AVENA SATIVA CADMIUM CONTENT, DISTRIBUTION AND TOXICITY IN DEPENDENCE ON CONCENTRATION OF ZINC AND NICKEL IN NUTRIENT MEDIUM

Popis výsledku v původním jazyce

In a pot experiment with Avena sativa L. under controlled climabox conditions a research on the effect of increasing concentrations of Zn (50, 500 and 1000 mu M) and Ni (50, 250 and 500 mu M) to Cd uptake by roots and its translocation to shoots was carried out. Cd concentration in the nutrient medium was uniform - 50 mu M. Cd uptake will be evidently influenced mainly by the Zn/Cd ratio in the nutrient medium. Doses of Ni in the medium on the other hand resulted in a slightly higher content of Cd in the roots. Zn and Ni significantly influenced Cd translocation from roots to shoots. This can be related to different mobility of Ni and Zn in the plant. Ni mobility in the xylem is significantly higher than Zn mobility, Cd mobility is probably the lowestof these elements. While in the variant with the application of only 50 mu M of Cd the Cd roots/shoots ratio was 2.00, in the variant with application of the same dose of 50 mu M of Cd and Zn the ratio was 1.43, and vice versa in variants
