Xylem- and Phloem-Based Transport of CuO Nanoparticles in Maize (Zea mays L.)

This work reports on the toxicity of CuO nanoparticles (NPs) to maize (Zea mays L.) and their transport and redistribution in the plant. CuO NPs (100 mg L–1) had no effect on germination, but inhibited the growth of maize seedlings; in comparison the dissolved Cu2+ ions and CuO bulk particles had no...
