Fe2O3 and Fe3O4 nanoparticle applications were made at concentrations of 400, 800, 1200, 1600, and 2000 mg/L on Fagus orientalis seeds collected from 10 different populations, and some germination and seedling characteristics were evaluated. Preliminary results generally indicated that low-dose nanoparticle applications positively affected germination and seedling characteristics, while increases in doses led to decreases in these parameters. Values obtained from high-dose nanoparticle applications were generally lower than those from the control group. The iron nanoparticles affected the parameters to different extents, Fe2O3 nanoparticles showed a significant positive effect on germination rate and radicle length, while exhibiting a significant negative effect on germination percentage and plumule length. The populations least affected by high- dose iron nanoparticle applications were Bursa Inegol, Karabuk-Yenice, and Ordu Akkus, while the most affected were the Bartin-Kumluca and Kahramanmaras-Andirin populations.eninfo:eu-repo/semantics/openAccessNanoparticle2 O 33 O 4Fagus orientalisGerminationReview10.15376/biores.20.1.70-820013904698000117082201
