EFT and curvature analysis in a papillose-type seed. Dorsal view of a seed of S. perlmanii with the EFT curve superimposed in green and the corresponding curvature values plotted. The maximum and minimum curvature values correspond to individual tubercles. The EFT curve shown results from 184 points taken along the silhouette and 60 harmonics, following the protocol published [20]. The numbers indicate the correspondence between individual tubercles and their curvature values. Bar represents 1 mm. The program that provides the EFT curve contains the algorithm to obtain and represent the curvature values along it (see Supplementary Materials). Bar represents 1 mm.
