Uv Exposure And Secondary Metabolites

UV exposure triggers the production of secondary metabolites in cannabis plants, including flavonoids, phenolic compounds, and certain terpenes that serve as natural photoprotectants. Breeders and cultivators have documented that controlled UV-B light during flowering can influence resin composition and volatile organic compound profiles. This relationship between light stress and chemical expression is of particular interest in breeding programs focused on terpene diversity and phytochemical complexity. The mechanism involves plant stress response pathways that upregulate synthesis of compounds typically associated with plant defense. Understanding these dynamics helps contextualize how environmental conditions during cultivation interact with underlying genetic potential.

Breeders working in photochemistry-focused lines study UV exposure as a non-genetic lever for expressing latent chemical phenotypes. Documenting how specific genetics respond to controlled UV stress helps identify cultivars with robust secondary metabolite production under varied growing conditions.
