Seed Development, Dormancy, and Germination Explained | Chapter 21 of Plant Physiology and Development
Seed Development, Dormancy, and Germination Explained | Chapter 21 of Plant Physiology and Development Chapter 21 of Plant Physiology and Development examines how seeds form, enter dormancy, survive desiccation, and eventually resume growth through germination. Seeds are not just passive storage structures; they are highly regulated developmental stages that integrate genetic programs, hormonal signals, and environmental cues. This chapter traces seed development from embryogenesis through dormancy and into germination, emphasizing the roles of hormones such as abscisic acid (ABA), gibberellins (GA), and auxin. For a concise, lecture-style walkthrough of these concepts, watch the Last Minute Lecture summary below.

The mature seed typically contains three main componen...
