Hierarchical clustering analysis (HCA) of peach fruits from six varieties subjected to different postharvest treatments depending on metabolic profile. Peach fruit samples from six varieties (FD, R2, SL, RG, EL, and LM) subjected to different postharvest treatments (H, RS, CS, CS21, and CS21+RS) are divided in two principal clusters depending on harvest time (early vs. mid & late varieties). Further divisions are dependent on the variety or the particular postharvest treatment. Cold-treated samples are indicated in blue and with an asterisk (^*), while ripened samples (RS) are indicated in red. Resistant to mealiness varieties (LM, SL, RG, and EL, Table 1) are marked with a rectangle.
