Book Description
This Joint ISTA and FAO Handbook provides comprehensive guidelines for the setting up and managing of seed testing laboratories, including those that cater to small- and medium-scale seed enterprises and farmers’ cooperatives, which operate in low input production systems. The adherence to the guidelines by seed testing laboratories results in the use of uniform procedures across the board thereby facilitating inter-laboratory transferability of data. This harmonization enhances confidence in seed quality assurance mechanisms. The publication is an update of a previous one that was also jointly published by both organizations in 1969 and revised in 1979 and 1983. Its utility is enhanced by a set of new up-to-date information that builds upon existing data. The Handbook provides guidance on the range of seed testing equipment, procedures, and management systems that have become available in the several decades since the previous editions. Seed testing is a critical component of the seed value chain and is essential for the production of quality seeds, i.e. seeds that are alive, can germinate and produce vigorous seedlings; are healthy and come from lots that meet set thresholds for genetic and analytical purity. The Handbook covers all aspects of seed testing, from laboratory design and equipment selection to sample preparation, testing methods, and data analysis. Importantly, the publication also addresses the challenges of testing seeds in low input systems and provides guidance on how to adapt procedures to these settings. Therefore, it serves as a reference material and training resource for everyone involved in seed quality assurance procedures, in particular the personnel of seed testing laboratories and regulatory agencies; seed producers and farmers. The updated publication represents a significant improvement over previous guidelines, as it incorporates advances in technology and provides guidance on a broader range of testing procedures. The guidelines are designed to be adaptable to different contexts and seed types and include recommendations for quality management systems, proficiency testing, and inter-laboratory comparisons, which are essential for ensuring the accuracy and reliability of seed testing results.

Principles of Seed Science and Technology
Author: Lawrence O. CopelandPublisher: Springer Science & Business Media
ISBN: 1461516196
Category : Science
Languages : en
Pages : 479
Book Description
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.

Book Description
From prehistoric times man has had a pecial s relationship with seed plants - as a source of food, materials for tools, buildings, clothing and pharmaceuticals, and for ornamenting his surroundings for his own delight (probably in that chronological order which, incidentally, also gives some indication ofthe priorities oflife). Today man's most important staple foods are derived directly from seeds as they have been since neolithic times. (It is a sobering thought, as Harlan* has pointed out, that nothing significant has been added to his diet since then. ) From those times he must have learned to collect, conserve and cultivate seeds; and the accumulated experience has been handed down. This book then is part of an ancient tradition, for here we are still primarily concerned with these skills. Seeds are plant propagules comprised of embryos in which growth has been suspended, usually supplied with their own food reserves and protected by special covering layers. Typically they are relatively dry structures compared with other plant tissues and, in this condi tion) they are resistant to the ravages of time and their environment. But resistant is a relative tenn and seeds do deteriorate: the type, the extent and the rapidity of the deterioration, and the factors which control it are important to agronomists, horticulturalists, plant breeders, seedsmen, seed analysts, and those concerned with the conservation of genetic resources.
