Organic Acid Metabolism

Organic acid metabolism refers to how cannabis plants produce, accumulate, and convert organic acids—including citric acid, malic acid, and other carboxylic compounds—throughout their lifecycle. These metabolic pathways are influenced by genetics, environmental stress, nutrient availability, and developmental stage. Breeders studying organic acid metabolism investigate how cultivars differ in acid production profiles, as these compounds contribute to plant vigor, terpene precursor availability, and overall biochemical complexity. Understanding acid metabolism helps explain variability in flavor precursors and plant physiology across different lineages. This classification is often explored in conjunction with terpene biosynthesis research, since many terpenes derive from shared metabolic pathways.

Breeders working in this category may select for or against specific acid accumulation patterns to influence downstream terpene expression, vigor under nutrient stress, or compatibility with extraction methods. Acid metabolism data can inform decisions about parent selection when targeting specific aromatic or metabolic profiles in offspring.
