Terpene Metabolism

Terpene metabolism refers to the biochemical processes by which cannabis plants synthesize, modify, and degrade terpenes throughout their lifecycle. These pathways involve enzyme-mediated reactions that convert precursor molecules (like geranyl pyrophosphate) into the diverse volatile compounds found in resin glands. Terpene metabolism is influenced by genetics, environmental stress, light exposure, temperature, and developmental stage—factors that breeders and cultivators monitor to influence aromatic and volatile profiles. Understanding these mechanisms helps explain why genetically identical plants can express different terpene ratios under varying conditions. Research into terpene metabolism also informs selective breeding for specific aromatic traits and storage stability.

Breeders leverage terpene metabolism knowledge to select parent plants that produce desired volatile profiles and to identify genetic markers associated with terpene-synthesis pathways. Growers adjust environmental conditions (light spectrum, temperature, humidity, harvest timing) to optimize metabolic activity and terpene accumulation during flowering.
