Uv Induced Terpenes

UV-induced terpenes refer to volatile compounds that cannabis plants synthesize in response to ultraviolet (UV) light exposure, particularly UV-B wavelengths. Research suggests that UV stress triggers secondary metabolite production, including certain monoterpenes and sesquiterpenes, as a potential photoprotective mechanism. This phenomenon has attracted breeding and cultivation interest, as some cultivators report altered terpene profiles under controlled UV-B supplementation. The specific compounds produced and their concentrations vary significantly based on plant genetics, exposure duration, intensity, and growth stage. Understanding these photochemical pathways may inform cultivation strategies for breeders seeking to develop or emphasize particular aromatic profiles.

Breeders studying UV-responsive genetics explore how different lineages express terpene diversity under light stress conditions, potentially identifying cultivars with naturally robust secondary metabolite production. This knowledge supports development of cultivation protocols and selection of parents with desired aromatic characteristics.
