Limonene Myrcene Ratios

Limonene-myrcene ratios describe the relative abundance of these two dominant monoterpenes in cannabis flower, shaping both sensory profile and volatile behavior. Limonene-dominant profiles (limonene > myrcene) typically correlate with citrus aromatics and faster evaporation rates, while myrcene-dominant expressions (myrcene > limonene) are often associated with earthy, herbal notes and slower terpene persistence. These ratios emerge from genetics, cultivation conditions, harvest timing, and post-harvest handling—each variable influencing the final terpene expression. Breeders and researchers track these ratios as a standardized measure of chemotype consistency across generations.

Breeders use limonene-myrcene ratios as a selective marker when stabilizing strain families or creating crosses with predictable aromatic profiles. Terpene ratio stability can indicate genetic homogeneity and reproducibility in seed lines, making it a useful breeding benchmark alongside cannabinoid content.
