Terpene Thermosensitivity

Terpene thermosensitivity refers to the temperature-dependent volatility and stability of cannabis terpenes during growth, drying, and storage. Different terpenes have distinct boiling points and degradation thresholds; limonene and pinene are often classified as more volatile, while myrcene and caryophyllene show different thermal profiles. Environmental temperature fluctuations during cultivation can influence both terpene accumulation and ratios within developing plants. Post-harvest handling—particularly drying temperature and storage conditions—significantly impacts which terpenes are preserved or lost. Understanding thermosensitivity is central to breeding programs focused on terpene stability and phenotype consistency across seasons.

Breeders working with terpene profiles increasingly consider thermosensitivity when selecting parent genetics and optimizing cultivation protocols. Lines exhibiting heat-stable terpene expression or predictable terpene retention across temperature ranges are valued for commercial consistency and batch-to-batch reliability.
