Abstract
The study carried out in Jordan University, College of Agriculture to investigate the relationship between apple fruit disorders and mineral content of N, Ca and Mg of apple fruits cvs. Fuji and Granny Smith after dipping in 0, 2 and 4% CaCl2 or 0, 500 and 1000 mg.1-1 AVG and storage at 0o c for three months. The results indicated that CaCl2 treatments were significantly increased fruit contents of Ca and significantly decreased fruit incidence with bitter pit in the Granny Smith cultivar, while no clear relationship noticed between AVG treatments and mineral fruit contents and disorder incidence. The increment of Ca content in the fruits, or the reduction of Mg/Ca and N/Ca ratios resulted in a reduction in bitter pit incidences. Granny Smith fruits was more susceptible to bitter pit disorder than Fuji fruits.
