The objective of this research was to determine if copper concentration in the top plant tissue can be a reliable indicator of Cu toxicity. A four-year microplots experiment was carried out with 4 copper treatments: 0, 30, 60, and 90 kg ha 1. Spring wheat, red clover, and maize were grown on the microplots filled with sandy acid soil. In the first and second year, after application of the highest...
The effect of cadmium on growth parameters of seedlings of maize, rye and wheat as well as the role of phytochelatins in Cd detoxication in these species were studied. Cadmium was found to inhibit root growth and decrease fresh weight and water content in roots and shoots of the studied plants. Although a considerably lower Cd accumulation was shown in maize seedlings than in other species, they were...
