Plant Surface Chemistry

Plant surface chemistry refers to the chemical composition and volatile profile present on cannabis plant surfaces, including trichomes, leaves, and flowers. This includes cannabinoids, terpenes, and other secondary metabolites that accumulate in glandular structures. Surface chemistry is influenced by genetics, environmental conditions, and harvest timing. Breeders and researchers study these compounds to understand strain expression and stability. Surface chemistry analysis helps document authentic genetic lineages and distinguish between similar cultivars.

Breeders monitor surface chemistry profiles as a phenotype marker to select for consistent terpene and cannabinoid expression across generations. Understanding surface chemistry helps create breeding targets and verify F1 stability in established crosses.
