Trichome Types Capitate Glandular

Capitate glandular trichomes are the largest visible glandular structure on cannabis surfaces, featuring a stalk (stipe) topped with a bulbous, resinous head (gland). These are commonly associated with mature flower material and are often the primary targets for hand-collection or mechanical separation in breeding and processing workflows. The head diameter typically ranges from 50–100 micrometers, making them microscopically distinct from smaller capitate sessile and filamentous trichomes. Lineage records frequently report capitate glandular density as a marker for resin production capacity in target breeding populations. Their development intensifies during late flowering stages, making trichome maturity assessment a standard practice in cultivar documentation.

Breeders select for capitate glandular trichome abundance when developing cultivars intended for concentrate production or high-resin phenotypes. Trichome density and maturation rate are tracked across generations to stabilize commercial traits and assess genetic stability within established lines.
