Uv B Reactive Compounds

UV-B reactive compounds refer to secondary metabolites in cannabis that absorb or respond to ultraviolet-B radiation, including certain flavonoids and phenolic compounds. These substances are produced by plants as part of natural stress-response mechanisms when exposed to higher-altitude or intense UV-B environments. In cannabis breeding, lineages originating from high-altitude regions—such as Hindu Kush or certain Tibetan landraces—often carry genetic predisposition toward elevated UV-B compound production. Breeders studying plant resilience and chemical diversity have documented correlations between UV-B reactive metabolites and specific aromatic profiles. These compounds remain an active area of cannabis genetics research for understanding plant adaptation and chemotype variation.

Breeders working with high-altitude or UV-stressed genetics may select for UV-B reactive compound accumulation as a marker of environmental hardiness and genetic stability. Understanding these compounds helps inform preservation strategies for landraces and breeding programs focused on resilience traits.
