Flavonoid Expression

Flavonoid expression refers to the biosynthetic production and accumulation of flavonoid compounds in cannabis plant tissues, including leaves, flowers, and trichomes. These polyphenolic molecules contribute to plant pigmentation, UV protection, and structural integrity during development. Flavonoid profiles vary significantly across cultivars and are influenced by genetics, light exposure, temperature, and nutrient availability. While flavonoids are distinct from volatile terpenes, they often co-occur in cannabis and may influence overall plant chemistry and phenotype expression. Breeders and cultivators interested in comprehensive cannabinoid and secondary metabolite profiling increasingly measure flavonoid composition as part of strain characterization.

Breeders working on phenotype stability and environmental resilience often select for robust flavonoid expression, as these compounds support plant stress tolerance and structural development. Flavonoid profiles are occasionally used as markers for cultivar authentication and lineage verification in breeding programs.
