Trichome Structure Type Iii

Type III trichomes are bulbous glandular structures with a large, globular head sitting atop a short stalk, distinct from the more common Type I and Type II morphologies. These trichomes are commonly associated with plants displaying higher cannabinoid and terpene concentrations relative to their physical size. Type III structures appear less frequently across cannabis genetics compared to other trichome types, making them of particular interest to breeders selecting for resin production efficiency. The genetics controlling trichome morphology remain an active area of cannabis breeding research, with Type III expression often appearing in specific cultivar lineages.

Breeders working with Type III expression often prioritize these plants for cloning programs and line stabilization, as the morphology can correlate with desirable resin profiles. Understanding trichome structure inheritance helps guide crosses aimed at maximizing resin yield per plant mass.
