Carotenoid Expression
Carotenoid expression refers to the visible accumulation of carotenoid pigments—yellows, oranges, and reds—in cannabis plant tissues, particularly leaves and flowers. These pigments are fat-soluble compounds that often intensify under cool temperatures, UV stress, or genetic predisposition. Carotenoid-heavy phenotypes are commonly documented in landraces and modern cultivars bred for visual distinction. The pigmentation is structurally distinct from anthocyanins (purples/blues) and chlorophyll (greens), though plants may express multiple pigment types simultaneously. Breeders have long tracked carotenoid expression as a stable morphological marker for phenotype documentation and seed line differentiation.

Breeders working in heirloom and boutique seed lines often select for carotenoid-rich phenotypes as visual identifiers and to maintain genetic markers across generations. Carotenoid expression is heritable and relatively stable across growing environments, making it useful for phenotype stabilization in F2+ populations.
