European plums are susceptible to fruit cracking close to harvest. Heavy rainfall may lead to extensive damages leaving open wounds in the fruit flesh. In addition, cuticular fractures were found. Plum cultivar and stage of maturity are two major factors affecting the susceptibility to cracking. In order to reduce the plums’ susceptibility to cracking plum trees were treated with foliar fertilization during the growing season. Experiments included treatment with boron, calcium and nitrogen. Experiments including treatments with different levels of foliar fertilization did not show clear correlations between treatments and cracking in all cultivars. However, in some cultivars, more cuticular fractures were observed in fruits from nitrogen treated trees and less fractures in fruit from calcium or boron treated trees. In these experiments foliar fertilization with nitrogen, calcium or boron did not affect the amount of visible cracks in fruit significantly. Foliar fertilization is often shown to delay ripening. Even though fruit samples were picked at the same maturity stage, the effect of reduced cracking due to boron and calcium treatments could be partly an effect of differences in maturity. To make sure the fruits would develop fractures, unripe plum fruits on the trees were kept in a plastic bag with zip-lock and a few mL of water (to obtain 100% RH) for one week (from two to one week prior to estimated harvest date). In this way, the susceptibility of fruits on trees treated differently could be observed.
