The growth response of Coelastrum proboscideum Bohlin to cadmiun (3 × 10 −9 M to 2.4 × 10 −7 M ) was studied. The inorganic media used varied in zinc concentration (1.3 × 10 −7 M to 3.6 × 10 −6 M ). The data were evaluated by factorial analyses. The influence of zine on the growth depression by cadmium depended on the light conditions (16:8 h light:dark cycles or 24 h continuous illumination periods). Intermittent illumination caused a negative interaction of zinc and cadmium in contrast to a positive interaction or additive effects of these elements during continuous illumination.
