Excerpt

Little is known about the effects of surface modification on the interaction of nanoparticles (NPs) with plants. Tomato (Solanum lycopersicum L.) plants were cultivated in potting soil amended with bare and citric acid coated nanoceria (nCeO 2, nCeO 2+ CA), cerium acetate (CeAc), bulk cerium oxide (bCeO 2) and citric acid (CA) at 0–500 mg kg− 1. Fruits were collected year-round until the harvesting time (210 days). Results showed that nCeO 2+ CA at 62.5, 250 and 500 mg kg− 1 reduced dry weight by 54, 57, and 64% and total sugar by 84 …
