Phenolic Development

Phenolic development refers to the biosynthetic accumulation of phenolic compounds—including flavonoids, phenolic acids, and tannins—during cannabis plant growth and maturation. These secondary metabolites develop progressively through vegetative and flowering stages, with concentrations often increasing as flowers mature. Phenolic profiles vary significantly across cultivars and are influenced by genetics, light exposure, nutrient availability, and stress conditions. Understanding phenolic development is relevant to breeders selecting for specific chemical compositions and researchers studying plant chemistry. Unlike cannabinoids or terpenes, phenolic compounds receive less commercial attention but contribute to plant structure, UV protection, and overall phytochemical diversity.

Breeders working with phenolic development typically assess late-flowering maturity, stress resilience, and secondary metabolite density when selecting parent plants. Stable phenolic accumulation patterns can serve as markers for predictable chemical profiles across growing environments and generation cycles.
