Investigation of the effect of zinc nanoparticles (Zn) on the growth parameters of wheat

Nanoparticles of zinc are one of the most widely used mineral particles that have been considered by researchers due to their suitable physical and chemical properties. These nanoparticles are used in cosmetics, agriculture, etc. In general, metal nanoparticles often cause toxicity when they accumulate in plant tissues. Therefore, this study was conducted to determine the effects of Nano-zinc accumulation on the growth parameters of wheat. After germination, the plants received nanoparticles in doses (۰.۲۵ mg / l and leaf spray) for ۱۵ days. The experiment was performed in the form of ۳ replications. Analysis of the results showed a slight increase in plant growth rate and pigments. As a result, the application of Nano-zinc did not have destructive biological effects on the wheat plant and to some extent increased plant productivity, which was more in Nano-zinc foliar spray.
