Historical Geography of Crop Plants
Author: Jonathan D. SauerPublisher: Routledge
ISBN: 1351440624
Category : Science
Languages : en
Pages : 324
Book Description
Historical Geography of Crop Plants is devoted to a variety of staple and food crops, as well as fodder, fiber, timber, rubber, and other crops. The origins and histories of many of these crops have been clarified only recently by new research. The book has been arranged alphabetically by family and higher taxa for easy reference. Within families, species and cultivars are listed chronologically and geographically. The taxonomy and geography of probable wild progenitors have been outlined, and archeological evidence (when available) and historical evidence on region and domestication are traced. The subsequent evolution and spread of many domesticated species are examined, and the reasons behind the diversity in crop histories are explored. Historical Geography of Crop Plants will be a useful reference for botanists, economic botanists, ethnobiologists, agronomists, geographers, and others interested in the subject.

Author: Handbook of Environmental Physiology of Fruit Crops
Author: Bruce SchafferPublisher: CRC Press
ISBN: 1351442791
Category : Science
Languages : en
Pages : 368
Book Description
These exciting new companion handbooks are the only ones of their kind devoted solely to the effects of environmental variables on the physiology of the world's major fruit and nut crops. Their cosmopolitan scope includes chapters on tropical and temperate zone species written by scientists from several continents. The influence of environmental factors, such as irradiance, temperature, water and salinity on plant physiology and on vegetative and reproductive growth, is comprehensively discussed for each crop. In addition to being a thorough and up-to-date set of textbooks, the organzation of the two volumes makes them an excellent reference tool. Each chapter focuses on a single crop, or a group of genetically or horticulturally related crop, and is appropriately divided into subsections that address individual environmental factors. Some chapters emphasize whole-plant physiology and plant growth and development, while other chapters feature theoretical aspects of plant physiology. Several chapters provide botanical background discussions to enhance understanding of the crop's response to its environment.

Book Description
The objects of the American Meteorological Society are "the development and dissemination of knowledge of meteorology in all its phases and applications, and the advancement of its professional ideals." The organization of the Society took place in affiliation with the American Association for the Advancement of Science at Saint Louis, Missouri, December 29, 1919, and its incorporation, at Washington, D. C., January 21, 1920. The work of the Society is carried on by the Bulletin, the Journal, and Meteorological Monographs, by papers and discussions at meetings of the Society, through the offices of the Secretary and the Executive Secretary, and by correspondence. All of the Americas are represented in the membership of the Society as well as many foreign countries.
A Study and Review of the Japanese Green and the Korean Ring-necked Pheasants

Pages : 76
Book Description
Following a general review of the taxonomy, distribution and descriptions of the Japanese green pheasants (Phasianus versicolor) and the Korean and Manchurian ring-necked pheasants (P. c. karpowi and P. c. pallasi) detailed consideration is given to their habitat and cover preferences, climatic and food and water requirements, general habits and reproductive capacity. Their relation to agriculture, to other game birds within their native range, an evaluation of their potentialities for trial introduction into the United States and suggestions for game farm propagation are also discussed.
