Terpene Accumulation Sites

Terpene accumulation sites refer to the specific plant tissues and structures where volatile compounds concentrate most heavily in cannabis. These primary sites include trichomes (particularly the glandular heads of capitate-stalked trichomes), leaf surfaces, and floral bracts. Understanding accumulation patterns is essential for breeders seeking to enhance aromatic expression and terpene yield. Different cultivars often show varying accumulation densities across these anatomical locations, making this trait valuable for phenotype selection and breeding program development.

Breeders working with terpene profiles examine accumulation site density as a heritable trait influencing harvest timing, extraction efficiency, and aromatic intensity. Selecting parent plants with robust trichome development and surface resin distribution has become standard practice in cultivar development programs.
