Post Harvest Terpene Modification

Post-harvest terpene modification refers to changes in volatile aromatic compounds that occur after flowers are harvested, dried, and cured. Environmental factors—temperature, humidity, light exposure, and air circulation—directly influence which terpenes are retained, oxidized, or transformed during storage and curing. Lineage records frequently report that identical cultivars can develop distinctly different aroma profiles depending on post-harvest handling protocols. This distinction is critical for breeders evaluating true genetic expression versus environmentally-induced aromatic drift. Understanding post-harvest terpene dynamics helps distinguish cultivar characteristics from processing artifacts when assessing breeding lines.

Breeders must account for post-harvest terpene stability when selecting parent plants for consistent aroma traits across generations. Cultivars with robust or volatile terpene profiles require standardized curing protocols to reliably reproduce desired aromatic phenotypes in breeding programs.
