Seed physiology is fundamental to agriculture and horticultural production, plant science and biodiversity. Knowledge of seed development, maturation, dormancy, storage and germination is essential to enable successful plant reproduction. Seed Physiology is a unified textbook designed to bridge foundational seed biology with advanced molecular and applied aspects of seed science. It covers topics from classical concepts such as seed development, dormancy and germination to advanced-level physiological, biochemical, and molecular mechanisms. Key features:· Full coverage of seed biology, dormancy, germination, hormonal and environmental regulation, epigenetics, ROS signaling, mitochondrial activation, and omics.· Integration of theory with applied sections: commercial seed production, seed quality, enhancement technologies, biotechnology, and seed storage.· Rich pedagogical tools: diagrams, tables, laboratory protocols, end-of-chapter review questions, and instructor resources for teaching. The book is suitable for both undergraduate and graduate courses in seed physiology and related fields as well as researchers in plant sciences, agronomy and horticulture, and those in the seed industry.
