Myrcene Thermosensitivity

Myrcene thermosensitivity describes genetic variation in how cannabis plants express myrcene terpene levels in response to temperature fluctuations during cultivation. Myrcene is one of the most abundant terpenes in cannabis and is commonly associated with earthy, herbal, and clove-like aromatic profiles. Plants within this family often show increased myrcene expression in cooler growing conditions, while warmer environments may favor alternative terpene pathways. This trait is influenced by multiple genetic loci and environmental factors, making it a complex characteristic for breeding programs. Understanding myrcene thermosensitivity helps breeders predict and stabilize aromatic profiles across different cultivation climates and seasons.

Breeders working with myrcene-dominant cultivars often select for thermosensitive lines to develop genetics suited to specific regional growing conditions or to create consistent terpene expression year-round. This trait allows cultivators to influence final aromatic composition through temperature management during flowering and drying phases.
