Seed Dormancy

Seed dormancy is a physiological state where viable cannabis seeds remain metabolically inactive until environmental conditions trigger germination. This trait is not a terpene but rather a genetic and biochemical mechanism involving seed coat impermeability, hormone signaling (particularly abscisic acid), and developmental checkpoints. Breeders working with photoperiod and autoflowering genetics must understand dormancy patterns, as they affect seed viability storage, germination timing, and breeding program consistency. Dormancy duration varies widely across strain families and seed types, influencing how seeds respond to temperature, light, and moisture cues. Understanding dormancy is critical for seed preservation protocols and for developing cultivars suited to specific cultivation environments.

Breeders select for predictable germination behavior by either extending or reducing dormancy periods depending on intended market and growing conditions. Seed dormancy traits are particularly relevant in developing stable F1 hybrids and landrace-derived lines where consistent emergence timing impacts large-scale production.
