In this comprehensive and stimulating text and reference, the authors have succeeded in combining experimental data with current hypotheses and theories to explain the complex physiological functions of plants. For every student, teacher and researcher in the plant sciences it offers a solid basis for an in-depth understanding of the entire subject area, underpinning up-to-date research in plant physiology. The authors vividly explain current research by references to experiments, they cite original literature in figures and tables, and, at the end of each chapter, list recent references that are relevant for a deeper analysis of the topic. In addition, an abundance of detailed and informative illustrations complement the text.In this comprehensive and stimulating text and reference, the authors have succeeded in combining experimental data with current hypotheses and theories to explain the complex physiological functions of plants.
