The effect of site conditions, variety and fertilization on the content of polyphenols in potato tubers

Popis výsledku v původním jazyce

In precise field trials in the CR in the years 2004 and 2005 the effect of site conditions, yellow- and red-fleshed varieties and fertilization on the content of total polyphenols (TP) in potato tubers was investigated. From four localities in both yearssignificantly the highest TP content (by 5.7 to 13.4 % 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 fleshValfi variety a higher TP content by 52 to 153 % in average of both years in comparison to yellow flesh varieties was recorded. In the frame of the grouping of eight yellow flesh varieties Karin variety had the highest TP content and showed a significantincrease in comparison to Agria, Saturna and Asterix varieties by 67, 60 and 37 %. TP content was not demonstrably affected by fertilization with mineral fertilizers, but we recorded a tendency to less TP content (by 3 to 9.9 %) in the v
