Citrus Aroma Compounds

Citrus aroma compounds refer to volatile terpenes and terpenoids commonly associated with lemon, lime, orange, and grapefruit characteristics in cannabis. Limonene is the primary terpene in this classification, though pinene, myrcene, and other minor volatiles contribute to the overall citrus profile. These compounds are produced in the trichome heads of cannabis flowers and are often tagged as desirable markers in breeding programs seeking specific aromatic phenotypes. Citrus-forward strains appear across multiple genetic lineages, including Sativa-dominant and hybrid backgrounds. Preservation of citrus aromas requires careful handling of dried flower and proper storage conditions, as volatile terpenes degrade with heat, light exposure, and time.

Breeders working in the citrus aroma category often select parent plants with elevated limonene and pinene profiles to stabilize citrus phenotypes across generations. Terpene expression varies significantly by phenotype and environmental growing conditions, making sensory profiling during selection a core breeding practice.
