Effect of the growing regions and variety on the glycoalkaloid and polyphenol content in potato tubers

Original language description

Potato varieties Agria and Karin were cultivated in 12 sites of the Czech Republic that can be classified into two characteristic regions: i) traditional higher land region (cooler and more humid) and ii) lower land region (warmer and drier) between theyears 1995 and 1997. The harvested tubers were analysed for the content of total polyphenols (TP) and in the variety Karin also for the content of glycoalkaloids (GA). Significantly higher content of TP (46.3 mg.100g-1) was found from three years' results in tubers from traditional potato-growing regions with higher altitude compared with lower regions (43.5 mg.100g-1). Highly significant differences were found among varieties in the content of total polyphenols (TP) (in the variety Karin 53.0 and in the variety Agria 36.9 mg.100g-1). The effect of variety on the content of total polyphenols was manifested more significantly than the region. The effect of the year on the content of TP was not proved. In three years' average of the resul
