摘要：The aim of the study was to present and compare characteristics of pomological
parameters, colour, dry matter and solids contents, as well as antioxidant
activity of fruit of selected plum cultivars. Analyses were conducted on plums
(Prunus domestica) of three cultivars: ‘Węgierka Zwykła’, ‘Bluefre’ and ‘Elena’.
Presented morphological parameters of fruit and stones included their length,
width and weight, as well as mean fruit size and firmness. Fruit colour was
measured by spectrophotometry in the L*a*b* system. Contents of dry matter and
solids were determined in fruits. Moreover, Trolox-equivalent antioxidant
capacity (TEAC) of plums was assayed by colorimetry using a cation radical ABTS.
The biggest fruits were found for cv. ‘Bluefre’, while the highest value of dry
matter and solids contents – in cv. ‘Węgierka Zwykła’. Higher antioxidant
activity (µM Trolox/g d.m.) was assayed in plums of relatively new cultivars,
‘Bluefre’ and ‘Elena’, in comparison to the traditional cultivar ‘Węgierka
Zwykła’.
