Terpene Storage Structures

Terpene storage structures refer to the specialized glandular cells and resinous tissues where cannabis plants accumulate volatile and non-volatile terpenes. These structures—primarily trichomes and resin ducts—develop across leaves, bracts, and flowers, with density and morphology varying significantly among cultivars. Understanding terpene storage is central to cannabis breeding, as these structures directly influence the plant's aromatic profile, resin production, and overall secondary metabolite expression. Breeders select for plants with abundant, well-developed glandular systems to maximize terpene yield and diversity. Storage structure development is influenced by genetics, environmental conditions, and plant maturity stage, making it a key consideration in cultivation and breeding programs.

Breeders working in this category prioritize trichome density, morphology (capitate-stalked vs. capitate-sessile), and resin duct distribution as selectable traits. Plants with robust storage structures often correlate with higher volatile terpene retention and more complex aromatic profiles, making them valuable parents for lineage development.
