Enzyme Activity

Enzyme activity in cannabis refers to the presence and concentration of naturally occurring enzymes that catalyze biochemical reactions in plant tissue. These include hydrolytic enzymes, proteases, and oxidative enzymes that break down complex molecules during growth, flowering, and post-harvest maturation. Enzyme activity levels vary significantly across cultivars and are influenced by genetics, environmental conditions, and harvest timing. Breeders and cultivators track enzyme activity because it affects terpene profile development, cannabinoid conversion rates, and the chemical processes occurring during curing and storage. Understanding enzyme activity is particularly relevant for breeding programs focused on flavor complexity and cannabinoid stability.

Breeders selecting for specific enzyme profiles aim to influence terpene expression and cannabinoid ratios during development. Higher enzyme activity in certain lineages may accelerate degradation of precursor compounds, which can shift final chemical profiles and affect shelf stability.
