Studies on the Internal Browning of Apple Fruits Caused by Excessive Boron Application


Abstract
Polyphenol greatly increased in apple fruits from trees receiving high level of borax. A strong positive correlation was detected between severity of internal browning and polyphenol contents. Polyphenol contents between fruit portions were highest in fruit flesh followed by fruit core and fruit skin in the order. Phenolic substances such as chlorogenic acid, catechol and flavonoid were detected on TLC. Those phenolics were decreased as browning was developed.
