Limonene Production

Limonene is a monocyclic monoterpene commonly found in cannabis varieties, where it contributes citrus-forward aromatic profiles. Limonene biosynthesis in cannabis is controlled by multiple genetic loci and enzymatic pathways that breeders have selectively enhanced over decades of cultivation. Plants expressing high limonene levels often display lemon, lime, or orange-peel aromatic notes, though expression varies with phenotype, growing conditions, and harvest timing. Limonene's presence in terpene profiles is frequently documented in lineages with Citral, Tangie, and Lemon Haze genetics, where citrus aromatic expression became a breeding focus. Understanding limonene-dominant chemotypes helps breeders identify and stabilize aromatic traits across seed lines and cultivar development.

Breeders working in citrus-aroma categories actively select for limonene-dominant phenotypes by monitoring volatile compound expression during flowering and curing stages. High-limonene cuts serve as parent materials in crosses designed to establish consistent terpene profiles in new cultivars.
