Related Observation Variables Summary 8

Name Description Trait
fruit shape circular Fitting precision R2. How well the boundary of a perfect circle fits the boundary of a fruit. The ratio of the error resulting from a best-fit circle to the area of the fruit. Error is the average magnitude of residuals (Res) along the fruit perimeter, divided by the radius of the circle. Smaller values indicate that the fruit is more Circular.Measured in transversal section ID:0000026
fruit shape ellipsoid Fitting precision R2. How well the boundary of a perfect ellipse fits the boundary of a fruit. The ratio of the error resulting from a best-fit ellipse to the area of the fruit. Error is the average magnitude of residuals (Res) along the fruit perimeter, divided by the length of the major (longer) axis of the ellipse. Smaller values indicate that the fruit is more ellipsoid.Measured in transversal section ID:0000028
fruit perimeter, measurement in centimeters The maximum perimeter of the fruit in cm. ID:0000005
fruit lobedness degree Fruit bumpiness index. The standard deviation of distances (d) from the center of the fruit (assuming all pixels have equal mass) to the perimeter, multiplied by 100. ID:0000078
pericarp area in square centimeter, cm^2 The area of the pericarp (cm^2).Measured in transversal section ID:0000025
pericarp thickness, calculation in centimetes Pericarp thickness in cm.Measured in transversal section ID:0000024
fruit shape rectangular The ratio of the area of the rectangle bounding the fruit to the area of the rectangle bounded by the fruit.Measured in transversal section ID:0000030
septum and pericarp area, calculation in square centimeters, cm^2 The sum of the areas of the septum and the pericarp in cm^2. ID:0000076
