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.
Book Synopsis Ornamental Crops by : Johan Van Huylenbroeck
Download or read book Ornamental Crops written by Johan Van Huylenbroeck and published by Springer. This book was released on 2018-07-25 with total page 888 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ornamental plants are economically important worldwide. Both growers and consumers ask continuously for new, improved varieties. Although there are numerous ornamental species, ornamental plant breeding and plant breeding research is mainly limited to some major species. This book focuses on the recent advances and achievements in ornamental plant breeding. The first part of the book focuses on plant traits and breeding techniques that are typical for ornamental plants. Eminent research groups write these general chapters. For plant traits like flower colour or shape, breeding for disease resistance and vase or shelf life are reviewed. General technical plant breeding chapters deal with mutation breeding, polyploidisation, in vitro breeding techniques and new developments in molecular techniques. The second part of the book consists of crop-specific chapters. Here all economically major ornamental species are handled together with selected representative species from different plant groups (cut flowers, pot plants, woody ornamental plants). In these crop-specific chapters, the main focus is on recent scientific achievements over the last decade.
Book Synopsis Species Concepts in Biology by : Frank E. Zachos
Download or read book Species Concepts in Biology written by Frank E. Zachos and published by Springer. This book was released on 2016-10-05 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frank E. Zachos offers a comprehensive review of one of today’s most important and contentious issues in biology: the species problem. After setting the stage with key background information on the topic, the book provides a brief history of species concepts from antiquity to the Modern Synthesis, followed by a discussion of the ontological status of species with a focus on the individuality thesis and potential means of reconciling it with other philosophical approaches. More than 30 different species concepts found in the literature are presented in an annotated list, and the most important ones, including the Biological, Genetic, Evolutionary and different versions of the Phylogenetic Species Concept, are discussed in more detail. Specific questions addressed include the problem of asexual and prokaryotic species, intraspecific categories like subspecies and Evolutionarily Significant Units, and a potential solution to the species problem based on a hierarchical approach that distinguishes between ontological and operational species concepts. A full chapter is dedicated to the challenge of delimiting species by means of a discrete taxonomy in a continuous world of inherently fuzzy boundaries. Further, the book outlines the practical ramifications for ecology and evolutionary biology of how we define the species category, highlighting the danger of an apples and oranges problem if what we subsume under the same name (“species”) is in actuality a variety of different entities. A succinct summary chapter, glossary and annotated list of references round out the coverage, making the book essential reading for all biologists looking for an accessible introduction to the historical, philosophical and practical dimensions of the species problem.
