Terpene Chemistry Overview

Terpenes are volatile organic compounds produced by cannabis plants that contribute to aroma, flavor, and other plant characteristics. Over 150 identified terpenes have been documented in cannabis, each with distinct molecular structures and boiling points that influence how they vaporize and interact during plant growth, storage, and consumption. Major terpenes include limonene, myrcene, pinene, caryophyllene, and linalool, though minor terpenes also play roles in the plant's total chemical profile. Terpene expression varies significantly across cultivars and environmental conditions, making them useful markers for strain identification and breeding selection. Understanding terpene chemistry is central to cannabis genetics work, as it connects plant lineage, phenotype expression, and preservation protocols.

Breeders monitor terpene profiles to maintain strain identity across generations and to select parent plants with desired aromatic characteristics. Terpene stability under storage and cultivation conditions is a practical breeding consideration for commercial seed production and long-term germplasm preservation.
