of growth and yield of crops, as well as their nutritional value.
