Abstract
The relationships between vitamin C and nitrates levels in mature tubers of 21 potato cultivars grown at the Experimental Station in Jadwisin in the years 1993–1999 were investigated. Statistical analysis of the results showed significant correlation between contents of the studied components. A negative value of correlation coefficient occurred when vitamin C / nitrates ratio was higher than 2. For the most part tuber samples were characterized by the ratios high enough to prevent the formation of harmful nitrosoamines. However, correlation between vitamin C and nitrates levels can sometimes be positive. This happens due to the excessive accumulation of nitrates in tubers of early and very early cultivars grown under dry and hot weather conditions. The decrease of vitamin C / nitrates ratio to about 1 is then observed.
