Abstract
Oil pumpkin (Cucurbita pepo L. var. styriaca) seeds and Jerusalem artichoke (Helianthus tuberosus L.) tubers are alternative horticultural products containing important
biologically active components. The objective of the three-year study was to determine dry matter and micro-, macroelements accumulation in seeds of oil pumpkin Cucurbita
pepo L. var. styriaca – ‘Miranda’, ‘Golosemiannaja’, ‘Herakles’, ‘Danaja’, ‘Olga’; and in tubers of Jerusalem artichoke (Helianthus tuberosus L.) – ‘Rubik’, ‘Albik’, ‘Sauliai’ and selection lines Nr. 05-1, Nr. 05-7. Macro- and microelements were determined by mass spectrometer. The highest amount of Ca, K, Fe, Mn, Se and Al was accumulated in oil pumpkin seeds of cv. ‘Miranda’ and amount of Ca, Mg and Se was identified in cv. ‘Rubik’ and K, Na, in ‘Albik’ Jerusalem artichoke tubers.
