Studium vlivu dusikateho hnojeni na kvalitu konzumnich brambor.

This Ph.D. thesis was focused on evaluation of influence of nitrogen fertilization an its increasing rates, in comparison with the other factors )Years, site, cultivar) on selected qualitative parameters of table potato cultivars and tuber yield efficiency. Basic qualitative parameters of table potatoes, as average tuber weight (tuber size fractionation), dry matter content, specific gravity, and characteristic of sensory analysis in boiled potatoes (consistency, structure mealiness, moistness, favour, colour and its modifications after cooking) were evaluated. Special attention was given on analyses of nitrogenous compounds in potato tubers (total N content, protein content, nitrate content). The impact of nitrogen and agroecological conditions on content of patatin like proteins was emphasized. In evaluation of models , modification impacts of nitrogen fertilization, year, and growing site on electrophoretic protein profiles of cultivars for their application in verification of cultivar authenticity were studied.Available from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
