however, the stress intensity is controlled in order that biomass formation is not affected The fine-tuned control of production factors such as water, temperature or nutrient availability is only possible during protected cropping In horticulture, this refers to production within, under or sheltered by structures such as covers, artificial shading, plastic tunnels or greenhouses This textbook entitled Controlled Environment Horticulture: Improving Quality of Vegetables and Medicinal Plants describes in detail ways in which the horticulturist can control abiotic and biotic production factors in order to adjust the metabolism of the crop to the production of metabolites that are beneficial when ingested as part of a plant-based diet or as plant-based pharmaceuticals Before guidance in this regard is given, a theoretical background is provided that allows the reader to apply their acquired knowledge to other situations The unique character of the book is that undergraduate and graduate students have written many parts of this textbook In this way, complex plant physiological concepts are presented in a simple and understandable manner, making this book the perfect format for undergraduate students Christoph-Martin Geilfus Berlin, Germany VII Acknowledgements I would like to sincerely thank all the student coauthors, without whose great dedication this book would not have originated My special thanks to Veronika Strauss, Jeffrey J Jones, Adrian Vollmer and Roland Sier who made a strong commitment to the textbook Veronika Strauss helped to proofread all ­chapters, which was greatly appreciated Jeffrey J Jones gave many critical comments that helped to improve many chapters Last, I would like to thank Springer Nature, which made it possible to write this book IX Contents IIntroduction 1Introduction References 2Protected Cropping in Horticulture 2.1 2.2 Horticultural Vegetables 12 Medicinal Plants 14 References 16 3Plant Secondary Compounds 19 3.1 Primary Metabolites 3.2 Secondary Metabolites 3.2.1Improving Quality by Adjusting Metabolites Through the Regulation of Controlling Environmental Factors References 20 21 27 31 4Hydroponic Systems in Horticulture 35 4.1 4.2 4.3 4.4 4.5 4.6 Drip System Flood and Drain (Ebb and Flow) System Nutrient Film Technique Deep Water Culture Aeroponic System Divergences of Hydroponic Systems References II Controllable Production Factors in Horticulture 36 36 37 38 38 39 40 5Light 43 5.1 5.2 5.3 5.4 5.5 Light Sources in CEH 48 Types of Lamps 48 Major Functions of Light: The Effect of Different Light Qualities on Plant Growth and Development   50 What Happens Under Excess and Lack of Light? 54 Strategies to Increase the Quality of Horticultural Crops by Lighting 54 References 55 6Nutrient Deficiencies 57 6.1 6.2 Nitrogen Deficiency 58 Phosphorus Deficiency 62 X Contents 6.3 6.4 Potassium Deficiency and Other Nutrient Deficiencies 64 Practical Note 65 References 65 7Salt Stress 69 7.1 7.2 7.3 Salt Toxicity Effects Adaptation Strategy to Mitigate Burst of ROS Under Salinity Stress Enriching Bioactive Compounds in Crops by Exposing the Plants to Salt Stress References 71 75 78 79 8Drought Stress 81 8.1 Introduction 8.2 Function of Water in Plants 8.3 What Happens in Plants During Drought Stress? 8.4 Plant Reactions to Drought Stress 8.4.1Adjusting the Osmotic Potential (Ψп) 8.4.2Rise of Antioxidants in Drought-Stressed Plants 8.5 Additional Effects of a Deficient Water Supply 8.6 Methods of Creating a Controlled Water Deficit for Plants References 82 82 83 84 84 85 88 89 93 9Thermal Stress 99 9.1 9.2 9.3 9.4 9.5 9.6 What Is Thermal Stress?
