Stem Pubescence
Stem pubescence refers to the fine, hair-like trichomes covering cannabis plant stems and petioles. This characteristic varies significantly across cultivars, ranging from smooth, glabrous surfaces to densely fuzzy coverings. Pubescence density and texture are heritable traits influenced by both genetics and environmental conditions like humidity and light exposure. Breeders working in cannabis genetics document stem pubescence as one of several morphological markers useful for cultivar identification and lineage tracking. The trait appears frequently in breeding records and seed catalogs as a secondary descriptor alongside leaf morphology and plant architecture.

Breeders observe stem pubescence patterns as part of phenotypic characterization protocols. Dense pubescence may correlate with humidity tolerance and pest resistance traits in some breeding lines, though causation remains understudied in cannabis genetics literature.
