Uv Protection

UV protection in cannabis plants refers to the natural mechanisms by which certain cultivars resist ultraviolet radiation damage, often involving elevated levels of flavonoids and other secondary metabolites. These compounds, including cannabichromene (CBC) precursors and terpenes like pinene, accumulate in response to UV-B exposure and may concentrate in trichomes. Plants from high-altitude or equatorial breeding lines frequently exhibit these traits due to historical environmental pressure. UV-protective phenotypes are of particular interest to breeders developing cultivars for outdoor cultivation in intense sunlight regions. Lineage records commonly associate this trait with Landrace and high-altitude genetics from the Andes, Hindu Kush, and East African regions.

Breeders working to improve outdoor resilience and light-stress tolerance often select for UV-protective traits when establishing parent lines. Crosses between UV-adapted landrace genetics and modern cultivars help develop cultivars better suited to full-sun outdoor and greenhouse environments.
