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.
Download or read book Biology of the Plant Bugs Hemiptera Miridae written by Alfred George Wheeler and published by Cornell University Press. This book was released on 2001 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant bugs--Miridae, the largest family of the Heteroptera, or true bugs--are globally important pests of crops such as alfalfa, apple, cocoa, cotton, sorghum, and tea. Some also are predators of crop pests and have been used successfully in biological control. Certain omnivorous plant bugs have been considered both harmful pests and beneficial natural enemies of pests on the same crop, depending on environmental conditions or the perspective of an observer.As high-yielding varieties that lack pest resistance are planted, mirids are likely to become even more important crop pests. They also threaten crops as insecticide resistance in the family increases, and as the spread of transgenic crops alters their populations. Predatory mirids are increasingly used as biocontrol agents, especially of greenhouse pests such as thrips and whiteflies. Mirids provide abundant opportunities for research on food webs, intraguild predation, and competition.Recent worldwide activity in mirid systematics and biology testifies to increasing interest in plant bugs. The first thorough review and synthesis of biological studies of mirids in more than 60 years, Biology of the Plant Bugs will serve as the basic reference for anyone studying these insects as pests, beneficial IPM predators, or as models for ecological research.

Download or read book Seed Production written by Miller F. McDonald and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 755 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
