Uv B Response

UV-B response refers to the plant's biochemical adaptation to ultraviolet-B radiation exposure, which can trigger increased production of secondary metabolites including certain cannabinoids and terpenes. This phenomenon is not an aroma itself, but rather a cultivation variable that influences volatile compound expression. Breeders and cultivators have observed that controlled UV-B stress conditions may alter the aromatic and chemical profiles of cannabis plants. The relationship between UV-B exposure and terpene/cannabinoid synthesis remains an active area of horticultural research. Different genotypes show varying degrees of stress-induced metabolite upregulation. Understanding this mechanism is relevant for controlled environment agriculture and trait selection.

Breeders working in controlled environment systems study UV-B response as a phenotypic marker for stress tolerance and secondary metabolite synthesis. Selecting plants that upregulate desirable compounds under controlled UV-B stress may support development of more chemically robust cultivars.
