Résumé

Polyphenol oxidase (PPO) activity was found to be low in the leaves, roots, inflorescence tissues and developing and mature fruit of pineapple (Ananas comosus cv. Smooth Cayenne). In fruit affected by the chill-induced internal browning disorder known as black heart, PPO activity was 10-fold higher than in unaffected fruit, and there was a direct correlation between PPO activity and the severity of black heart symptoms.
