Název v původním jazyce

Effect of cadmium on flavonoid content in young barley (Hordeum sativum L.) plants

Popis výsledku v původním jazyce

The effect of an abiotic stress caused by cadmium on the total flavonoid content in roots, shoots and leaf blades of spring barley variety Kompakt grown in a climate-control room for 28 days was investigated. Total flavonoid content (F) was determined spectrophotometrically with sodium nitrite, Cd content by atomic absorption spectrometry. Treatment of barley plants with Cd (1.10-6 mol.L-1) in nutrition solution caused the decrease of F in the all parts of the plant. The relatively highest decrease wasfound in the roots (from 20.0 to 3.05 g.kg-1 DM), lesser decrease in the shoots (from 24.2 to 9.33 g.kg-1 DM) and the leaf blades (from 58.3 to 27.3 g.kg-1 DM). Statistically significant decrease (at least p < 0.05) of F and increase of Cd contents in the all investigated parts of the plant was found. Statistically significant differences of F and Cd contents among barley roots, shoots, and leaf blades were found.
