Secondary Metabolite Profile

Secondary metabolites are organic compounds produced by cannabis plants beyond primary growth and reproduction—including cannabinoids, terpenes, flavonoids, and phenolic compounds. These compounds develop through complex enzymatic pathways influenced by genetics, environment, and developmental stage, and represent the chemical diversity breeders observe across cultivars. Lineage records frequently report distinct secondary metabolite signatures inherited through parent plants, though expression varies significantly with growing conditions, harvest timing, and post-harvest handling. Understanding secondary metabolite profiles is foundational to cannabis genetics work, as these compounds determine sensory characteristics, chemical composition, and commercial categorization of seed lines.

Breeders select parent plants based on secondary metabolite composition—targeting specific terpene ratios, cannabinoid type distributions, or flavonoid expression—to stabilize desired profiles across generations. Phenotyping secondary metabolites through analytical methods helps breeders identify and preserve chemically distinct lines within families.
