DOWNLOAD EBOOKThis study reproduces one "Report of Meetings" & six "Bulletins" from the Committee on Common Problems of Genetics, Paleontology, & Systematics. This Committee operated as an administrative unit of the National Research Council, part of the U.S. Nat. Acad. of Science. It was launched in 1943, blossomed for two years, then served as a cornerstone for other cooperative projects. The Committee provided a crucial foothold for those seeking a synthetics view of evolution in 1940s America. These forgotten documents show the Committee at work: building coalitions, defining priorities, & negotiating a common vision. They also show factions within the Committee competing for the leadership of this emerging community. Photo.

DOWNLOAD EBOOKSeed 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.
