Description : Buried viable seed banks are a fundamental aspect of seed plant biology. They play a key role in the conservation and restoration of plant communities and the response of plants to changing land use and climate. There is almost no area of plant ecology in which seed banks are not implicated. Despite several recent reviews of the ecology of seed banks, there has previously been no single source of data on seed persistence in individual species. This volume, which compiles the available data from the nineteenth century up to the end of 1993, provides this source for the 1189 members of the northwest European flora. The text describes the criteria for inclusion of data and discusses seed classification systems, the relative representation of different habitats, methods and taxa, and challenges for future research. Includes PC disc with database in searchable format.

Description : The evolution of seeds has contributed to one of the most astonishing explosions of biodiversity in history. Indeed, most plants employ seeds as reproductively crucial structures. Everything about seeds involves timing. Seeds result from fertilization occurring when conditions are favorable, i.e., after sufficient resources have been devoted to reproductive tissues. Furthermore, seeds help ensure that there are the necessary stored materials for the early growth and development of the next generation of plants. And finally, seeds allow the next generation to wait in a form of suspended animation until conditions for the next generation are once again favorable. This book about seeds focuses upon their two most important functions-dormancy and germination. The topics covered include the types of dormancy, theories of the relationship between dormancy and germination, the timing of germination, the various factors that control germination, and the general aspects of germination in different sorts of habitats. Ecologists, plant scientists, agriculturists, foresters-indeed, anyone interested in plants and their life cycles will want to add this title to his or her library.

Description : Faith in a Seed contains the hitherto unpublished work The Dispersion of Seeds, one of Henry D. Thoreau's last important research and writing projects, and now his first new book to appear in 125 years.With the remarkable clarity and grace that characterize all of his writings, Thoreau describes the ecological succession of plant species through seed dispersal. The Dispersion of Seeds, which draws on Charles Darwin's theory of natural selection, refutes the then widely accepted theory that some plants spring spontaneously to life, independent of roots, cuttings, or seeds. As Thoreau wrote: "Though I do not believe a plant will spring up where no seed has been, I have great faith in a seed. Convince me that you have a seed there, and I am prepared to expect wonders." Henry D. Thoreau's Faith in a Seed, was first published in hardcover in 1993 by Island Press under the Shearwater Books imprint, which unifies scientific views of nature with humanistic ones. This important work, the first publication of Thoreau's last manuscript, is now available in paperback. Faith in a Seed contains Thoreau's last important research and writing project, The Dispersion of Seeds, along with other natural history writings from late in his life. Edited by Bradley P. Dean, professor of English at East Carolina University and editor of the Thoreau Society Bulletin, these writings demonstrate how a major American author at the height of his career succeeded in making science and literature mutually enriching.

Description : Seed is the source of future plants or foods, is the storage place of culture of history, is the first link in the food chain, is the ultimate symbol of food security. Seed is the source of life. Seeds are basic in crop production. No agricultural practice can improve a crop beyond the limits set by the seed. Quality seed is the key for successful agriculture, which demands each and every seed should be readily germinable and produce a vigorous seedling ensuring high yield. “Care with the seed and joy with the harvest” and “Good seed doesn’t cost it always pays” are the popular adage which enlightens the importance of the quality seed. The farmers always very much interested in the best seed management practices which are safe, environmentally sound and scientifically proven technologies. Understandably, in view of the importance of quality seeds in Agriculture, both as a product and as a means of establishing a crop, most attention at all levels of investigation has been directed to crop seeds. Since seed is a biological entity, deterioration beyond harvest is inevitable. The consequences of low quality seeds are poor germination, low and delayed emergence and weak growth leading to poor field stand and ultimately reflecting on reduced yield. Low productivity could be attributed broadly to use of poor quality seeds. At present to overcome this, several seed enhancement techniques are available for quality upgradation. It has two goals; one is related to seed designing and other to seed functioning. The rationale for pre-sowing seed enhancement techniques is to mobilize the seeds own resources and to augment them with external resources to get maximum improvement in field stand establishment and yield. To achieve this, several physical, physiological and biochemical treatments are available at present to give value addition to seeds. Physiological seed treatments that improve seed performance are based primarily on seed hydration and dehydration. Among several non physiological seed treatments, coating or pelleting can also indirectly improve seed germination, stand establishment and crop productivity.

Description : This toolkit – made available in English, French and Spanish – will be promoted as practical guidance to assist in the implementation of the national seed strategies. It will provide a number of practical capacity building tools for essential stages of the seed value chain and targeted primarily at seed sector practitioners who will participate in special training workshops to acquire pertinent technical knowledge and will be expected in return to create a multiplier effect through further follow-up FFS trainings down to the level of seed traders and farmers. In doing so, the toolkit will be used as guidance for conducting country-led workshops and other training activities aimed at strengthening quality seed delivery systems and seed regulatory mechanisms in selected countries. The development of capacity in the production of high quality seeds, the seed replacement rates, true seed cost and realistic seed pricing mechanisms as well as the role of different stakeholders are of critical importance in the process of the formulation of national seed policies, which is one of the core areas of FAO’s delivery at the national level.

Description : Plant breeders continue to make significant advances in developing high yield ing, adaptable, disease-free crops. These advances, however, are not realized until an efficient seed production system is in place that rapidly increases geneti cally superior crops and makes them available to the consumer in large quantities at a reasonable cost. Successful seed production requires seed to be genetically pure, free of admixtures, and able to establish rapidly a uniform stand. Seed production is a complex process. Rigorous production criteria are followed by both seed producer and seed companies to ensure that high-quality seed is produced and marketed. These criteria become even more stringent in hybrid seed production. This volume identifies the factors most critical in a successful seed production operation. The fundamental considerations common to all seed crops are established in Part I, Principles of Seed Production. From this founda tion, the practices of seed production are provided in detail in Part II, Seed Production of Specific Crops.
