An essential reference for students, seed technologists, researchers, and seed industry personnel, this comprehensive guide outlines the most widely performed modern seed quality tests, explores the principles behind them, the history of seed testing, why seeds are tested and when, and sampling, sub-sampling, seed laboratory management, accreditation, and seed quality assurance programs. The authors describe statistical applications to seed testing and tolerances, and they provide a detailed morphological and structural description of seed formation and development. The book examines the testing of genetic traits and transgenic seeds, including DNA and protein genetic purity tests, and cultivar purity identification for conventional seeds. In addition to the most common seed purity and viability tests, tests for seed and seedling vigor, seed-borne diseases and seed moisture determination are also discussed.
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.
This Third Edition of Principles of Seed Science and Technology. like the first two editions. is written for the advanced undergraduate student or lay person who desires an introduction to the science and technology ofseeds. The first eight chapters presentthe seed as abiologicalsystemand coverits origin. development. composition. function (and sometimes nonfunctionJ, performance and ultimate deterioration. The last seven chapters present the fundamentals ofhow seedsare produced. conditioned. evaluated and distributed in our modern agricultural society. A new chapter on seed enhancement has been added to reflect the significant advancements made in the last 10 years on new physiological and molecular biology techniques to further enhance seed performance. 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.

Special care has been taken to address both current state-of-the-art as well as future trends in seed technology. . We believe this Third Edition represents a new level in presenting information that appeals to advanced undergraduate students as well as to those desiring more fundamental information on seed form and function.

For ages, farmers have domesticated plant varieties, while scientists have "made" nature through hybridization and other processes. This give and take-mediated through negotiations, persuasion, the marketplace, and even coercion-has resulted in what we call "nature" and has led to a homogenization of plant crops. Yet homogenization has led to new problems: genetic vulnerability, and the lack of systems to maintain plant germplasm of varieties no longer grown in the fields. This book addresses issues previously viewed as primarily technical concerning the germplasm debate: that is, how, what, and where to store the range of genetic materials necessary to reproduce plants. By examining Brazil, Chile, France, and the United States, the authors show how different cultures respond to the decline in genetic diversity. The findings show that the quest for uniformity in foods, agriculture, and environment eventually threatens everyone. The politicization of this debate is inevitable because the destruction of human cultural diversity goes hand in hand with the destruction of plant varietal diversity. The authors agree that responses to the controversies must involve food security, relinking of food with agriculture and the environment, revaluing traditional knowledge, and rethinking development. They stress that answers will be found not by experts acting unilaterally but through the democratization of scientific and technical exchange.

Seed Quality: Basic Mechanisms and Agricultural Implications focuses on various aspects of seed quality and integrates research at basic and applied levels, supporting high-quality seeds as the basis of higher agricultural productivity. With its clear perspective and interdisciplinary focus on basic and applied aspects of seed quality, this book is immensely useful to students and teachers in many agricultural and botanical disciplines. Because seed quality is a critical component in the economic considerations of the farmer and the seedman alike, Basra looks in-depth at these aspects of seed production: seed viability seed health seed vigor seed testing variety identification crop yield seed storage seed production seed deterioration seed treatments Seed quality is of international agronomic concern, and the recent upsurge of interest in seed quality has accentuated a new awareness regarding its importance in crop production. This book meets the need for information and could form the basis of long-range planning by policymakers on quality assurance and management programs and in the facilitation of international trade. Researchers, students, and teachers in many agricultural and botanical disciplines--seed science and technology in particular--will find this book to be of immense use. It can be used as a handbook for those involved in seed industry and seed testing services. It is recommended for international courses in seed science and technology and seed training programs.
High-quality seed is essential for healthy crops and greater agricultural productivity. At the same time, advances in breeding technology require equivalent advances in seed technology. In order to ensure food security, it is crucial to develop seeds that are high yielding, and resistant to drought, heat, cold, and insects. Gathering the latest research in seed sciences, the book includes contributions on seed production in crops such as legumes, sugar, rice, wheat and other cereals. It discusses a range of topics, like the effect of climate change on seed quality, production and storage; seed rouging; seed certification for different crop species; seed biology; and seed pathologies and their effective management. Integrating basic and applied research, this compendium provides valuable insights for researchers and students in agricultural and life sciences; professionals involved in seed certification and those working in quarantine laboratories; as well as plant pathologists.
