Chlorophyll levels show little change until the final 10-15 days before full shell yellowing and then decline (Gortner, 1965; Py et al., 1987). Shell carotenoid pigments remain reasonably constant during this phase, declining only slightly before rising again as the fruit senesces. Flesh carotenoids increase during the final 10 days before the full-ripe stage (Gortner, 1965; Teisson and Pineau, 1982; Py et al., 1987). A similar decrease in shell chlorophyll and an increase in flesh carotenoids occur in harvested fruit (Dull et al., 1967; Chen and Paull, 1995).
