Capitate Stalked Trichomes

Capitate-stalked trichomes are glandular hair structures featuring a stalk (stipe) topped with a large, multi-celled head (capitulum) that accumulates cannabinoids and terpenes. These structures are among the largest and most productive trichome types found on cannabis flowers, leaves, and stems. They develop primarily during mid-to-late flowering and are commonly associated with higher resin production across many cannabis lineages. The bulbous head contains numerous secretory cells capable of synthesizing and storing secondary metabolites. Capitate-stalked trichomes differ structurally from the more abundant capitate-sessile (no stalk) and filamentous (hair-like) types, making them a key morphological marker in breeding selection.

Cannabis breeders often select parent plants exhibiting abundant capitate-stalked trichome development as an indicator of resin yield potential and metabolite accumulation. Understanding trichome morphology helps breeders establish phenotype consistency and predict cannabinoid/terpene expression across generations.
