Trichomes Stalked

Stalked trichomes are glandular structures elevated on a cellular stalk or stem above the leaf and flower surface, distinguishing them from sessile (non-stalked) trichomes that sit flush against the plant tissue. This morphology is common in Cannabis sativa and hybrid cultivars, where the elevated position may increase surface area exposure and visibility of resinous heads. The stalk structure itself typically contains non-glandular cells, while the head—composed of secretory cells—produces cannabinoids, terpenes, and other metabolites. Breeders and researchers document stalk height, head diameter, and density as morphological traits that correlate with resin production potential and plant phenotype classification.

Breeders selecting for resin yield and trichome visibility often prioritize stalked trichome architecture, as elevated structures are easier to observe and measure during phenotyping. Stalk prominence is frequently recorded as a heritable trait in breeding records and cultivar documentation.
