Bitter pit

Bitter pit

Bitter pit is a physiological disorder believed to be induced by calcium deficiency in apple fruits.

The incidence of bitter pit usually occurs during storage, but in some cases it can also develop at harvest. [cite web | url=http://www.rhs.org.uk/Advice/profiles0901/bitter_pit.asp | title=Gardening Advice: Bitter Pit | accessdate=2008-08-03 | publisher=Royal Horticultural Society ] This disorder has been studied for more than a hundred years and many approaches have been attempted to explain bitter pit development, but no one completely succeeded. The fact that total calcium in the fruit is not able to accurately predict bitter pit incidence has puzzled many scientists for a long time. The high correlation and no accuracy between calcium and bitter pit make the development of this disorder one of the most complex and challenging mechanism present in plants.
