Trichomes Glandular Capitate Stalked

Glandular capitate-stalked trichomes are among the most abundant resin-producing structures on cannabis flower and leaves. These multicellular trichomes consist of a narrow stalk (typically 1–4 cells tall) topped by a enlarged head or cap containing cannabinoid and terpene-secreting gland cells. Breeding programs and genetic studies frequently document this trichome type as a primary contributor to secondary metabolite accumulation in target phenotypes. The stalk allows the head to hold a greater volume of resinous material than shorter sessile or capitate varieties. Lineage records commonly associate this morphology with higher observed resin yields in F1 and stabilized lines.

Breeders working toward resin-heavy phenotypes often select for plants expressing dense capitate-stalked trichome coverage, as this trait correlates with measurable trichrome density counts and visual resin production in progeny trials. Growers and researchers use trichome microscopy to assess this trait during clone selection and breeding validation.
