Late Cycle Terpenes

Late cycle terpenes are volatile aromatic compounds that accumulate in cannabis flowers predominantly during the final weeks of flowering, after the initial terpene expression phase. These secondary terpene profiles often differ chemically and aromatically from early-cycle volatile production, reflecting shifts in plant metabolism as seed maturation or senescence approaches. Breeders and cultivators observe these shifts through changes in aroma intensity, complexity, and specific compound ratios. Documentation of late-cycle terpene expression helps characterize strain stability and predict harvest-window flavor profiles. Understanding this temporal aspect of terpene development is relevant for breeding programs focused on consistent aromatic expression across crop cycles.

Breeders working with late-cycle terpene expression use this trait to identify lines with stable, persistent aromatic profiles through full maturation. Selecting parent plants that maintain or enhance secondary terpene accumulation supports the development of cultivars with reproducible sensory characteristics at target harvest windows.
