Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Insects and Seed Collection Storage Testing and Certification written by T.T. Kozlowski and published by Elsevier. This book was released on 2012-12-02 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed Biology: Insects, and Seed Collection, Storage, Testing, and Certification, Volume III brings together a large body of important information on seed biology. The book describes seed collection, identification, storage, testing, and certification. It also considers insects that directly affect seeds, seed-producing organs, or seed-bearing structures of plants. Organized into six chapters, this volume begins by outlining man's dependency on seeds as source of food, fiber, spices, beverages, oils, vitamins, and drugs. Harmful effects of seeds are also mentioned. Separate chapters focus on seed development, dissemination, germination (including metabolism, environmental control, internal control, dormancy, and seed and seedling vigor), protection from diseases and insects, longevity, and deterioration. The book concludes with a discussion on the certification of field and tree seeds, the Organization for Economic Cooperation and Development certification schemes, and trends in seed certification. This book is a valuable source of information for seed producers and users as well as various groups of research biologists and teachers, including agronomists, plant anatomists, biochemists, ecologists, entomologists, foresters, horticulturists, plant pathologists, and plant physiologists.
