Abstract :This study was carried out to determine the tolerance level of cadmium and lead applications at different concentrations on physiological and morphological parameters in soybean (Glycine max L.) The experiment was carried out in Atatürk University Plant Production Application and Research Center greenhouses. Yeşilsoy variety of feed soybean (Glycine max L.) was used as plant material. Plant growth (seedling height, stem diameter, fresh and dry weight, etc.), physiological properties (tissue proportional water content, tissue electrical conductivity) and biochemical parameters (chlorophyll amount, superoxide distumase (SOD), catalase (CAT), heavy metal applications) peroxidase (POD) enzyme activities, etc.) were investigated. All treatments had negative effects on all parameters compared to the control group. Growth retardation was experienced at the highest concentrations applied, but plant deaths were not observed. Although it is known that cadmium metal is more toxic than lead metal, the wet weight values of the plants to which the highest dose of both metals were applied were included in the same statistical group.
