Dormancy And Stratification

Dormancy and stratification are seed-stage physiological processes rather than aromas, but they're critical traits in cannabis breeding and seed preservation. Dormancy refers to a seed's temporary state of metabolic inactivity, while stratification—exposure to cold, moisture, and sometimes light cycles—can break dormancy and trigger germination. Breeders and seed banks track these traits because they affect germination rates, storage viability, and predictability in cultivation. Seeds exhibiting strong dormancy often show improved longevity in storage, whereas those requiring stratification may need controlled pre-treatment protocols. Understanding these mechanisms helps preserve genetic material and optimize breeding timelines.

Breeders select for or against dormancy depending on cultivation goals: rapid, synchronized germination favors minimal dormancy, while preservation-focused breeding values strong dormancy for extended seed viability. Stratification requirements are often mapped during variety development to standardize nursery protocols and improve yield predictability across growing seasons.
