Antioxidant Phenotypes

Antioxidant phenotypes refer to cannabis plants exhibiting elevated levels of compounds like flavonoids, polyphenols, and carotenoids—molecules that function as oxidative stress reducers in plant tissue. These traits are typically expressed across multiple plant families and are influenced by genetics, growing conditions, and harvest timing. Breeders working in this category often select for visual markers such as deep purple, blue, or red pigmentation, which frequently correlate with higher anthocyanin content. Antioxidant-rich phenotypes have become an area of interest in breeding programs seeking to document the full phytochemical profile of cannabis germplasm. Understanding these phenotypes requires analysis beyond cannabinoid and terpene profiles, including chromatography and spectrometry methods. Selection for antioxidant expression remains largely phenotypic and environmental rath

Breeders document antioxidant phenotypes to map genetic diversity and preserve lineages with distinctive phytochemical signatures. These traits serve as research markers for understanding cannabis biochemistry and germplasm conservation efforts.
