Limonene

Limonene is a monocyclic monoterpene commonly found across the cannabis genome, particularly prominent in citrus-forward chemotypes. It comprises part of the volatile aromatic profile in many cultivars, often co-expressing alongside pinene, myrcene, and other terpenes. Limonene's prevalence in cannabis breeding suggests selection for certain flavor and aroma characteristics, though terpene expression varies significantly based on cultivation conditions, harvest timing, and plant genetics. Breeders working in this category frequently track limonene levels when developing strains marketed toward citrus or bright-note sensory profiles. The compound's stability and volatility during drying and storage make it a notable consideration in preservation protocols.

Cannabis breeders often identify and select for limonene-dominant phenotypes when pursuing citrus aroma objectives. Limonene's interaction with other terpenes in the total volatile profile influences the final bouquet, making it a tracked marker in strain development and chemotype classification.
