Download or read book Plant Aging written by Roberto Rodríguez and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many, the terms aging, maturation and senescence are synonymous and used interchangeably, but they should not be. Whereas senescence represents an endogenously controlled degenerative programme leading to plant or organ death, genetiC aging encompasses a wide array of passive degenerative genetiC processes driven primarily by exogenous factors (Leopold, 1975). Aging is therefore considered a consequence of genetiC lesions that accumulate over time, but by themselves do not necessarily cause death. These lesions are probably made more severe by the increase in size and complexity in trees and their attendant physiology. Thus while the withering of flower petals following pollination can be considered senescence, the loss of viability of stored seeds more clearly represents aging (Norden, 1988). The very recent book "Senescence and Aging in Plants" does not discuss trees, the most dominant group of plants on the earth. Yet both angiospermic and gymnospermic trees also undergo the above phenomena but less is known about them. Do woody plants senesce or do they just age? What is phase change? Is this synonymous with maturation? While it is now becoming recognized that there is no programmed senescence in trees, senescence of their parts, even in gymnosperms (e. g. , needles of temperate conifers las t an average of 3. 5 years), is common; but aging is a readily acknowledged phenomenon. In theory, at least, in the absence of any programmed senescence trees should -live forever, but in practice they do not.

Download or read book Progress in Temperate Fruit Breeding written by H. Schmidt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the papers and posters presented at the Eucarpia Fruit Breeding Section Meeting held at Wädenswil/Einsiedeln, Switzerland from August 30 to September 3, 1993. It gives an overview of the latest trends in temperate fruit breeding in Europe and overseas. Three subjects were considered in special workshops: durability of scab resistance in apple, biotechnology and molecular markers. One important aim of modern fruit breeding is stable resistance to pests and diseases. Molecular markers might help to identify the genetic basis of important characters related to disease and pest resistance and components of yield and quality. Gene transfer has been successfully applied in several fruit species. However, public opinion in many countries does not favour this new technology and its products. Despite these new approaches, traditional breeding methods still predominate; many aspects of traditional breeding are considered in this book. Genetic resources and their exploitation are dealt with in a special chapter. Aspects of breeding minor crops such as walnut, almond, hippophae, cornel, etc. are also considered. Progress in Temperate Fruit Breeding is meant for fruit breeders, pomologists, lecturers, students and growers.

Download or read book Landscape Ecology in Asian Cultures written by Sun-Kee Hong and published by Springer Science & Business Media. This book was released on 2010-12-25 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cultural landscapes are a product of the interactions between humans and natural settings. They are landscapes and seascapes that are shaped by human history and land use. Socioeconomic processes especially, but also environmental changes and natural disturbances, are some of the forces that make up landscape dynamics. To understand and manage such complex landscapes, interdisciplinary and transdisciplinary approaches are necessary, emphasizing the integration of natural and social sciences and considering multiple landscape functions. The spatial patterns of Asian landscapes are strongly related to human activities and their impacts. Anthropogenic patterns and processes have created numerous traditional cultural landscapes throughout the region, and understanding them requires indigenous knowledge. Cultural landscape ecology from a uniquely Asian perspective is explored in this book, as are the management of landscapes and land-use policies. Human-dominated landscapes with long traditions, such as those described herein, provide useful information for all ecologists, not only in Asia, to better understand the human–environmental relationship and landscape sustainability.

Download or read book Genetics and Genomics of Papaya written by Ray Ming and published by Springer Science & Business Media. This book was released on 2013-08-13 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews various aspects of papaya genomics, including existing genetic and genomic resources, recent progress on structural and functional genomics, and their applications in papaya improvement. Organized into four sections, the volume explores the origin and domestication of papaya, classic genetics and breeding, recent progress on molecular genetics, and current and future applications of genomic resources for papaya improvement. Bolstered by contributions from authorities in the field, Genetics and Genomics of Papaya is a valuable resource that provides the most up to date information for papaya researchers and plant biologists.

Download or read book Terra 2008 written by Leslie Rainer and published by Getty Publications. This book was released on 2011-06-14 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Download or read book Medicinal and Aromatic Plants of the World Africa Volume 3 written by Mohamed Neffati and published by Springer. This book was released on 2017-09-07 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume in the series is devoted to Africa, a continent that possesses a vast treasure of medicinal plants and has produced some exclusive materials for the world market. This volume is expected to strengthen the medicinal plant sector in African countries by making comprehensive information on medicinal and aromatic plants available to policy-makers and entrepreneurs. It can be used to frame effective policies and create an environment conducive to the growth of the plant-based medicine industry, bringing economic benefit to African nations. It will help health organizations to improve the health of their people by using their own resources and a less expensive system of medicine, which is accepted by African society. It could also lead scientific communities to increase R&D activities in the field.
