The Effect of Cadmium and Lead Exposure on the Development and Physical Structure of Quinoa (Chenopodium Quinoa Willd.)

The presence of soil affected by Cd and Pb and their metals is increasing daily. Quinoa is a plant that can grow in harsh conditions due to being a halophyte plant. This study was planned to examine the effects of lead and cadmium metals, two of the most common metals today, on plant growth, physiology and some biochemical properties of quinoa. Within the scope of the study, heavy metal applications were made as 1 control (no application), 4 doses of Cd (50, 100, 150 and 200 mg/kg), and 4 doses of lead (500, 1000, 1500, 2000 mg/kg). In this study, which was carried out in Atatürk University, Plant Production and Application Center greenhouse conditions, it is observed that the metals applied negatively affected the parameters in the plant, and cadmium metal had a more toxic effect than lead metal. It is determined that the fresh weight of the plant lost 62% at the Cd 200 level and 45% at the Pb 2000 level compared to the control group.
