Trichome Types

Trichome types refer to the morphological structures on cannabis plant surfaces that produce and store cannabinoids, terpenes, and flavonoids. Cannabis cultivars display variation in trichome density, head diameter, and stalk length—traits often categorized as capitate-sessile, capitate-stalked, and bulbous forms. These structural differences are heritable and frequently documented in breeding records as markers for resin production potential. Breeders and cultivators observe trichome morphology as an indicator of chemical compound accumulation, though actual cannabinoid and terpene profiles require laboratory analysis to confirm. Understanding trichome architecture is foundational to cannabis genetics work, as these glandular structures directly relate to the plant's capacity for secondary metabolite synthesis.

Breeders select for trichome density and structure as indirect markers of resin-producing potential when developing cultivars. Trichome phenotype consistency across generations helps identify stable lineages and predict offspring resin characteristics in breeding programs.
