Özet
In this study, the effects of different sizes (30, 50, and 100 nm) and doses (200 mg and 400 mg kg<sup>−1</sup> soil) of copper oxide (CuO) nanoparticles (NPs) and copper (II) chloride (CuCl<inf>2</inf>) on agricultural soil samples and the growth of cucumber (Cucumis sativus) were evaluated. The effects of CuO NPs and CuCl<inf>2</inf> on cucumbers were assessed using the plant's biomass analysis as well as its antioxidant and oxidant status. Measurements of soil respiration, soil enzyme activity and copper content in soil and parts of plants were also performed. The results revealed that 30 nm CuO NPs led the lowest weight of roots and shoots of cucumbers compared to 50 and 100 nm CuO NPs, while CuCl<inf>2</inf> resulted in even lower weights. Oxidative stresses were found to be variable depending on the size of the nanoparticles and the dose of treatment. In the enzyme activity tests, dehydrogenase activity was significantly increased by 30 nm CuO NPs at 200 mg kg<sup>−1</sup> soil, while dehydrogenase activity was most inhibited by 100 nm CuO NPs at 400 mg kg<sup>−1</sup> soil. Alkaline phosphatase activity increased initially for all treatments but decreased after cucumber harvesting. The study concluded that CuCl<inf>2</inf> significantly reduced soil respiration compared to CuO NPs, and CuCl<inf>2</inf> accumulated more in plant leaf and root parts than CuO NPs. The size-dependent effects of CuO NPs on dehydrogenase and alkaline phosphatase activities varied, highlighting the diverse behavior of CuO NPs in soil properties and plant growth. This research contributes valuable insights for the strategic use of copper oxide nanoparticles in agriculture.
