Dormancy Period

Dormancy period refers to the natural resting phase seeds enter after maturation, during which germination is suppressed even under favorable conditions. This trait is controlled by genetic and environmental factors, including seed coat impermeability, hormone balance, and light/temperature sensitivity. Wild cannabis populations exhibit dormancy as an evolutionary adaptation—seeds delay sprouting to avoid unfavorable seasons and spread germination across time. Modern cultivation often selects against strong dormancy for faster, more uniform crop cycles, though some breeding lines maintain dormancy traits for preservation or specific agricultural contexts. Understanding dormancy mechanics helps breeders optimize seed viability storage, predict germination timing, and maintain genetic diversity in seed banks.

Breeders manipulate dormancy through selection and cross-breeding to achieve desired germination windows. Shorter dormancy periods support commercial production efficiency, while retained dormancy traits support seed longevity in storage and heritage preservation programs.
