Dynamics of Ni accumulation and possible causes of Fe deficiency in amaranthus hybrids leaves

Cover Page

Abstract


Amaranthus paniculatus f. cruentus (Cherry jam) were grown in the phytotron on Johnson nutrient solution with 2 mM Fe3+-EDTA. Six weeks plants were treated with NiCl2. In the presence of 100 and 200 uM NiCl2 uptake of Fe in mature and especially young leaves sharply inhibited. Possible mechanisms of Ni and Fe competition and the role of this phenomenon in determining the level of phytoremediation potential of amaranthus plants are discussed.
