| Abstract:
The aim of this research work was to study the effect of variety and cultivation region on mineral elements and protein content of white asparagus spears (Asparagus officinalis L.). Therefore an extended field survey was conducted in the regions of Braunschweig (Lower Saxony) and Erfurt (Thuringia). Statistically significant differences between cultivation regions were found for Ca, Mg and sulphate. Additionally, spear samples of crop performance experiments with new varieties and genotypes in Lower Saxony and Schleswig-Holstein were analyzed. For nitrate and sulphate significant differences were found between varieties in Schleswig-Holstein. In Lower Saxony, genotypical differences were determined for nitrate, sulphate, Ca, S, Fe, Zn, Mn and Cu. | |
