Abstract
The effects of toxic concentrations of Cu, Zn and Cd on the fast induction kinetics of fluorescence from photosystem(PS)II were investigated in a comp arative way. The fast fluorescence transient from primary leaves of metal-t reated bean plants was studied. During several days after metal application , the time course of the changes induced by the different metals was monito red. The results evidenced not only a different time course of the changes in fluorescence related parameters for the three metals, but also different effects on the fluorescence induction kinetics, which could possibly be li nked to different mechanisms of action of the metals.
