Effect of rootstock on levels of ammonium ions and yeast assimilable nitrogen in musts of the grapevine varieties 'Weißer Riesling' and 'Grüner Veltliner'

Original language description

This paper deals with the content of yeast assimilable nitrogen in grape musts originating from the winegrowing region South Moravia in the Czech Republic. Experimental data were collected in years 2007 and 2008 (rootstocks 'Kober 5BB' and 'SO4'; varieties 'Weißer Riesling' and 'Grüner Veltliner'). The obtained results showed that all musts contained high concentrations of both ammonium ions and yeast assimilable nitrogen (124.4 mg/l and 257.8 mg/l, respectively). A comparison of the two rootstocks indicated that average contents of ammonium ions were higher in the variant with the rootstock 'Kober 5BB', but these differences were not significant. Distinctive differences were found between both varieties under study: grape musts from the variety 'Grüner Veltliner' contained higher levels of ammonium ions and yeast assimilable nitrogen. It is well known that grapes of this variety contain high amounts of proteins.
