Volatile Organic Compound Synthesis

Volatile organic compounds (VOCs) are small-molecular organic molecules that readily evaporate at room temperature, forming the aromatic signature of cannabis flowers. In cannabis, VOCs—primarily terpenes and sesquiterpenes—are synthesized in trichromatic glands on flowers and leaves through enzymatic pathways controlled by plant genetics. These compounds serve ecological functions in wild plant populations and accumulate during late-stage flower development. VOC synthesis is influenced by environmental factors including light, temperature, and soil composition, but genetic potential for compound production remains heritable. Understanding VOC synthesis patterns helps breeders select for desired aromatic profiles and provides a framework for studying cannabinoid-terpene interactions.

Breeders select parent plants based on VOC profiles to establish consistent aromatic lineages. Monitoring terpene production across generations allows for stabilization of volatile compound ratios in F1 hybrids and inbred lines.
