The scar surface ratio (SSR) and the surface area of the apex (S_a) were measured on 10 individual fruits; the area of the individual vascular bundle (S_vb), the number of the vascular bundles in a scar (n_vb), the vascular ratio of the scar (VBR) on 5 individual scars; and the thickness of the cuticle (δ_c), palisade layer (δ_pl), and vascularised inner pericarp layer (δ_vi) on 5 slices of the main pericarp. Data are means ±1SE. Values with the same letters within each column were not significantly different at p>0.05 (One-Way ANOVA with Fisher’s LSD post hoc analysis).

The ratio presented as a percentage.
