Gland Density

Gland density refers to the concentration and distribution of trichomes—the resin-producing structures—across a cannabis plant's flowers, leaves, and stems. Breeders assess gland density by examining trichome coverage patterns, which vary significantly among cultivars and can be influenced by genetics, growing conditions, and maturation stage. High gland density typically correlates with visible crystalline appearance, while lower density may present a smoother flower surface. This trait is documented in breeding records as a measurable phenotypic characteristic that affects visual presentation and resin yield potential. Gland density is often evaluated during strain development to maintain consistency across generations and is commonly referenced in cultivar documentation and seed bank descriptions.

Breeders working in cannabis genetics track gland density as a selectable trait when developing cultivars for specific market segments or production goals. Consistent gland density across a line helps maintain recognizable phenotypes and supports standardization in breeding programs.
