Polyphenol Metabolism

Polyphenol metabolism refers to how cannabis plants synthesize and accumulate phenolic compounds—including flavonoids, stilbenes, and phenolic acids—through enzymatic pathways. These secondary metabolites accumulate in flowers, leaves, and trichomes and are often associated with color expression, oxidative stress response, and organoleptic profiles. Polyphenol production is influenced by genetics, cultivation conditions, light exposure, and plant maturity. Lineage records frequently report variation in polyphenol accumulation across different cultivars and chemotypes. Understanding polyphenol metabolism is relevant to breeders selecting for specific color phenotypes, resilience traits, and chemical diversity.

Breeders working in this category often select parent plants showing distinct polyphenol accumulation patterns—such as deep purple or blue coloration—to stabilize these traits in offspring. Knowledge of polyphenol pathways helps breeders predict how environmental stress, photoperiod, and genetic background influence final plant appearance and secondary metabolite profiles.
