The movement of water from soil, through plants and into the atmosphere is a complex process that requires and understanding of both biology and physics. In this book, M.B. Kirkham seeks to bring these two disciplines together to create a thorough explanation of the movement of water through plants so that scientists can better address the problem of water availability at the local, regional, and global scale. She explores topics such as the anatomy of plants, pressure chambers, the stress-degree-day concept and much more. Each chapter also includes a short biography on a scientist whose work was covered in the chapter. The second edition contains new information on determining sap flow in plants, dual-probe heat-pulse techniques for monitoring water in the root zone, and celestial time.
