Notes:
Pigments in the shell and flesh tissues of developing pineapple fruit were analyzed at weekly intervals on four different lots of fruit ripening in the spring and in the summer of 1963. Chlorophyll in the shell showed little change until final ripening began. It then disappeared during the final two weeks of development. Anthocyanin and chalcone compounds in the shell fell off steadily throughout fruit development. The carotenoid pigments in the shell showed a small downward trend during development, followed by a small rise during senescence of the fruit, after the chlorophyll had disappeared. In the flesh, however, the carotenoids showed quite marked changes. These pigments fell until about seven weeks before ripeness, then rose markedly during the final two-week ripening period. The trends in plant pigments are consistent with suggestions from earlier studies on nitrogenous, carbohydrate, and acid constituents of the pineapple during development, indicating that there are several discrete physiological stages for the fruit.
