The aim of this book is to provide research-focused information regarding selected plant physiology. This book provides fundamental concepts and latest insights on plant physiology covering abiotic stress, plant water relations, mineral nutrition and reproduction. Plant reactions to insufficient water availability and other inorganic strains (like metals) have been studied through changes in water consumption, transport structure and through molecular and genetic methods. A comparatively new feature of fruit nourishment is presented in order to offer the basis for the development of a few fruit quality traits. Compiling researches of experts around the globe, it can serve as a source of methodologies, theories, pathways and ideas for students and researchers in different areas of plant physiology.
