Water Relations of Plants is intended for the students who have very limited knowledge about plant water relations and those who need a systematic presentation of the fundamental concepts and related methods of plant water relation without any unnecessary details which often cause distraction. The authors have attempted to cover all aspects of the subject. This, we hope, will make the reading of this topic, which is often considered relatively more terse and dry among the topics in plant physiology, more interesting. The book will also be useful and insightful for research scholars and teachers working in the area of plant water relations.
