En los últimos años la Agroforestería ha atraído la atención de gran número de agrónomos, ecologistas, economistas y otros especialistas que han descubierto el potencial de los sistemas agroforestales, como alternativa ecológicamente sostenible y económicamente viable en las regiones agrícolas del mundo tropical (de Haan et al. 1997). Además, dichos sistemas aparecen como una opción para la reconversión social y ambiental de la ganadería en estas zonas, donde las plantas superiores ofrecen gran diversidad biológica. Cuba se encuentra dentro de este grupo de países (Ruiz y Febles 2003). En este amplio grupo de plantas, los árboles multipropósitos muestran inmenso potencial natural, y un ejemplo de ello lo constituyen los árboles leguminosos forrajeros

During germination, the most resistant stage of the life cycle - the seed - changes to the most sensitive stage, namely the seedling. Therefore, in desert plant species seed dispersal and subsequent germination in the optimum time an place place are particularly critical parameters. Discussed here are the ways and means by which desert plants have adapted through the course of evolution to their extreme environment. Two such strategies which have evolved are a) plants with relatively large and protected seeds which germinate when the chance of seedling survival is high and the risk relatively low or b) those with an opportunistic strategy: minute seeds which germinate after low rainfall under high risk for seedling survival if additional rain does not follow. Most species adopt a combination of the two mechanisms. Species have adapted both genotypically and phenotypically, both aspects of which are also discussed in this thorough text. The reader is provided with a good understanding of the complex influences on each seed traced through from initial development to germination stage regarding germination preparation and subsequent survival.

Principles Of Seed Science And Technology written by Lawrence O. Copeland and has been published by Springer Science & Business Media this book supported file pdf, txt, epub, kindle and other format this book has been release on 2012-12-06 with Science categories.

This Fourth Edition of Principles of Seed Science and Technology, like the fIrst three editions, is written for the advanced undergraduate student or lay person who desires an introduction to the science and technology of seeds. The fIrst nine chapters present the seed as a biological system and cover its origin, development, composition, function (and sometimes nonfunction), performance and ultimate deterioration. The last nine chapters present the fundamentals of how seeds are produced, conditioned, evaluated and distributed in our modern agricultural society. Two new chapters have been added in this fourth edition, one on seed ecology and the second on seed drying. Finally, revisions have been made throughout to reflect changes that have occurred in the seed industry since publication of the Third Edition. Because of the fundamental importance of seeds to both agriculture and to all of society, we have taken great care to present the science and technology of seeds with the respect and feeling this study deserves. We hope that this feeling will be communicated to our readers. Furthermore, we have attempted to present information in a straight-forward, easy-ta-read manner that will be easily understood by students and lay persons alike. Special care has been taken to address both current state-of-the-art as well as future trends in seed technology.

Growing Exotic Forests written by Bruce Zobel and has been published by Wiley-Interscience this book supported file pdf, txt, epub, kindle and other format this book has been release on 1987 with Nature categories.

This is the first text/reference on growing exotic forests, bringing together information that heretofore was widely scattered throughout the journal literature, and is the only work to cover both tropical and temperate climes in one volume. Exotic means not native to the region - now, exotic forestry is spreading incredibly rapidly. This volume covers basic concepts, widely illustrated with examples from all over the world, based on the authors' extensive experience in the field. Written in a straightforward manner, the text is understandable to both the professional and the layman. Topics covered include genetic improvement of exotics - developing and using land races - genotype X environment interaction, limitation to production in and unusual problems with exotic forests, gene conservation and exotic forestry, and much more.
