Leaf Morphology Broad Leaflet

Broad leaflet morphology refers to cannabis plants exhibiting wider, more spatulate leaf structures compared to narrow-leaflet phenotypes. This trait is commonly associated with indica-dominant and hybrid lineages, though it appears across diverse genetic backgrounds. Leaf width influences light capture efficiency, transpiration rates, and overall plant architecture. Breeders have historically selected for broad leaflets in certain lines to optimize canopy structure and cultivar stability. The trait is inherited polygenically and can shift across environmental conditions and growth stages.

Breeders working in indica and hybrid development frequently prioritize broad leaflet expression for canopy management and aesthetic consistency. This morphology often correlates with compact growth patterns, making it valuable for indoor cultivation strategies and cultivar standardization.
