Storage Degradation

Storage degradation refers to the breakdown of cannabis terpenes and cannabinoids over time due to environmental exposure—primarily light, heat, oxygen, and humidity fluctuations. Terpenes are volatile organic compounds with relatively low boiling points, making them particularly susceptible to oxidation and evaporation during storage. Understanding degradation pathways is essential for breeding programs developing cultivars with robust terpene stability and for seed banks and preservation facilities maintaining genetic integrity. Common degradation products include oxidized terpenes, which can alter both aroma profiles and the broader plant chemistry over extended storage periods. Breeders increasingly focus on lineages known for terpene retention, while seed preservation protocols employ vacuum sealing, cool storage (32-41°F), and low-humidity environments (5-10% relative humidity) to

Breeders working with long-term seed storage and commercial preservation programs select for cultivars with more stable terpene profiles and robust cell structures that resist environmental stress. Understanding which genetic backgrounds show superior terpene retention informs decisions about breeding for shelf stability in commercial and archival contexts.
