This book offers an up-to-date account of important crops grown worldwide. It provides detailed discussion on the history of plant exploration, migration, domestication and distribution, and crop improvement. The text starts with the origin and diversification of cultivated plants, followed by discussion on tropical, subtropical and temperate crops that are sources of food, beverages, spices and medicines, as well as plant insecticides, timber plants and essential oil-yielding plants. The genetic and evolutionary aspects of different plants and their health benefits are highlighted. The book covers topics dealing with biodiversity conservation, petro-crops, ethnobotanical studies, and important sub-tropical and temperate plants that have commercial importance. The significance of major plant species under each category is described in detail. Illustrated with numerous well-labelled line diagrams and pictures, this book will be useful for students of botany, food and nutrition, forestry
This thoroughly revised and updated edition provides an accessible overview of the rapidly advancing field of plant physiology. Key topics covered include absorption of water, ascent of sap, transpiration, mineral nutrition, fat metabolism, enzymes and plant hormones. Separate chapters are included on photosynthesis, respiration and nitrogen metabolism, and emphasis is placed on their contribution to food security, climate resilient farming (or climate-smart agriculture) and sustainable development. There is also a chapter on the seminal contributions of plant physiologists. Supported by the inclusion of laboratory experimental exercises and solved numerical problems, the text emphasises the conceptual framework, for example, in coverage of topics such as thermodynamics, water potential gradients and energy transformation during metabolic processes, water use efficiency (WUE) and nitrogen use efficiency (NUE). Bringing together the theoretical and practical details, this text is access
