Photodegradation Sensitivity

Photodegradation sensitivity refers to the tendency of cannabinoids and terpenes to degrade when exposed to light, particularly UV and visible wavelengths. Cannabis plants and dried material vary in their susceptibility to this process, influenced by genetics, pigmentation, and secondary metabolite composition. Strains with higher anthocyanin or carotenoid content often show different photostability profiles than those with minimal pigmentation. This trait is primarily relevant to seed storage, breeding stock preservation, and post-harvest handling protocols. Understanding photodegradation sensitivity helps breeders and cultivators design appropriate storage conditions and predict cannabinoid profile stability over time.

Breeders working with long-term seed banks and preservation programs monitor photodegradation sensitivity to maintain genetic integrity across generations. Selection for robust secondary metabolite stability under light exposure is relevant when developing cultivars intended for extended storage or seed longevity.
