Oxidation And Terpene Degradation

Oxidation and terpene degradation represent critical chemical processes that alter cannabis flower composition over time. When terpenes—volatile organic compounds responsible for aroma and flavor—encounter oxygen, heat, or light, their molecular structures break down into secondary compounds. This degradation can shift the terpene profile substantially, often reducing volatile terpene content while creating oxidized byproducts. Understanding these mechanisms is essential for breeders, seed banks, and cultivators seeking to preserve genetic expression and maintain stable cannabinoid-terpene ratios across generations. Lineage records frequently note that storage conditions directly influence terpene retention, making preservation protocols a fundamental breeding consideration.

Breeders working in preservation genetics select for chemical stability and oxidation resistance as secondary traits, particularly when developing stable seed lines or cultivar banks. Maintaining accurate terpene profiles across multiple phenotypes requires controlled environmental conditions that slow degradation, allowing breeders to assess true genetic expression rather than degraded or altered
