Trichomes Glandular Capitate Sessile

Glandular capitate sessile trichomes are small, stationary resin-producing structures that sit directly on the cannabis leaf or flower surface without a stalk. Unlike their stalked counterparts (capitate-stalked), these trichomes lack the elongated stem, making them more compact and closer to the plant tissue. Breeders and researchers identify these structures through magnification as part of trichome morphology assessment. Their presence and density vary significantly across cultivars and are influenced by both genetic background and environmental conditions during growth. Capitate sessile trichomes contribute to the overall secondary metabolite profile that breeders seek when developing new genetics.

Breeders monitor capitate sessile trichome expression as a heritable trait when selecting parent plants, as trichome morphology correlates with resin production capacity and secondary metabolite concentration. Understanding the ratio of sessile to stalked trichomes helps inform breeding decisions for desired plant chemistry and structure.
