Phytochemical Composition

Phytochemical composition refers to the complete profile of organic compounds present in cannabis plant tissue, including cannabinoids, terpenes, flavonoids, and other secondary metabolites. This molecular fingerprint is determined by genetics, environmental conditions during cultivation, and post-harvest handling practices. Breeders and researchers analyze phytochemical profiles to understand strain lineage, predict stability across generations, and document natural variation within cultivars. Modern testing labs quantify these compounds through techniques like HPLC and GC-MS, creating reproducible data for breeding records. Understanding phytochemical composition is foundational to cannabis genetics work, enabling predictable trait expression and informed cross-breeding decisions.

Breeders track phytochemical composition across generations to stabilize desired profiles, identify genetic markers for selection, and verify parentage in breeding programs. Consistent phytochemical data helps establish cultivar standards and informs decisions about which traits to concentrate or outcross.
