Download or read book Flowering Plants Dicotyledons written by Klaus Kubitzki and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume - the first of this series dealing with angiosperms - comprises the treatments of 73 families, representing three major blocks of the dicotyledons: magnoliids, centrosperms, and hamamelids. These blocks are generally recognized as subclasses in modern textbooks and works of reference. We consider them a convenient means for structuring the hundreds of di cotyledon families, but are far from taking them at face value for biological, let alone mono phyletic entities. Angiosperm taxa above the rank of family are little consolidated, as is easily seen when comparing various modern classifications. Genera and families, in contrast, are comparatively stable units -and they are important in practical terms. The genus is the taxon most frequently recognized as a distinct entity even by the layman, and generic names provide the key to all in formation available about plants. The family is, as a rule, homogeneous enough to conve niently summarize biological information, yet comprehensive enough to avoid excessive re dundance. The emphasis in this series is, therefore, primarily on families and genera.

Download or read book Seeds written by Carol C. Baskin and published by Elsevier. This book was released on 2014-02-20 with total page 1601 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new edition of Seeds contains new information on many topics discussed in the first edition, such as fruit/seed heteromorphism, breaking of physical dormancy and effects of inbreeding depression on germination. New topics have been added to each chapter, including dichotomous keys to types of seeds and kinds of dormancy; a hierarchical dormancy classification system; role of seed banks in restoration of plant communities; and seed germination in relation to parental effects, pollen competition, local adaption, climate change and karrikinolide in smoke from burning plants. The database for the world biogeography of seed dormancy has been expanded from 3,580 to about 13,600 species. New insights are presented on seed dormancy and germination ecology of species with specialized life cycles or habitat requirements such as orchids, parasitic, aquatics and halophytes. Information from various fields of science has been combined with seed dormancy data to increase our understanding of the evolutionary/phylogenetic origins and relationships of the various kinds of seed dormancy (and nondormancy) and the conditions under which each may have evolved. This comprehensive synthesis of information on the ecology, biogeography and evolution of seeds provides a thorough overview of whole-seed biology that will facilitate and help focus research efforts. Most wide-ranging and thorough account of whole-seed dormancy available Contains information on dormancy and germination of more than 14,000 species from all the continents – even the two angiosperm species native to the Antarctica continent Includes a taxonomic index so researchers can quickly find information on their study organism(s) and Provides a dichotomous key for the kinds of seed dormancy Topics range from fossil evidence of seed dormancy to molecular biology of seed dormancy Much attention is given to the evolution of kinds of seed dormancy Includes chapters on the basics of how to do seed dormancy studies; on special groups of plants, for example orchids, parasites, aquatics, halophytes; and one chapter devoted to soil seed banks Contains a revised, up-dated classification scheme of seed dormancy, including a formula for each kind of dormancy Detailed attention is given to physiological dormancy, the most common kind of dormancy on earth

Book excerpt: "There is nothing in the world like this book. It should be in every library and on the bookshelves of all those interested in cacti. The book will be an important resource for plant physiology, agronomy, and horticulture classes at both the undergraduate and graduate level."—Bruce Smith, Brigham Young University "Cacti: Biology and Uses is a landmark publication of one of the world's most unique group of plants. Park Nobel, a leading authority on succulent plants, has assembled a collection of contributions that spans a wide range of issues extending from basic systematics, anatomy, physiology and ecology to considerations of conservation and human uses of this diverse group of plants. This nicely-produced and well-illustrated volume provides a resource that will be of great use to a wide range of scientists, practitioners, and enthusiasts of this plant group."—Harold Mooney, Paul S. Achilles Professor of Environmental Biology, Stanford University
