Plant Volatile Compounds

Plant volatile compounds (PVCs) are gaseous or easily evaporated organic molecules produced by cannabis plants, primarily terpenes, which form the chemical basis of aroma profiles. These compounds are synthesized in trichomes and other plant tissues as secondary metabolites, with production influenced by genetics, environmental stress, light exposure, and cultivation timing. Volatile profiles vary significantly across cultivars and are often used by breeders and researchers to distinguish chemotypes and lineages. Common volatile compound families in cannabis include monoterpenes (limonene, myrcene, pinene) and sesquiterpenes (caryophyllene, humulene), each associated with distinct sensory characteristics. Understanding PVC composition requires analytical methods such as gas chromatography or headspace analysis, which provide objective data beyond subjective aroma description. PVC researc

Breeders monitor volatile compound profiles to maintain cultivar identity across generations and to select for stable terpene expression. Understanding PVC genetics enables targeted crosses aimed at specific aroma families while maintaining other desired plant traits.
