Secondary Metabolite Synthesis

Secondary metabolite synthesis refers to the biochemical processes through which cannabis plants produce compounds beyond primary growth requirements—including cannabinoids, terpenes, and flavonoids. These pathways are primarily activated during flowering and are shaped by genetics, environmental stress, light spectrum, and nutrient availability. Breeders and cultivation researchers study secondary metabolite production to understand how different genetic lines accumulate distinct chemical profiles. The genetic expression of enzymes controlling these pathways varies significantly across cultivars, making secondary metabolite synthesis a key target in selective breeding programs. Understanding these biosynthetic routes helps contextualize why chemically similar strains may develop different aromatic and cannabinoid profiles under identical conditions.

Breeders select parent plants with robust secondary metabolite synthesis to stabilize desirable terpene and cannabinoid expression across generations. Cultivators manipulating light, temperature, and nutrient ratios during flower rely on the plant's inherent biosynthetic capacity—a trait heavily influenced by maternal and paternal genetics.
