Principal component analysis of the fruits, considering the three variables cultivar (A), treatment (B) and time of treatment (C). KMO (Kaiser–Mayer–Olkin) index = 0.67. The components extraction criteria were: eigenvalue λ > 1 and varimax (orthogonal) rotation. The total proportion of the overall variance explained (e.v.) was 74.7%. PC1: λ = 3.9, e.v. = 36.0%. PC2: λ = 2.6, e.v. = 23.7%. PC3: λ = 1.7, e.v. = 15.0%.
