Abstract
In the present investigation, the iron oxide nanoparticles (TFeONPs) were produced by ferrous chloride and aqueous extract of Tridax procumbens. The properties of as-synthesized TFeONPs were assessed. Moreover, the toxicity effects of TFeONPs on oilseed crops (Sesamum indicum and Arachis hypogaea) were investigated. The toxicity effect of TFeONPs on the germination of seed and formation of root and shoot of oilseed crops was determined using different concentrations of TFeONPs. The results of characterization confirmed that the synthesized TFeONPs were spherical-shaped. The various concentrations of TFeONPs significantly enhanced seed germination and the length of root and shoot of S. indicum and A. hypogaea. The highest concentrations (0.4% and 0.5%) of TFeONPs inhibited seed-germination and shoot and root formation, while the lowest and optimal concentrations (0.1-0.5%) of TFeONPs induced positive effects on seed germination and the length of root and shoot. The lowest concentration of TFeONPs was able to promote plant growth without any toxicity to other plants and the environment.
