Capitate Stalked

Capitate stalked trichomes are glandular structures with a distinct head-and-stalk morphology, consisting of a enlarged globular head sitting atop an elongated cellular base. These trichomes are among the largest visible structures on cannabis plant surfaces and commonly appear on flowers, leaves, and stems. The enlarged heads contain the highest concentrations of cannabinoids and terpenes, making them a primary focus in breeding programs. Capitate stalked trichomes develop most prominently during flowering and are often associated with mature, resinous cultivars. Breeders and researchers frequently examine trichome density and head size as markers of resin production potential, though visual observation alone cannot determine cannabinoid content.

Breeders working toward high-resin phenotypes select for capitate stalked trichome prevalence and head diameter as observable traits correlating with cannabinoid accumulation. Dense capitate stalked trichome coverage on flowers has become a conventional selection criterion in modern breeding programs, though lineage and environmental conditions significantly influence final expression.
