| Abstract:
‘Flhoran 41’ is a red pineapple hybrid developed by CIRAD. Shell anthocyanins appear to be synthesized relatively early during the green stage, before ripening. Green fruits develop a deep reddish colour after 3 to 4 weeks in cold storage at 13°C but it is not a de novo synthesis. Anthocyanins are synthesized in larger quantity in fruits grown at high altitude (350 m) than those grown at sea level. With multilocal experimentation we could determine that a minimum sum of temperatures of 300 hours under 25°C between forcing and harvest is required to get most of the fruits showing the nice deep red color. HPLC analysis showed that most of these anthocyanins are cyanidin derivatives. | |
