Leaf area index (LAI) is a dimensionless quantity that characterizes plant canopies.It is defined as the one-sided green leaf area per unit ground surface area (LAI = leaf area / ground area, m 2 / m 2) in broadleaf canopies.In conifers, three definitions for LAI have been used: . Typically, software programs can provide fluorescence intensity values for a defined ROI. As for perimeter estimation, surface area estimation in usually biased, but is usually more precise than measuring the surface area of the polygonal mesh reconstructed from binary images (Lehmann et al., 2012 11). It is in the public domain, runs on a variety of operating systems and is updated Measure (or keyboard M) transfers the area measurement to a data window.
