Postharvest Physiology And Pathology Of Vegetables

Focusing exclusively on postharvest vegetable studies, this book covers advances in biochemistry, plant physiology, and molecular physiology to maximize vegetable quality. The book reviews the principles of harvest and storage; factors affecting postharvest physiology, calcium nutrition and irrigation control; product quality changes during handling and storage; technologies to improve quality; spoilage factors and biocontrol methods; and storage characteristics of produce by category. It covers changes in sensory quality such as color, texture, and flavor after harvest and how biotechnology is being used to improve postharvest quality.

This book, chock full of color illustrations, addresses the main postharvest physiological disorders studied in fruits and vegetables. For a wide variety of fruits and vegetables, Postharvest Physiological Disorders in Fruits and Vegetables describes visual symptoms, triggering and inhibiting mechanisms, and approaches to predict and control these disorders after harvest. Color photographs illustrate the disorders, important factors, physiology, and management. The book includes a detailed description of the visual symptoms, triggering and inhibiting mechanisms, and possible approaches to predict and control physiological disorders. The mechanisms triggering and inhibiting the disorders are discussed in detail in each chapter, based on recent studies, which can help readers better understand the factors regulating each disorder. The description of possible approaches to predict and control each disorder can help growers, shippers, wholesalers, and retailers to determine the best management practices to reduce disorder incidence and crop losses. Features: Presents visual symptoms of postharvest physiological disorders that will help readers to precisely identify the disorders in fruits and vegetables Details mechanisms triggering and inhibiting the postharvest disorders Explains possible approaches to predict and control these disorders Suggests the best postharvest management approaches for each crop Although there are many scientific publications on postharvest physiological disorders, there are no recent reviews or books putting together the most recent information about the mechanisms regulating, as well as about the possible approaches to predict and control these disorders.

Optimal distribution of fresh horticultural products entails prolonging their freshness and nutritional quality as long as possible after harvest. A major limitation to their marketing is decay after harvest, which is caused primarily by fungal pathogens. Postharvest Pathology of Fresh Horticultural Produce provides a comprehensive resource of information about the biology and control of postharvest diseases of many fresh horticultural products, citing sources from appropriate literature of any age, rather than only the most recent. The etiology and symptoms of postharvest diseases and the biology of postharvest pathogens are reviewed by leading experts, who are familiar with many of world’s most popular fresh fruits and vegetables and the diseases that affect them. Key aspects related to infection and epidemiology, methods to minimize postharvest decay losses, including use of conventional fungicides and alternative management strategies, harvest and handling practices, and other aspects are described for the most significant temperate, subtropical, and tropical fruits as well as fruit-like vegetables and leafy vegetables. Features: Provides comprehensive academic and practical reviews of postharvest diseases of fresh fruits and vegetables Discusses the economic importance, etiology, and epidemiology of the most significant postharvest diseases Includes quality color plates that allow the practical identification of disease symptoms Explains practical postharvest disease management actions, including the use of conventional fungicides and alternatives to their use The authors summarize a massive quantity of published information, and often apply their own considerable practical experience to identify and interpret the most significant information. This book is a valuable and comprehensive resource for industry professionals, academics, educators, students, consultants, pest control advisors, regulatory personnel, and others interested in this subject.

Emphasis in agricultural research for many years has concen trated on crop production. This emphasis has become more important in recent years with the realization that the population worldwide is outstripping the food supply. There is, however, another side to increasing the availability of the food supply. This simply involves preservation of the harvested crop·for human consumption. The losses incurred in harvesting, handling, transportation, storage and marketing crops have become a greater problem as the distance from the farm to the ultimate consumer increases. In the Western world where modern transportation, storage facilities, and marketing technology are widely used, post-harvest technology requires a large input of energy which increases costs considerably. There fore, losses are more significant and the ability to provide fresh fruits and vegetables, out of season, at reasonable costs will depend on reduced post-harvest losses throughout the marketing chain from the farm gate to the ultimate consumer. The reduction in post-harvest losses depends on proper use of current technology and further developments derived from a broad spectrum of scientific disciplines. Biochemistry, plant physiology, plant pathology, horticulture, agronomy, physics, engineering and agricultural economics, all provide knowledge which has been useful and will be useful in the future for improving post-harvest technol ogy and crop preservation. This volume records the Proceedings of the NATO Advanced Study Institute on Post-Harvest Physiology and Crop Preservation, held at Sounion, Greece, April 28 - May 8, 1981.

Fruits and vegetables are an important part of a healthy diet. However, one third of fruit and vegetables are lost after harvest every year. Most losses are caused by pathogen (mostly fungi) infections, which lead to postharvest decay. In addition, some postharvest fungal pathogens can produce toxic secondary metabolites (i.e. mycotoxins) during their infecting periods. Mycotoxin contamination may cause serious food safety issues. At present, the use of synthetic fungicides is still the main means to control postharvest diseases. However, the development of resistance in fungal pathogens to fungicides and the growing public concern over the health and environmental risks associated with high levels of pesticides in fruits and vegetables have urged researchers to develop alternative methods of disease control. A deeper understanding of the infecting mechanisms of postharvest pathogens will provide great insight into developing new controlling strategies.
