Total phenolic content of yacon [Smallanthus sonchifolius) rhizomes, leaves and roots affected by genotype

Original language description

The content of total polyphenols (TP) in rhizomes, leaves and tuberous roots of five genotypes from New Zealand, Germany, Ecuador and Bolivia cultivated on trial field plots of the University of Agriculture in Prague-Suchdol under field conditions from the 2003 harvest was determined spectrophotometrically by Folin-Ciocalteau phenol reagent. Obtained results were compared by means of dendrograms according to cluster analyses based on TP and morphological traits. In four genotypes the content of inulin and fructose was also determined. From the obtained results on the basis of similarity of obtained dendrograms a very close agreement between TP content in rhizomes and leaves and origin and morphological traits of yacon genotypes could be found. Five yacon genotypes could be classified into three groups. The NZLw genotype from New Zealand and genotypes from Ecuador (ECU) and Bolivia (BOL) were distinguished with high TP content in purple coloured rhizomes and leaves; whilst the New Zeala
