Effect of Zinc Oxide Nanoparticles on some physiological properties of Hordeum Vulgare L

Marwa Kadhem Abed and Faiq Hassan Ali


Objectives: The goal of this project is to produce ZnO nanoparticles using inexpensive, ecologically friendly resources. Plant extracts can replace conventional and expensive chemical processes in the manufacture of oxide nanoparticles. In order to examine the biologically produced ZnO nanoparticles (SEM), transmission electron microscope (TEM), and scanning electron microscopy were utilized. Fourier-Transform Infrared Spectroscopy (FTIR) was then used to investigate the functional groups that were present in the samples. This study investigated the effects of three different methods (foliar plant, seed soaking, and foliar + seed soaking) and four different ZnO nanoparticle concentrations (0,50,100,150) on enzyme activities in Hordeum vulgare L. (Samir and Buhoth244).ZnO nanoparticle treatment had the greatest impact on total chlorophyll, carotene, carbohydrate, and protein when applied to foliar plants and seeds of the barely plant. The results also revealed an increase in all important indicators compared to the control treatment. Even while zinc is essential for plant growth, this study found that the presence of zinc in nanoparticles had a noticeably better impact.
