This book was released on 2012-12-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: view than its own proper males should fecundate each blossom." ANDREW KNIGHT Philosophical Transactions, 1799 Pollination mechanisms and reproduction have a decisive bearing upon rational procedures in plant breeding and crop production. This book intends to furnish' under one cover an integrated botanical, genetical and breeding-methodologi cal treatment of the reproductive biology of spermatophytes mainly angiosperms; it is based on an advanced topical course in plant breeding taught at the Hebrew University of Jerusa lem. We have tried to present a coverage which is concise, but as comprehensive as possible, of the pollination mechanism and modes of reproduction of higher plants, and to illustrate topics, whenever practicable, by examples from cultivated plants. Nevertheless, some relevant publications may have escaped our attention or may not be mentioned because of various limitations. The book is organized into three parts. The first part starts with an evaluation of the significance of the different pollination mechanisms for plant breeding and crop produc tion, describes modes of reproduction in higher plants and discusses ecology and dynamics of pollination. The second part is devoted to crops propagated by self pollination and describes specific breeding procedures for such crops. The third part details sexual reproduction in higher plants and handles three mechanisms involved in the prevention of self pollination and their utilization in plant breeding: sex expres sion, incompatibility, and male sterility.

Download or read book Self Incompatibility in Flowering Plants written by Vernonica E. Franklin-Tong and published by Springer Science & Business Media. This book was released on 2008-07-30 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Great progress has been made in our understanding of pollen-pistil interactions and self-incompatibility (SI) in flowering plants in the last few decades. This book covers a broad spectrum of research into SI, with accounts by internationally renowned scientists. It comprises two sections: Evolution and Population Genetics of SI, Molecular and Cell Biology of SI Systems. The reader will gain an insight into the diversity and complexity of these polymorphic cell-cell recognition and rejection systems. Heteromorphic and homomorphic SI systems and our current understanding of the evolution and phylogeny of these systems, based on the most recent molecular sequence data, are covered. Further, the book presents major advances in our knowledge of the pistil and pollen S-determinants and other unlinked components involved in SI, as well as the apparently diverse cellular regulatory mechanisms utilised to ensure inhibition of “self” pollen.

Download or read book Status of Pollinators in North America written by National Research Council and published by National Academies Press. This book was released on 2007-05-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Download or read book Fertilization in Higher Plants written by Mauro Cresti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biotechnological methods are opening new ways in plant breeding. They allow novel strategies for improving crop productivity and quality, especially in the agrofood sector. The molecular mechanisms underlying these biotechnological approaches are presented here. Topics included are: pollen development, pollen tube growth, macrosporogenesis and fertilization and the effects of pesticides on sexual plant reproduction. Fertilization in higher plants is a complex process consisting of two events, the fusion of the egg with one sperm cell resulting in the diploid zygote, and the fusion of embryosac nuclei with another sperm cell, leading to a triploid endosperm. This "double fertilization" is preceded by the pollination process and a long lasting interaction between the dipoid pistil and the haploid pollen tube (progamic phase). Fertilization of flowering plants results in the formation of seeds and fruits, our basic food supply.
