We initiated research studies on the postharvest physiology of cut flowers almost 20 years ago, when the floriculture industry in Poland began to grow. At that time, like most flower growers in our country, we discovered cut flowers preserve their good appearance longer if kept in a vase with water rather than in dry storage. We then began intensive reading of various horticultural and other specialty journals, and we learned that many scientists had made the same dis covery long before and had gone even further, showing that sucrose and certain chemicals added to the vase water prolong the vase life of flowers much better than water alone. In the meantime, we learned that in the Netherlands, the United States, Israel, and elsewhere, great progress has been made in the postharvest treatment of flowers through the use of floral preserva tives; grading, packing, and transportation procedures; and the organization of trade. In all these countries, researchers generously offered their information to growers, wholesalers, florists, and indi vidual flower lovers eager to improve flower quality and keepability. We collected much of the practical information from various countries with the intention of using it in research projects con cerning the postharvest physiology of floricultural commodities.
Note for the electronic edition: This draft has been assembled from information prepared by authors from around the world. It has been submitted for editing and production by the USDA Agricultural Research Service Information Staff and should be cited as an electronic draft of a forthcoming publication. Because the 1986 edition is out of print, because we have added much new and updated information, and because the time to publication for so massive a project is still many months away, we are making this draft widely available for comment from industry stakeholders, as well as university research, teaching and extension staff.
Cactus plants are precious natural resources that provide nutritious food for people and livestock, especially in dryland areas. Originally published in 1995, this extensively revised edition provides fresh insights into the cactus plant’s genetic resources, physiological traits, soil preferences and vulnerability to pests. It provides invaluable guidance on managing the resource to support food security and offers tips on how to exploit the plant’s culinary qualities.

This book presents several pre- and postharvest strategies that have been developed to modify these physiological activities, resulting in increased shelf life. The book also discusses the best technologies that positively influence quality attributes of the produce, including senescenal changes and, afterwards, the consumers’ decision to purchase the product in the marketplace. With contributions from experts with experience in both developed and developing regions, the book includes chapters covering thorough discussions on postharvest management strategies of fresh horticultural commodities.
Consideration of the interactions between decisions made at one point in the supply chain and its effects on the subsequent stages is the core concept of a systems approach. Postharvest Handling is unique in its application of this systems approach to the handling of fruits and vegetables, exploring multiple aspects of this important process through chapters written by experts from a variety of backgrounds.Newly updated and revised, this second edition includes coverage of the logistics of fresh produce from multiple perspectives, postharvest handing under varying weather conditions, quality control, changes in consumer eating habits and other factors key to successful postharvest handling.The ideal book for understanding the economic as well as physical impacts of postharvest handling decisions.Key Features:*Features contributions from leading experts providing a variety of perspectives*Updated with 12 new chapters*Focuses on application-based information for practical implementation*System approach is unique in the handling of fruits and vegetables
This book, the second of two volumes on the Gentianaceae, is devoted to aspects of biotechnology and their applications. It consists of 18 chapters and covers micropropagation by means of organogenesis or somatic embryogenesis, and single cell manipulation of various species belonging to the horticultural genera Blakstonia, Centaurium, Gentiana, Gentianalla and Swertia. Furthermore, the application of somatic cell hybridization, haploidization and genetic variation arising from tissue and organ culture for the production of plants with new horticultural traits, such as new flower colors or sizes, or with special pharmaceutical values, is treated in detail. Also discussed are molecular markers that facilitate breeding and cultivar identification, the preservation of genetic resources by cryopreservation, the postharvest physiology of cut Gentian flowers and potted plants, and different analytical methods for the evaluation of Gentians as sources of secondary metabolites, such as xanthones and flavonoids, secoiridoids and C-glucoflavonoids, and their positive impacts on human health. This volume as well as the companion book The Gentianaceae – Volume 1: Characterization and Ecology will serve as key reference works for scientists and students in the fields of botany, plant breeding, biotechnology and horticulture, as well as professional gardeners.
