Post Harvest Metabolism

Post-harvest metabolism refers to the biochemical processes that continue in cannabis flower and trim after harvest, including chlorophyll breakdown, terpene volatilization, and cannabinoid decarboxylation. These metabolic shifts are influenced by drying temperature, humidity, light exposure, and storage conditions, and directly affect final plant chemistry and aroma profile. Breeders and cultivators track post-harvest metabolism because different cultivars show varying rates of enzymatic activity during the curing window. Understanding these processes is foundational to seed development work, as lineages with stable post-harvest profiles tend to produce more consistent secondary metabolite expression across growing environments. Documentation of how a strain family responds to standard curing protocols helps breeding programs predict final potency and terpene retention.

Breeders selecting parent plants often evaluate post-harvest stability and terpene preservation as heritable traits, since some lineages naturally retain volatile compounds better during cure cycles. Seed stock from cultivars with predictable post-harvest metabolism profiles provides more reliable phenotypic consistency for downstream breeding work and commercial production.
