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

Abstract

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) in nutrition solution caused the decrease of F in the all parts of the plant. The relatively highest decrease was found in the roots (from 20.0 to 3.05 g/kg dry ma�er), lesser decrease in the shoots (from 24.2 to 9.33 g/kg dry ma�er) and the leaf blades (from 58.3 to 27.3 g/kg dry ma�er). Statistically significant decrease (at least P < 0.05) of F and increase of Cd contents in all the investigated parts of the plant was found. Statistically significant differences of F and Cd contents among barley roots, shoots, and leaf blades were found.

Oxidative stress and change in plant metabolism of maize (Zea mays L.) growing in contaminated soil with elemental sulfur and toxic effect of zinc

“…Zn × S P = 0.03 total polyphenol and flavonoid contents in barley roots (Dudjak et al 2004, Lachman et al 2005). The decrease in the level of maize SOD activity resulting from treatment with S can be ascribed to the protective effects of S, which alleviated oxidative stress caused by excess Zn.…”

The effect of anthocyanin-rich bilberry extract on the antioxidant system in roots of barley (Hordeum vulgare L.) cultivars under ionizing radiation

“…TP also has antioxidant properties. In barley, TP exhibit antioxidant properties because of their oxidation-reduction capacity and play an important role in the defense system against various stress factors (Lachman et al 2005). The flavonoids, including anthocyanins, are the most important compounds in phenolic groups.…”

Flavonoid biosynthesis genes in wheat

“…A considerable increase in the flavonoid concen tration can be a consequence of the negative environ mental influence on a plant organism (Chalker Scott, 1999;Farrant, 2000;Nozzolillo et al, 2002;Ryan et al, 2002;Lachman et al, 2005;Nagata et al, 2005;Plaza et al, 2009;Gordeeva et al, 2013;Khlestkina, 2013). Unfavorable environmental factors lead to the development of oxidative stress in plant cells, while flavonoids are capable of resisting or preventing it, thus defending a variety of cellular structures from destruction.…”
