Capitate Stalked Glands

Capitate-stalked trichomes are glandular structures consisting of a stalk topped with a large, round head containing cannabinoids and terpenes. These visible, bulbous resin glands distinguish cannabis from many other plants and are commonly observed on mature flowers and sugar leaves. Breeders and cultivators track capitate-stalked density as a morphological trait linked to resin production potential. Their prominence varies by genetics, cultivation conditions, and harvest timing. Understanding trichome structure helps breeders select for desired resin profiles and assists in identification of plant maturity across different cultivars.

Breeders working in high-resin selection programs often prioritize capitate-stalked trichome density and size as visual markers of cannabinoid-rich phenotypes. Trichome morphology serves as a non-invasive screening tool in early-generation crosses, allowing rapid assessment of resin-producing potential without chemical analysis.
