Correlation between the levels of nitrates and nitrites and the contents of potassium, calcium and magnesium in potato tubers
1998
Cieslik, E. | Sikora, E.
In tubers of 16 cultivars of consumable potatoes, cultivated in the Experimental Station of Varieties Appraisal at Wegrze near Cracow in years 1991-1992, the contents of potassium, calcium and magnesium as well as levels of nitrates and nitrites, were determined. Statistical analysis of results showed a significant effect of the year of cultivation and cultivar on the levels of nitrates and nitrites in tubers. A significant correlation between the levels of the studied compounds and the content of potassium in tubers was found; however, in the case of magnesium and calcium the correlation was statistically non-significant.
