Uv Induced Volatiles

UV-induced volatiles are secondary metabolites produced by cannabis plants in response to ultraviolet-B (UVB) radiation exposure during growth. These compounds are distinct from baseline terpene profiles and emerge as photoprotective mechanisms rather than constitutive aromatics. Breeders and cultivators working with controlled lighting systems have documented shifts in volatile profiles when UVB supplementation is applied, particularly in the final flowering stages. This phenomenon is of interest to genetics researchers studying environmental phenotype expression and terpene plasticity. Understanding UV-induced volatile production helps differentiate between genetic terpene expression and environmentally-triggered secondary metabolism, which is relevant for standardized breeding protocols.

Plant breeders use UV exposure protocols during trials to assess a cultivar's capacity to produce stress-response volatiles, which may correlate with overall plant resilience. Documenting these induced profiles helps distinguish truly high-terpene genetics from plants that simply respond dramatically to environmental triggers.
