Download or read book Plant Breeding Reviews Volume 12 written by Jules Janick and published by John Wiley & Sons. This book was released on 2010-04-22 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Breeding Reviews presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. Many of the crops widely grown today stem from a very narrow genetic base; understanding and preserving crop genetic resources is vital to the security of food systems worldwide. The emphasis of the series is on methodology, a fundamental understanding of crop genetics, and applications to major crops. It is a serial title that appears in the form of one or two volumes per year.

Download or read book Plants for Arid Lands written by G.E. Wickens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economic plants have been defined by SEPASAT as those plants that are utilised either directly or indirectly for the benefit of Man. Indirect usage includes the needs of Man's livestock and the maintenance of the environment; the benefits may be domestic, commercial or aesthetic. Economic plants constitute a large and so far uncalculated percentage of the quarter of a million higher plants in the World today. However, it has been calculated that 10% (25 000) of these species are now on the verge of extinction and extinction means that a genetic resource that could be of benefit to Man will be lost for ever. Furthermore, for every species lost an estimated 10-30 other dependent organisms are also doomed. Fewer than 1 per cent of the World's plants have been sufficiently well studied for a true evaluation of the potential floral wealth awaiting discovery, not only in the rain forests, which man is now actively destroying at a rate of 20 ha a minute, but also in the very much neglected dry areas of the World.

Available in PDF, EPUB and Kindle. Book excerpt: This book follows the work of the 'Good Roots Project' - a multi-year forestry and agriculture research project in the Philippines. The scheme is an attempt on the part of industry, science and the government to better understand the processes of deforestation and initiate a strategy by which stressed upland ecosystems can be returned to productive stability. This comparative study aims quite simply, to help the farmers of the island to help themselves. Ben Wallace the director of the study investigates the issues surrounding the project, how the initiatives have been implemented, and the future for the island as the population growth rates continue to expand and more land is increasingly given over to agriculture.
