Oxidative Aging

Oxidative aging refers to chemical changes in cannabis plant material over time when exposed to oxygen, light, and heat. During storage or curing, cannabinoids and terpenes undergo oxidation—a process where molecular structures break down or transform into secondary compounds. Breeders and seed banks monitor oxidative processes because they affect cannabinoid profiles and aromatic stability across generations. This aging mechanism is particularly relevant when evaluating long-term seed viability and phenotype expression in breeding programs. Understanding oxidation rates helps inform proper storage protocols and predict how cultivars will perform across different preservation conditions.

Breeders studying oxidative stability assess how parent lines maintain cannabinoid integrity over time, which influences seed longevity and phenotype consistency in subsequent generations. Seed banks prioritize low-oxygen storage environments to slow oxidation and preserve genetic expression accuracy.
