  1. The amount of carotenoids was measured at four stages of fruit ripening: white; white-pink; pink and red-ripe stages. Values are expressed as μg g-1 fw. Each value represents the mean result from triplicate ± SD. Data were submitted to one-way analysis of variance (ANOVA), values marked with different capital letters indicate statistically significant difference between ripening stages for a given carotenoid (Holm-Sidak post-hoc test, P < 0.05).
  2. fw, fresh weight; SD, standard deviation; Car, carotenoid; acy, acyclic; cy, cyclic; nd, not detectable. Italic formatting identifies dimentionless ratios.
