Terpene Ontogeny

Terpene ontogeny refers to the developmental pathway and timeline by which terpenes accumulate and differentiate in cannabis plant tissues during growth. Unlike static terpene profiles, ontogeny examines how volatile compound expression changes from seedling through flowering, influenced by genetics, light exposure, nutrient availability, and environmental stress. Early-stage plants often express lighter, more volatile terpenes, while mature flower typically shows increased heavier monoterpenes and sesquiterpenes. Understanding ontogeny helps breeders and cultivators identify critical windows for phenotype expression and predict mature terpene profiles. This field remains understudied relative to cannabinoid ontogeny, but lineage records increasingly document strain-specific terpene progression patterns.

Breeders use ontogeny mapping to select parents that express desirable terpene profiles consistently across generations and growing conditions. Cultivators working with specific lineages often track terpene development timing to optimize harvest scheduling and identify phenotypes early in the plant lifecycle.
