Terpene Synthesis Timing

Terpene synthesis timing refers to when cannabis plants produce and accumulate volatile aromatic compounds throughout their life cycle. These production patterns typically begin during vegetative growth but intensify significantly during flowering, with peak volatile concentrations often occurring in the final weeks before harvest. Different cultivars show distinct timing profiles—some accumulate terpenes early and plateau, while others demonstrate progressive increases through late flower. Understanding synthesis timing is crucial for breeders selecting for stable aroma expression, as environmental factors like light cycles, temperature fluctuations, and nutrient availability can shift when and how much volatile production occurs. Lineage records frequently report that certain parent genetics reliably reproduce early or late terpene-peak phenotypes, making timing a heritable trait worth

Breeders working in aroma genetics use terpene synthesis timing as a selection criterion to establish predictable harvest windows and consistent aromatic profiles across generations. Stabilizing this trait helps ensure that offspring reliably reach target volatile concentrations at consistent developmental stages, reducing crop-to-crop variability.
