Uv Induced Compounds

UV-induced compounds refer to secondary metabolites that cannabis plants synthesize in response to ultraviolet light exposure, particularly UV-B radiation. These include flavonoids, phenolic acids, and certain terpene precursors that accumulate in trichomes and leaf tissue as a protective mechanism. Breeders and researchers have documented variable responses across cultivars, with some genetic lines showing stronger upregulation of these compounds than others under controlled UV conditions. The relationship between UV stress and cannabinoid or terpene expression remains an area of active study in cannabis genetics. Understanding UV-responsive traits helps inform cultivation protocols and breeding selection for desired metabolite profiles.

Breeders selecting for UV-responsive phenotypes may use controlled light exposure during trials to identify lines that accumulate higher levels of protective compounds. This trait is relevant for cultivators optimizing light spectrum and intensity strategies, though inheritance patterns of UV-sensitivity remain poorly mapped in formal breeding literature.
