Plant Structure Leaf Area Index
Leaf Area Index (LAI) is a dimensionless quantity describing the ratio of total leaf area to ground area occupied by a plant. In cannabis cultivation and breeding, LAI influences light interception, photosynthetic efficiency, and canopy microclimate. Higher LAI phenotypes typically develop denser foliage and may require different training or airflow management. LAI varies significantly across strain families and is shaped by both genetic architecture and environmental conditions. Breeders track LAI as part of morphological profiling, especially when optimizing for indoor cultivation systems or specific production targets.

Breeders working in controlled environments often select for moderate LAI to balance yield potential with disease resistance and cultivation ease. LAI data informs decisions about plant spacing, light intensity, and canopy management strategies across different grow systems.
