| Abstract: | The effect of Cd, Cu, Zn, Hg, and Pb solutions at various concentrations, on the restoration potential of the leaves of Portulaca oleracea was tested. All the trace metals completely affected the shoot regeneration. The degree of their effect on root regeneration, however, varied. Early initiation of parental leaf decay was also observed. The order of their relative effect on the regeneration process was: Cd > Cu > Zn > Hg > Pb. |
