Seed Dormancy Mechanisms

Seed dormancy mechanisms are physiological and environmental conditions that delay germination until optimal growing circumstances arrive. Cannabis seeds exhibit varying dormancy depths depending on genetics and storage conditions—some cultivars germinate readily while others require specific environmental triggers like temperature fluctuation, moisture exposure, or aging. Breeders studying these mechanisms investigate how dormancy traits affect seed viability across seasons and storage timelines. Understanding dormancy patterns is essential for seed banks, breeding programs, and preservation efforts seeking to maintain genetic stability. Modern cannabis genetics show diverse dormancy profiles, reflecting both wild-type ancestry and selective breeding for rapid, uniform germination in controlled environments.

Breeders working with dormancy mechanisms often select for either rapid germination (commercial seed production) or robust dormancy (preservation and long-term storage viability). Dormancy depth is a heritable trait that influences seed catalog design and breeding timelines.
