Silene seeds with white cardioid-like Model 4

<p>Graphic compositions containing forty seeds for each seed population of <em>Silene </em>species elaborated with Corel PHOTO-PAINT X7. For the comparison of a group of seeds with the models and the quantification of <em>J</em> index, the geometric figures used as models were superimposed to each seed image in the group of forty, searching a maximum adjustment between both shapes, the seeds and the model.</p> <p>The cardioid-like Model 4 in white is superimposed to 40 seeds in 3 species of <em>Silene</em>.</p>
