Description

Shedding of Plant Parts focuses on the anatomical, physiological, and ecological features of shedding of vegetative and reproductive parts of plants. This book encompasses both natural and induced shedding. Organized into 12 chapters, this book first outlines the extent of shedding of plant cells, tissues, and organs and summarizes the biological and economic implications of such shedding. Separate chapters follow that discuss anatomical and histochemical changes in leaf abscission; the physiological ecology and internal regulation of abscission; and the shedding of shoots, branches, bark, roots, pollen, seeds, and reproductive structures of forest trees. This book also explains the anatomical changes in abscission of reproductive structures, chemical thinning of flowers and fruits, and chemical control of fruit abscission. This book will be valuable to plant anatomists, pathologists, and physiologists, and to agronomists, arborists, biochemists, ecologists, entomologists, foresters, horticulturists, landscape architects, meteorologists, and soil scientists.
