Interactive effects of Zn, Pb and Cd in barley.
The effects of different concentrations of Zn, Pb and Cd singly as well as in the combination of zinc-lead, zinc-cadmium and lead-cadmium on the shoot root length and dry mass as well as chlorophyll contents of barley plants during early seedling growth were studied. The effects of different concentrations of Zn x Pb and Pb x Cd in combinations showed a synergistic relationship, while at higher concentrations the relationship was antagonistic. Lower as well as higher Zn x Cd concentrations showed antagonistic effects.
