Leaf Morphology Narrow Leaflets
Narrow leaflet morphology refers to cannabis plants displaying thin, elongated leaf segments—typically associated with sativa-descended genetics. This trait is often correlated with equatorial origins and appears frequently in breeding lines selected from regions like Colombia, Thailand, and Central Africa. Narrow leaflets tend to develop longer petioles and more open canopy architecture, influencing light penetration and airflow patterns. Breeders document this trait as a heritable characteristic useful for phenotype selection and hybrid structure prediction. The trait's expression can be modified by environmental factors including photoperiod, humidity, and nutrient availability during vegetative growth.

Breeders working in sativa-dominant crosses often select for narrow leaflet phenotypes to predict plant structure, flowering time, and canopy density. This morphological marker serves as a visual reference during early veg screening and is frequently tracked across F1 and stabilized lines for consistency documentation.
