Comparative effects of nanoscale zero-valent iron (nZVI) and Fe2O3 nanoparticles on root hydraulic conductivity of Solanum lycopersicum L.
Original language description
The application of nanomaterials is progressively moving away from the experimental into practical areas. Nanoparticles have the potential to aggregate, and their interaction with plant root surfaces has been hypothesized to be a key factor in their phytotoxic effects. In an attempt to better explain their effects on plant physiology, this work investigated why nano zerovalent Fe (nZVI) and nano-maghemite (nFe2O3) affect differently the nutritional status of plants, through distinct effects on the root functionality. A hydroponic experiment, together with an incubation experiment, helped to relate the reduction of the root water uptake with the potential blockage of root nutrient uptake by each nanomaterial. The treatment with 100 mg L1 nFe2O3 inhibited a 40% the root hydraulic conductivity (Lo) of tomato plants (Solanum lycopersicum L.), which could explain the reduction in the Mo and Zn concentrations in their shoots. On the other hand, compared to nFe2O3, nZVI seems to be less harmful si
