Temperature Dependent Terpenogenesis

Temperature-dependent terpenogenesis describes the environmentally-driven variation in terpene expression across different growing conditions. Research in cannabis cultivation has documented that volatile compound profiles can shift measurably between warm and cool growing phases, with some cultivars expressing different dominant terpenes under different thermal regimes. This phenomenon is not unique to cannabis—it occurs widely across aromatic plants—and reflects the dynamic biosynthetic adjustments plants make in response to ambient conditions. Breeders and cultivators track these shifts to understand which genetic lines maintain stable terpene profiles versus those prone to thermal drift. Understanding this trait is essential for consistent phenotype expression and for selecting germplasm suited to specific growing environments.

Breeders working in controlled-environment agriculture prioritize stability testing across temperature ranges to identify cultivars with robust, consistent aroma profiles. Lines exhibiting pronounced temperature-dependent terpenogenesis may be useful for studying terpene biosynthesis mechanisms or for targeted breeding toward specific thermal niches.
