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.

This publication provides an approach by which conservationists can determine whether or not long-term seed storage is feasible for a particular species, i.e. whether or not that species shows orthodox seed storage behaviour, and provides advice on the implementation of the protocol, examples of ways in which the results from seed storage studies could be misinterpreted due to confounding factors, as well as several alternative approaches for estimating seed storage behaviour prior to carryng out actual investigations with the seeds. In particular, the latter section introduces the concept of a multicriteria approach for estimating seed storage behaviour.

Maintain viability with these techniques for proper seed storage!Healthy, viable seeds are the foundation for sustainable crop production, while poorly kept seeds can result in low germination and crop loss. Seed Storage of Horticultural Crops suggests appropriate strategies to help farmers and breeders store seeds of all kinds.

Revised and expanded throughout, this latest edition of the bestselling Seeds Handbook: Biology, Production, Processing, and Storage includes valuable information on all areas of seed biology, production, and processing. The author, one of the most respected and prolific scientists in the field, identifies current developments in seed testing and certification, storage, transportation, and distribution. Tracking the evolution and advancement of seed industries and technologies, he fully covers the development and supply of high-quality seeds for every key agronomic and horticulture crop. Contains methods to enhance the genetic and physiological characteristics of more than 80 major and minor crops With an abundance of current research and additional figures and illustrations, this edition of the Seeds Handbook offers chapters on modern biotechnological issues such as the production of synthetic seeds, loss-reduction biotechnologies, and new strategies in the seed production industry. It provides in-depth information on burgeoning areas of seed science including tissue culture and cellular totipotency, induction and regeneration protocols, development and maturation, hormone requirements, drying and storage of somatic embryos, protective encapsulation, and crop applications. With an eye to the future, it looks at challenges in the provision and enhancement of seeds for crop plants, practical methods of seed production and micropropagation, genetically modified seeds, and world food security.
