It is essential to understand the interactions of engineered nanoparticles (ENPs) with additives used in agriculture and their impacts on crop plants. In this study, kidney bean (Phaseolus vulgaris) plants were grown in potting soil amended with either nano copper (nCu), bulk copper (bCu), or copper chloride (CuCl) at 0, 50, and 100mg/kg, combined with 0, 10, or 100μM of kinetin (KN). Plant growth, Cu, micro and macroelement concentrations, chlorophyll content, and enzymatic activity were examined in 55-day old plants.

- The study explores how surface modification impacts the interaction of different cerium oxide nanoparticles with tomato plants, focusing on their effects on plant growth and fruit quality.
- Results indicated that citric acid-coated nanoceria (nCeO+CA) significantly reduced dry weight and sugar content in tomatoes across various concentrations, while bulk cerium oxide (bCeO) showed different effects by increasing certain sugars at higher doses.
- Overall, both types of cerium treatments altered the nutritional quality of the tomato fruit, with the coated nanoparticles having a notable impact on fruit macromolecule content and nutritional elements.
