Germinable seeds are crucial for the continuity of viability and reproduction in plants. The seed germination mechanism still hides its secrets with its physiological and molecular mysteries. Germination is such a complex event, resulting in different outcomes from species to species, and the same seed lot can show different viability responses when exposed to different ecological conditions. As a matter of fact, in parallel with the efforts of scientists and the development of technology, new methods, models, and applications are being developed to increase germination rates in seed lots. These applications' impact on the viability of plant species varies due to the unique internal structure of each seed at the physiological and molecular levels. Seed germination is so simple that it can be put into a tiny observation, but at the same time, it is so complex that it cannot be explained. This book will aim to explore the morphological, physiological, and molecular aspects of seed germination based on current insights. It will explore seed technology applications linked directly to germination, encompassing research on the physiological and molecular foundations, mechanisms, and adaptations associated with the germination process. We believe this book will offer new perspectives in the presentation of material that will interest researchers, advanced undergraduate students, and others seeking foundational knowledge on seed germination and its intricate mechanisms.
