Plant Physiology: A Treatise, Volume VIA: Physiology of Development: Plants and Their Reproduction explores the various problems of development and reproduction that arise as plants, responsive to environmental stimuli, develop a vegetative plant body and produce seeds and fruits or organs of perennation. This book considers the morphological aspects of plant growth and development as well as the growth and reproduction of fungi, physiological aspects of vegetative reproduction and flowering, and perennation and dormancy. This volume is organized into four chapters and begins with an overview of growth and development, with reference to organization and patterns of development in vascular plants and the initiation and development of plants. The discussion then shifts to vegetative, sexual, and asexual reproduction in fungi, along with heterokaryosis and morphogenesis. The next chapter explores reproduction in plant biology, focusing on vegetative and sexual reproduction, sex determination, and photoperiodism. This book concludes by considering the physiological mechanisms underlying the production of organs of perennation and the establishment of dormancy. This text will be of value both to graduate students and to established investigators with specific interest in plant physiology.
