[An attempt to investigate the effect of magnesium ions and vitamin C on activity of nitrate reductase of white headed cabbage].
The aim of this study was to investigate the effect of magnesium ions and vitamin C on changes in the activity of nitrate reductase of white headed cabbage. During storage of cabbage the activity of nitrate reductase was investigated by the Jaworski method, the level of magnesium by complexometronic method and the level of vitamin C by the Pijanowski method. In addition, the effect of a supplement of magnesium and vitamin C on some changes in the activity of the enzyme was tested. For this purpose, to the incubation mixture, containing the material under study, magnesium ions in the form of magnesium chloride or vitamin C were added in respective quantities. It was found that the nitrate reductase activity as well as the level of magnesium and vitamin C are decreasing towards the inside layers of headed cabbage. Statistical evaluation of the results indicates a high by significant correlation between factors under study. A supplement of magnesium ions or vitamin C to the investigated cabbage significantly increases the activity of the enzyme.
