Flavonoid Production

Flavonoids are a diverse class of plant compounds responsible for pigmentation, UV protection, and aromatic qualities in cannabis. These polyphenolic molecules contribute to the plant's color expression—from deep purples and blues to reds and yellows—and are often correlated with specific terpene profiles. Flavonoid production is influenced by genetics, light exposure, and growing conditions, making it a trait of interest to breeders seeking distinctive phenotypes. Major cannabis flavonoids include cannflavin A, cannflavin B, and quercetin, though comprehensive flavonoid mapping in cannabis remains an active area of research. Understanding flavonoid expression helps breeders predict color stability and aroma complexity across generations.

Breeders working in ornamental and specialty markets actively select for flavonoid-rich phenotypes to establish consistent color expression. Flavonoid profiles are sometimes used as markers for identifying stable cultivars, since production patterns can indicate genetic stability and environmental responsiveness.
