Polyphenol Traits

Polyphenol traits refer to the genetic expression of polyphenolic compounds in cannabis—a diverse class of plant metabolites including flavonoids, phenolic acids, and other oxidized aromatic compounds. These compounds accumulate in flowers, leaves, and trichomes and are often associated with plant stress responses, UV protection, and oxidative stability during storage and processing. Polyphenol expression varies significantly across cultivars and is influenced by both genotype and environmental factors like light exposure and temperature. Breeders studying polyphenol traits typically assess them through laboratory analysis rather than sensory evaluation alone. Understanding polyphenol genetics is relevant to preservation, shelf stability, and the chemical stability of extracted products.

Breeders working in preservation and product stability increasingly select for polyphenol-rich lineages, as these compounds contribute to antioxidant capacity and resistance to degradation over time. Lines expressing higher polyphenol content may retain cannabinoid and terpene profiles more effectively during storage and processing, making them valuable for seed-stock development.
