, localized Ca deficiency such as in leaves or fruit may still become a problem in fruit crops. Calcium-related disorders include bitter pit in apple fruit ( Malus domestica , Borkh.), blossom-end rot in tomato ( Solanum lycopersicum L.) fruit, and tipburn in
storage ( Smock, 1977 ). Common examples of these disorders include superficial scald, soft scald, bitter pit, soggy breakdown, water core, and various types of flesh browning. Prestorage treatment, such as diphenylamine (DPA) dips, 1-methylcyclopropene (1
