The Growth of Bulbs: Applied Aspects of the Physiology of Ornamental Bulbous Crop Plants presents an account of ornamental bulbs as plants and as crops, with emphasis on scientific aspects of bulb growing, bulb treatment, and bulb forcing. While the account is biased towards British bulb growing, it also introduces bulb growing in other parts of the world, especially in the Netherlands, the United States, Israel, and Japan. The book's opening chapter discusses the origins of bulbous plants, how they became important as crop plants, and how the various forms now widely grown had been developed. This is followed by separate chapters on bulb types, structure, morphology, development and periodicity; bulb growth and productivity; flower initiation and differentiation; and the storage of bulbs. Subsequent chapters cover bulb physiology and metabolism, bulb disorders, and bulb pests and diseases. The book concludes with reflections on the form of the plant of the future.

Representing the most comprehensive review of the physiological research conducted on 61 genera of ornamental geophytes, this book covers the basic aspects of world production, horticultural utilization, botanical descriptions and origins, bulb growth and development and flowering, production systems, diseases, insects, plant breeding and the economics related to flower bulbs. This is the first publication to allow access to this research in one single volume, with each genera chapter being outlined in such a manner that any subject area can be readily accessed without reading the entire chapter. Information is also included on genera that have never been comprehensively reviewed. Written by scientists from all over the world, this book aims to provide a basic orientation for any individuals who are unfamiliar with flower bulbs as well as to serve as a comprehensive, quick-reference text.

Although a great deal of research on ornamental geophytes has been conducted since the beginning of the 1990s, current information has not been comprehensively presented to researchers and horticulturalists. Covering the latest advances in geophytes science, Ornamental Geophytes: From Basic Science to Sustainable Production provides up-to-date revi

Lachenalia cv. Ronina, a new flower bulb variety developed by the ARC-Roodeplaat Vegetable and Ornamental Plant Institute, has excellent characteristics as a flowering pot plant, but information on cultivation practices is limited. Temperature is the most important environmental factor regulating the growth cycle of this flower bulb, therefore three temperature regimes, representing a cool, moderate and warm winter climate, were chosen to manipulate floral development. During this study the bulb structure, development and growth were determined during the bulb preparation phase (year 1) and subsequently the morphology of the bulb was evaluated during the pot plant phase (year 2). Regarding the bulb structure and development, cultivar Ronina has a typical rhythmic, sympodial, modular growth. Bulb growth and module formation is affected by temperature. The low (L TR) and moderate (MTR) temperature regime, which represent the cool and moderate winter climate in South Africa were found to be the best temperature regimes for bulb production. The high (HTR) temperature regime caused bulbs to develop faster, but flower abortion occurred. At the end of the bulb preparation phase, daughter bulbs were observed in the axils of the leaf bases in bulbs of all three temperature regime treatments. Additional inflorescences from underdeveloped growth modules were detected in the axils of the inner leaf bases of bulbs of the high temperature regime. The bulbs as well as the roots are the main sinks for the carbohydrates, whereas the inflorescence and especially the leaves are the main source for soluble sugars. Due to the more stable temperature that was applied in the growth cabinets, the flowering date of bulbs in all three treatments flowered two months earlier than plants growing in the open. During this production phase, simultaneous flowering occurred more within bulbs that were subjected to the LTR during the bulb preparation phase. These bulbs also produced broader leaves with more spots on and better quality inflorescences with a longer keeping ability than those of the higher temperature regimes. A correlation was found between the leaf number and the number of inflorescences of plants in the pot plant phase, grown from LTR treated bulbs. The bulb fresh mass/size at the end of the bulb preparation phase cannot be used as a reliable criterion to predict the quality of the pot plant. By examining the bulb structure at the end of the bulb preparation phase, the quality of the pot plant can be predicted.

This new volume presents some of the latest research trends and areas of improvement to benefit the floriculture industry and to understand its future directions and prospects. The research addresses the global floriculture industry’s shift from a traditional to a commercial focus. The global economy has spurred entrepreneurs to focus on the growing trend of exportoriented floriculture under controlled climatic conditions. The volume also looks at the role of plants in stabilizing the environment and the use of scientific knowledge through research that has changed the perspective of modern floriculture. This new book is a valuable compilation of the latest research work and areas of improvement in floriculture today. Key features: Provides an overview of the global floriculture industry Looks at the role of bulbous ornamentals Considers enhancing consumer-preferred traits in floriculture crops through genetic manipulation Discusses using ornamental plants to stabilize the environment
