Trichome Density Expression
Trichome density expression refers to the concentration and distribution of resinous glands across cannabis plant surfaces—leaves, bracts, and stems. This trait is heritable and influenced by both genetics and environmental conditions including light intensity, humidity, and cultivation timing. Breeders assess density by examining trichome clustering patterns, which range from sparse to heavily frosted phenotypes within a strain family. Documentation of trichome density helps distinguish cultivars and informs decisions about harvest timing and extraction suitability. Density expression is often correlated with cannabinoid and terpene concentration, making it a practical breeding marker for consistency.

Breeders select for specific trichome density profiles to stabilize visual phenotypes and predict resin yield potential. Dense trichome expression on mature flowers is commonly prioritized in cultivars developed for concentrate production, while moderate density supports balanced fresh-flower aesthetics.
