Uv B Responsive Compounds

UV-B responsive compounds are secondary metabolites that plants synthesize in response to ultraviolet-B light exposure. In cannabis cultivation, these include flavonoids, phenolic acids, and certain terpene precursors that increase under controlled UV-B supplementation. Breeders and cultivators study these compounds because they're genetically regulated traits—some cultivars show stronger UV-B response than others. The underlying genetics determining UV-B sensitivity remain an active area of cannabis breeding research. Understanding this mechanism helps breeders select for cultivars with stable secondary metabolite production across varying light conditions.

Breeders working with photoperiod control and light spectrum optimization track UV-B responsiveness as a heritable trait. Selecting parent plants that consistently upregulate protective compounds under UV stress may improve cultivar resilience and metabolite expression in diverse growing environments.
