Trichome Expression
Trichome expression refers to the visible density, size, and distribution of resinous glands across cannabis flower and leaves. These crystalline structures contain cannabinoids, terpenes, and flavonoids, making trichome development a key phenotypic marker in breeding programs. Expression varies significantly by genetics, environmental conditions, and maturity stage—some cultivars consistently produce heavy frosting, while others show lighter or more selective trichome coverage. Breeders often evaluate trichome morphology (bulbous, capitate-sessile, capitate-stalked) as an indicator of resin production potential. Dense trichome expression is commonly associated with preserved volatile compounds and is frequently selected for in commercial breeding lines.

Cannabis breeders monitor trichome expression as a visual phenotypic trait linked to secondary metabolite concentration. Consistent, robust trichome development across generations helps breeders identify and stabilize genetic lines with reliable resin production capacity.
