Site conditions and genotype influence polyphenol content in potatoes

Original language description

In the years 2005 and 2006 the effect of site conditions, yellow- and purple-fleshed varieties and mineral fertilization on the content of total polyphenols (TP) in potato tubers was investigated. From four localities in both years significantly the highest TP content (by 5.7 to 56.3 % higher than in other localities) on the locality Stachy was determined, which we ascribe to apparently lower temperatures in the vegetation period in this locality of high altitude. In purple flesh Valfi variety higher TPcontent by 74 to 141 % in average of both years in comparison to yellow flesh varieties was recorded. In the group of eight yellow flesh varieties the highest TP content in Ditta variety was found, where we found significantly higher TP content by 38, 29 and 24 % in comparison with Saturna, Agria and Asterix varieties. TP content was not demonstrably affected by fertilization with mineral fertilizers.
