摘要:In the eight-days-long experiment, we investigated the influence of cadmium(II) ions (0, 5, 10, 50, 100 and 500 μM) on sunflower callus culture. We mainly focussed our attention on the growth. The obtained results were evaluated using the standard procedure, in which dependence of the fresh weight on the applied concentration was determined. We also used linear regression to evaluate the obtained results. Based on the slopes of the lines, we determined the degree of inhibition of growth in various experimental variants. The results obtained suggest that sunflower callus growth was most inhibited by concentrations of 500 μM of cadmium(II) ions and slightly stimulated by 10 μM of cadmium(II) ions compared with control.
