Water Relations of Plants and Soils, successor to the seminal 1983 book by Paul Kramer, covers the entire field of water relations using current concepts and consistent terminology. Emphasis is on the interdependence of processes, including rate of water absorption, rate of transpiration, resistance to water flow into roots, soil factors affecting water availability. New trends in the field, such as the consideration of roots (rather than leaves) as the primary sensors of water stress, are examined in detail.Addresses the role of water in the whole range of plant activitiesDescribes molecular mechanisms of water action in the context of whole plantsSynthesizes recent scientific findingsRelates current concepts to agriculture and ecologyProvides a summary of methods
