Název v původním jazyce

Effect of cadmium stress on the uptake and distribution of microelements copper and zinc in plant parts of barley (Hordeum sativum L.)

Popis výsledku v původním jazyce

Effect of Cd-stress caused by Cd2+ (1.10-6 mol.L-1) in 32 days old barley plants cultivated hydroponically in special boxes under the same conditions as control plants were investigated for their microelement copper and zinc uptake from nutrient medium and distribution in roots, shoots and leaf blades. Cd-stress caused the increase of Cu by 27.9 % in the whole plant and Zn content was nearly the same (increase by 2.1 %) as compared with control. Cd-stress caused the increase of Cu content in roots (by 48.2 %) and leaf blades (44.8 %) and the decrease in shoots (by 32.9 %). Zn content increased under Cd-stress only in leaf blades (by 31.1 %), meanwhile in roots and shoots decreased (by 6.1 % and 4.5 %, respectively). Cd- stress enhanced copper and zinccontents in leaf blades, meanwhile in shoots their contents decreased in comparison with control. Differences were found in roots - an increase of Cu content from 15.6 mg.kg-1 DM to 23.4 mg.kg-1 DM and a decrease of Zn content from 109.6
