Název v původním jazyce

Determination of saccharide content in octoploid and hexadecaploid clones of yacon (Smallanthus sonchifolius)

Popis výsledku v původním jazyce

Yacon [Smallanthus sonchifolius (Poepp. et Endl.) H. Robinson] is an Andean crop cultivated for its tuberous roots which contain fructooligosaccharides (FOS), which represent 70-80% of root dry matter. The aim of the work was to determine the effect of the ploidy level on the saccharide content in tuberous roots of yacon. The content of soluble saccharides (saccharose, glucose, fructose and FOS) was determined by the HPLC method in seven octoploids (2n=58; NZL I, NZL II, BOL, ECU, DEU, PER 10, PER 15/20) and one hexadecaploid (2n=116; Poly I - obtained experimentally by induced in vitro polyploidization from the clone NZL I), immediately after the harvest. The ploidy level was determined by flow-cytometric analysis and karyological studies. Significantdifferences (p < 0.05) for the FOS, fructose and saccharose contents were detected. Higher contents were detected in the hexadecaploid clone (FOS 12.74 g/100 g d.m., fructose 4.60 g/100 g d.m. and saccharose 1.93 g/100 g d.m.) compared t
