Cannabinoid Storage Structures

Cannabinoid storage structures refer to the specialized glandular tissues in cannabis plants where THC, CBD, and other cannabinoids accumulate. These include trichomes (the crystalline, hair-like structures covering flowers and leaves) and internal secretory cells within plant tissues. Understanding these structures is essential for breeders selecting for cannabinoid quantity and quality, as trichome density and morphology directly correlate with resin production. Different cannabis lineages exhibit varying trichome types—capitate-stalked, capitate-sessile, and non-glandular—each with distinct cannabinoid profiles. Preservation of these structures during harvest, drying, and storage significantly impacts the final cannabinoid composition available for analysis and breeding evaluation.

Breeders working with cannabinoid storage structures assess trichome development patterns, density, and maturation timing as indirect markers for cannabinoid accumulation potential. Selecting parent plants with robust, well-developed glandular tissues supports the development of cultivars with consistent resin production across generations.
