Volatile Organic Compound Ratios

Volatile Organic Compound (VOC) ratios describe the proportional distribution of terpenes and other aromatic molecules in cannabis flowers and extracts. These ratios form the chemical backbone of strain aroma profiles and are determined by genetics, environmental conditions, and harvest timing. Breeders and researchers track VOC ratios to understand how different cannabinoid pathways and terpene synthase enzyme activity combine during plant development. The relative abundance of limonene, myrcene, pinene, caryophyllene, and dozens of minor compounds creates distinct aromatic signatures commonly associated with particular strain lineages. VOC ratio analysis has become a standard tool in cannabis breeding programs for phenotype selection and consistency across seed generations. Understanding these ratios helps contextualize why genetically identical plants can express different aromas unde

Breeders monitor VOC ratios to stabilize desirable aromatic traits and to differentiate cultivars within competitive markets. Selective breeding for specific terpene-ratio phenotypes requires multi-generational testing and controlled environment documentation to ensure reproducibility.
