Horticultural crop production plays an important role in the global food supply, and horticultural plants contain numerous health-promoting phytochemicals, such as vitamins, flavonoids, polyphenols, and other secondary metabolites. The formation of yield and nutritional quality depends on the intrinsic characteristics of horticultural crops and environmental conditions. Light is the primary energy source for photosynthesis, and light, ranging from UV to far-red, is a critical factor in regulating plant growth, morphogenesis, development, and metabolic processes. The physiological and molecular regulation of plant processes is related to the intensity, spectrum, direction, photoperiod, and timing of light. And light is the most important environmental factor determining the yield and quality of horticultural crops.

This book presents a comprehensive treatise on the advances in the use of light-emitting diodes (LEDs) for sustainable crop production and describes the latest photomorphogenesis research findings. It introduces readers to the fundamentals and design features of LEDs applicable for plant growth and development and illustrates their advantages over the traditional lighting systems, including cost analyses. Further, it discusses a wide range of applications covering diverse areas of plant sciences relevant to controlled environment agriculture and in vitro plant morphogenesis. The chapters have been written by a team of pioneering international experts, who have made significant contributions to this emerging interdisciplinary field. The book will serve a valuable resource for graduate students, instructors, and researchers in the fields of horticulture, agricultural biotechnology, cell and developmental biology, and precision agriculture. It will also serve well professionals engaged in greenhouse and vertical farming.

An understanding of crop physiology and ecophysiology enables the horticulturist to manipulate a plant’s metabolism towards the production of compounds that are beneficial for human health when that plant is part of the diet or the source of phytopharmaceutical compounds. The first part of the book introduces the concept of Controlled Environment Horticulture as a horticultural production technique used to maximize yields via the optimization of access to growing factors. The second part describes the use of this production technique in order to induce stress responses in the plant via the modulation of these growing factors and, importantly, the way that this manipulation induces defence reactions in the plant resulting in the production of compounds beneficial for human health. The third part provides guidance for the implementation of this knowledge in horticultural production.

This book focuses on light-emitting diode (LED) lighting, mainly for the commercial production of horticultural crops in plant factories and greenhouses with controlled environments, giving special attention to: 1) plant growth and development as affected by the light environment; and 2) business and technological opportunities and challenges with regard to LEDs. The book contains more than 30 chapters grouped into seven parts: 1) overview of controlled-environment agriculture and its significance; 2) the effects of ambient light on plant growth and development; 3) optical and physiological characteristics of plant leaves and canopies; 4) greenhouse crop production with supplemental LED lighting; 5) effects of light quality on plant physiology and morphology; 6) current status of commercial plant factories under LED lighting; and 7) basics of LEDs and LED lighting for plant cultivation. LED lighting for urban agriculture in the forthcoming decades will not be just an advanced form of current urban agriculture. It will be largely based on two fields: One is a new paradigm and rapidly advancing concepts, global technologies for LEDs, information and communication technology, renewable energy, and related expertise and their methodologies; the other is basic science and technology that should not change for the next several decades. Consideration should be given now to future urban agriculture based on those two fields. The tremendous potentials of LED lighting for urban agriculture are stimulating many people in various fields including researchers, businesspeople, policy makers, educators, students, community developers, architects, designers, and entrepreneurs. Readers of this book will understand the principle, concept, design, operation, social roles, pros and cons, costs and benefits of LED lighting for urban agriculture, and its possibilities and challenges for solving local as well as global agricultural, environmental, and social issues.

Photoperiodism is the response to the length of the day that enables living organisms to adapt to seasonal changes in their environment as well as latitudinal variation. As such, it is one of the most significant andcomplex aspects of the interaction between plants and their environment and is a major factor controlling their growth and development. As the new and powerful technologies of molecular genetics are brought to bear on photoperiodism, it becomes particularly important to place new work in the context of the considerable amount of physiological information which already exists on the subject. This innovative book will be of interest to a wide range of plant scientists, from those interested in fundamental plant physiology and molecular biology to agronomists and crop physiologists. - Provides a self-sufficient account of all the important subjects and key literature references for photoperiodism - Includes research of the last twenty years since the publication of the First Edition - Includes details of molecular genetic techniques brought to bear on photoperiodism

The plant factory is a facility that aids the steady production of high-quality vegetables all year round by artificially controlling the cultivation environment (e.g., light, temperature, humidity, carbon dioxide concentration, and culture solution), allowing growers to plan production. By controlling theinternal environment,plant factories can produce vegetables about two to four times faster than by typical outdoor cultivation. In addition, as multiple cultivation shelves (a multi-shelf system) are used, the mass production of vegetables in a small space is facilitated. This research topic presents some new trends on intelligent measuring systems; environment controlled and optimization; flavonoids; phenylpropanoids, transcriptomes, and bacteria.

Basic approaches to maintaining the safety and quality of horticultural produce are the same, regardless of the market to which this produce is targeted. This bulletin reviews the factors which contribute to quality and safety deterioration of horticultural produce, and describes approaches to assuring the maintenance of quality and safety throughout the post-harvest chain. Specific examples are given to illustrate the economic implications of investing in and applying proper post-harvest technologies. Criteria for the assessment of post-harvest needs, the selection of post-harvest technologies appropriate to the situation and context, and for extending appropriate levels of post-harvest information are also discussed.
