摘要
The aim of the conducted investigations was to determine the effect of storage in selected cultivars of plum Prunus domestica L. on changes in contents of polyphenolic compounds, fruit mass as well as dry mass and solids contents. Plums harvested at the stage of harvesting maturity were stored for the period of 2 and 4 weeks in an ordinary refrigerator. During storage the total content of polyphenolic compounds, depending on the cultivar, increased by 16-88 % in comparison with the initial content in fruits after harvest. Fruits of 'Wegierka Dabrowicka' cv. exhibited a relatively low content of polyphenolics in comparison with the other analyzed cultivars, ie 'Wegierka Zwykla', 'Valor' and 'Cacanska Lepotica'. After storage an increase of dry mass and solids contents in fruits was observed, while fruit mass decreased.
