Carotenoid Profiles

Carotenoids are pigment compounds found in cannabis plant tissues, responsible for yellow, orange, and red hues in flowers and leaves. Unlike volatile terpenes, carotenoids are non-aromatic lipophilic molecules that persist through drying and curing. Breeders studying cannabis genetics have identified carotenoid expression as a heritable trait influenced by temperature, light exposure, and genetic background. Carotenoid profiles vary significantly across cultivars and are sometimes correlated with specific lineages. These compounds remain largely understudied in cannabis breeding, though their presence is often documented as a visual marker in strain descriptions and genetic records.

Breeders tracking carotenoid expression use visual phenotype assessment as a selection tool for consistency within a line. Carotenoid accumulation patterns are sometimes stabilized through selective breeding to achieve distinctive aesthetic markers in commercial cultivars.
