Seed Dormancy

Seed dormancy is a physiological state in which viable cannabis seeds remain inactive until environmental conditions trigger germination. This trait is genetically influenced and commonly observed across landrace and heirloom genetics, where dormancy periods historically improved survival rates in variable climates. Breeders working with seed production document dormancy as a heritable characteristic that can persist for months or years if seeds are stored in cool, dry conditions. Understanding dormancy patterns is essential for seed banks and cultivation operations managing inventory and germination scheduling. Modern cultivars exhibit varying dormancy profiles depending on their genetic background and environmental history.

Breeders select for or against dormancy traits depending on production goals. Shorter dormancy cycles are preferred in commercial seed operations for faster germination protocols, while longer dormancy may be retained in conservation breeding to preserve genetic stability and extend seed viability.
