This book was released on 2013-11-27 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the beginning of agricultural production, there has been a continuous effort to grow more and better quality food to feed ever increasing popula tions. Both improved cultural practices and improved crop plants have alIowed us to divert more human resources to non-agricultural activities while still increasing agricultural production. Malthusian population predictions continue to alarm agricultural researchers, especially plant breeders, to seek new technologies that will continue to allow us to produce more and better food by fewer people on less land. Both improvement of existing cultivars and development of new high-yielding cultivars are common goals for breeders of alI crops. In vitro haploid production is among the new technologies that show great promise toward the goal of increasing crop yields by making similar germplasm available for many crops that was used to implement one of the greatest plant breeding success stories of this century, i. e. , the development of hybrid maize by crosses of inbred lines. One of the main applications of anther culture has been to produce diploid homozygous pure lines in a single generation, thus saving many generations of backcrossing to reach homozygosity by traditional means or in crops where self-pollination is not possible. Because doubled haploids are equivalent to inbred lines, their value has been appreciated by plant breeders for decades. The search for natural haploids and methods to induce them has been ongoing since the beginning of the 20th century.
Download or read book Genetic Manipulation of Woody Plants written by James W. Hanover and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Volume contains the papers presented by twenty-eight invited speakers at the symposium entitled, "Genetic Manipulation of Woody Plants," held at Michigan State University, East Lansing, Michigan, from June 21-25, 1987. Also included are abstracts of contributed poster papers presented during the meeting. That the molecular biology of woody plants is a rapidly expanding field is attested to by the large attendance and high level of enthusiasm generated at the conference. Leading scientists from throughout the world discussed challenging problems and presented new insights into the devel opment of in vitro culture systems, techniques for DNA analysis and manipulation, gene vector systems, and experimental systems that will lead to a clearer understanding of gene expression and regulation for woody plant species. The presence at the conference of both invited speakers and other scientists who work with nonwoody plant species also added depth to the discussions and applicability of the information presented at the conference. The editors want to commend the speakers for their well-organized and informative talks, and feel particularly indebted to the late Dr. Alexander Hollaender and others on the planning committee who assist ed in the selection of the invited speakers. The committee consisted of David Burger (University of California, Davis), Don J. Durzan (University of California, Davis) , Bruce Haissig (U. S. Department of Agriculture Forest Service), Stanley Krugman (U. S. Department of Agriculture Forest Service) , Ralph Mott (North Carolina State University), Otto Schwarz (Univer.sity of Tennessee, Knoxville), and Roger Timmis (Weyerhaeuser Company).
Download or read book Shedding of Plants Parts written by T.T. Kozlowski and published by Elsevier. This book was released on 2012-12-02 with total page 573 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shedding of Plant Parts focuses on the anatomical, physiological, and ecological features of shedding of vegetative and reproductive parts of plants. This book encompasses both natural and induced shedding. Organized into 12 chapters, this book first outlines the extent of shedding of plant cells, tissues, and organs and summarizes the biological and economic implications of such shedding. Separate chapters follow that discuss anatomical and histochemical changes in leaf abscission; the physiological ecology and internal regulation of abscission; and the shedding of shoots, branches, bark, roots, pollen, seeds, and reproductive structures of forest trees. This book also explains the anatomical changes in abscission of reproductive structures, chemical thinning of flowers and fruits, and chemical control of fruit abscission. This book will be valuable to plant anatomists, pathologists, and physiologists, and to agronomists, arborists, biochemists, ecologists, entomologists, foresters, horticulturists, landscape architects, meteorologists, and soil scientists.
