The effect of chromate on the synthesis of plastid pigments and lipoquinones in Zea mays L. seedlings

Zbigniew Krupa, Marek Ruszkowski, Ewa Gilowska-Jung

Abstract


Maize plants cultivated on nutrient solutions containing increasing amounts of CrO42- (from 10-7 to 10-4 M) showed growth inhibition, strong reduction of the root system and an increase of dry matter of leaves. The highest accumulation of chromium in plant organs appeared in the roots. Chromate taken up into leaves caused changes in the content of plastid pigments and lipoquinones similar, in general, to those in senescent plants.
