Parameters considered for calculating the similarity index and its component measurements.

(a) Distribution in the horizontal plane (𝛽_symm)

(b) Diameter distribution (𝐷_symm)

(c) Deviation from the horizontal (𝜃_symm)

(d) Variability in the emergence of the laterals (LCM_symm)

(e) Tap root inclination angle with respect to the vertical (Tap_symm)

(f) Perfect similarity index
