Capitate Stalked Glands

Capitate stalked glands are specialized trichomes that produce and store cannabinoids and terpenes on cannabis flower and leaves. These glandular structures consist of a stalk (often unicellular) topped with a head containing secretory cells. The morphology and density of capitate stalked glands are commonly associated with cannabinoid concentration and aroma profile variation across strains. Breeders and researchers frequently examine trichome populations—including capitate stalked, capitate sessile, and bulbous types—as visual markers during phenotype selection and strain development.

Capitate stalked gland density is often assessed as a quality indicator during breeding programs, as strains with robust populations of these structures typically develop denser terpene and cannabinoid profiles. Microscopic trichome evaluation helps breeders identify and stabilize desirable chemotypes across generations.
