Oxidative Terpene Degradation

Oxidative terpene degradation refers to the chemical breakdown of volatile terpenes through exposure to oxygen, light, and heat during cultivation, harvest, drying, and storage. This process can significantly alter the aromatic and chemical profile of cannabis flowers over time, transforming fresh terpene expressions into aged or oxidized profiles. Breeders and cultivators study degradation pathways to understand how initial terpene compositions shift, which influences both preservation strategies and the selection of genotypes with more stable volatile compounds. The oxidation of limonene to carvone, or myrcene breakdown, are examples commonly observed in cannabis genetics documentation. Understanding these degradation mechanisms is essential for seed banking, phenotype stability assessment, and breeding programs focused on terpene retention.

Breeders working with terpene-forward selections increasingly evaluate oxidative stability as a phenotypic trait, seeking genetic backgrounds that maintain volatile profiles longer during storage and cure. This knowledge informs decisions about which parent lines produce more durable terpene expressions and how environmental control during production affects the final product's aromatic consistenc
