Chemical Degradation

Chemical degradation in cannabis refers to the breakdown of cannabinoids, terpenes, and other volatile compounds over time, typically triggered by exposure to heat, light, oxygen, and humidity. This process is central to post-harvest handling, storage, and curing practices in breeding programs and seed preservation. Breeders and seed banks monitor degradation rates to understand strain stability, shelf life, and phenotypic consistency across generations. Different genetic lines show varying resistance to oxidative stress and compound breakdown, making degradation patterns a measurable trait in cultivar documentation. Proper storage protocols—including temperature control, light exclusion, and moisture management—are essential practices for maintaining genetic integrity in seed banks and breeding populations.

Breeders assess chemical degradation rates to evaluate cultivar longevity and genetic stability. Strains bred for seed storage resilience or used in long-term conservation programs are often screened for slow degradation profiles.
