Plant Physiology: A Treatise, Volume IX: Water and Solutes in Plants explores problems associated with water and solutes of plants as they grow. This book considers water relations of plant cells, along with transpiration and water balance, the physiology of stomata, ion uptake by roots from the soil, and salt relations of plants. This volume is organized into seven chapters and begins with an introduction to the water potential terminology used by plant physiologists in describing the water relations of plant communities, individual plants and their organs, and plant cells. An account of the elastic properties and hydraulic conductivity of plant cell walls is provided. The following chapters focus on the soil-plant-atmosphere continuum, water uptake and movement through plants, the effects of water deficit on plant development and other processes, and the mechanics of stomatal functioning. The book also introduces the reader to salt relations of plant cells, tissues, and roots as well as long-distance transport in the phloem, and then concludes by discussing the solute composition of cells during development. This book is a valuable resource for teachers, research workers, and students with specific interest in plant physiology.
