Book Description
The cultivation of rice in Japan has suffered from damage caused by baka nae disease, in which rice seedlings show abnormal growth (elongation) as the result of infection by a plant pathogen. Investigation of the taxonomy of this pathogen led to the commencement of gibberellin (GA) research among Japanese plant pathologists, who later identified it as Gibberella jujikuroi, its other name being Fusarium moniliforme. In 1926, Kurosawa demon strated the occurrence of an active principle in the culture media of fungus that showed the same symptoms as those of the rice disease. In 1938, this finding was followed by the successful isolation of the active principles as crystals from the culture filtrate. This was achieved by the Japanese agri cultural chemists Yabuta and Sumiki, of The University of Tokyo, who named these active principles gibberellins A and B. Following World War II, this discovery attracted the interest of scientists around the world, and research on GA was pursued on a worldwide scale. One of the most outstanding discoveries in GA research after the isolation of GA as the metabolite of the plant pathogen must be the isolation and characterization of GAs from tissues of higher plants by the MacMillan group, West and Phinney, and the Tokyo University group in 1958 and 1959. Thus, GAs have been recognized as one of the most important classes of plant hormones.

Book Description
This is an up-to-date comprehensive text and reference on vegetable production in America and Canada for vegetable growers, handlers and marketers. Divided into three parts, this book discusses principles of vegetable production, explores the science and technology of vegetable crops (covering 12 major crop areas) and provides a glossary of terms used throughout. Nonnecke relates the most useful technology to each topic covered and emphasizes the key role of good husbandry as well as the opportunity for each region to deliver seasonably or year-round abundant, high-quality produce.

Book Description
This anchor volume to the series Managing Global Genetic Resources examines the structure that underlies efforts to preserve genetic material, including the worldwide network of genetic collections; the role of biotechnology; and a host of issues that surround management and use. Among the topics explored are in situ versus ex situ conservation, management of very large collections of genetic material, problems of quarantine, the controversy over ownership or copyright of genetic material, and more.

Book Description
Successful vegetable production in a modern competitive market requires an understanding of many more factors than the biology of crops and the production techniques involved. This major new textbook brings the science and practice of vegetable production right up to date by addressing modern culture techniques and the recent challenges of consumer demand facing producers today. It introduces vegetable production from the perspective of producing high quality produce that satisfies the needs of the modern consumer. Beginning with the basics of how vegetables are grown using high and low input methods, including organic and sustainable production techniques, the book goes on to introduce and discuss many topics covered less comprehensively in older texts, including Good Agricultural Practices to improve quality, reduce biological contamination and secure food safety; water management; cropping systems; plasticulture; protected culture and mineral nutrition. Vegetable Production and Practices also introduces the use of molecular biology for genetic improvement of crops. Issues specific to individual vegetable crops are addressed by family, including their diseases, harvesting, quality attributes and other issues of increasing importance to consumers, including the role of vegetables in human health. Professor Gregory E. Welbaum has a long history of teaching successful courses in horticulture at Virginia Tech and other universities in the US and worldwide. Vegetable Production Practices has been specifically designed to accompany courses in vegetable crop production, so is ideally suited to inspire students in crop and horticultural sciences, as well as provide a useful reference for experienced practitioners.
