Potato Physiology provides perspective and knowledge on the biological behavior and potentials of the potato plant. Organized into 15 chapters, this book focuses on tuber development physiology, biochemistry, and anatomy. This text also covers topics on physiological and biochemical aspects of photosynthesis, photoassimilate partitioning, respiration, tuberization, as well as carbohydrate and protein metabolisms. It elucidates potato's rest period, the stage when growth is inhibited as a result of endogenous causes, and the tubers' disorders, environmental responses, frost hardiness, and tissue culture. This text provides a worldwide perspective and is organized and presented to be useful to graduate students, teachers, and potato investigators.
