Table II. Plant and canopy area properties.
Plants were separated into leaf and stem material and measured using a leaf area meter (LI3000C; LI-COR). Measured LAI was calculated as the total area (leaf + stem) divided by the area of ground each plant covered (distance between rows × distance within rows). The reconstructed LAI was calculated as mesh area inside the designated ray-tracing boundaries (see “Imaging and Ray Tracing” in “Materials and Methods”). P values correspond to ANOVA. Values are means ± se; n = 3.
