Aroma Degradation Factors

Aroma degradation factors are environmental and storage conditions that diminish or alter the volatile terpene profiles in cannabis flowers over time. Common degradation pathways include oxidation from light and oxygen exposure, thermal breakdown from heat, moisture-induced microbial activity, and volatilization from inadequate sealing. Understanding these factors is essential for breeders selecting for stable, long-lasting aromatic expression in stable lines, as well as for preserving genetic material in seed banks and live collections. Storage protocols that minimize light, temperature fluctuation, and oxygen contact are foundational to maintaining the aromatic integrity of cultivars across generations.

Breeders working with aromatic stability evaluate how parental lines retain terpene expression under standard storage conditions, selecting for genetic backgrounds that produce resilient, non-volatile essential oil profiles. Strains bred for commercial or archival purposes often incorporate traits associated with lower degradation rates, ensuring consistent sensory and chemical profiles across har
