Correct Calcium Disorders: Calcium sprays and cultural practices can help control bitter pit and cork spot

摘要

CORK spot and bitter pit are physiological disorders related to calcium deficiency, and sometimes to high nitrogen, in fruit flesh. Low calcium has also been implicated in poor storage quality. York Imperial, Delicious, Golden Delicious, and, even more recently, Braeburn are varieties that are particularly susceptible, although others can be affected. These problems continue to cause producers economic losses.
