“…The widespread inclusion of nanotechnology, especially nanoparticles (NPs), in the production of various products leads to their distribution in the environment (water, soil, air) and interaction with living organisms (bacteria, animals, plants) [ 1 , 2 ]. Due to their small size (1–100 nm) and high surface-to-volume ratio, NPs have unique chemical and physical characteristics compared to microparticles of the same metals [ 3 , 4 ]. They can pass through plant cell membranes, transport substances into cells, and integrate into metabolic pathways [ 5 , 6 ].…”

This work aimed to study the toxic implications of zinc oxide nanoparticles (ZnO NPs) on the physio-biochemical responses of spring barley (Hordeum sativum L.). The experiments were designed in a hydroponic system, and H. sativum was treated with two concentrations of ZnO NPs, namely 300 and 2000 mg/L. The findings demonstrated that ZnO NPs prevent the growth of H. sativum through the modulation of the degree of oxidative stress and the metabolism of antioxidant enzymes. The results showed increased malondialdehyde (MDA) by 1.17- and 1.69-fold, proline by 1.03- and 1.09-fold, and catalase (CAT) by 1.4- and 1.6-fold in shoots for ZnO NPs at 300 and 2000 mg/L, respectively. The activity of superoxide dismutase (SOD) increased by 2 and 3.3 times, ascorbate peroxidase (APOX) by 1.2 and 1.3 times, glutathione-s-transferase (GST) by 1.2 and 2.5 times, and glutathione reductase (GR) by 1.8 and 1.3 times in roots at 300 and 2000 mg/L, respectively. However, the level of δ-aminolevulinic acid (ALA) decreased by 1.4 and 1.3 times in roots and by 1.1 times in both treatments (nano-300 and nano-2000), respectively, indicating changes in the chlorophyll metabolic pathway. The outcomes can be utilized to create a plan of action for plants to withstand the stress brought on by the presence of NPs.

In recent years, nanotechnology has shown promising potential to enhance sustainable agriculture. Besides their use as antifungal and antimicrobial agents, silver nanoparticles (AgNPs) are the most widespread nanomaterials and are found in a capacious range of agrocommercial products. This study was designed to investigate the responses of morphophysiological characteristics in barley (Hordeum vulgare L.) to biologically synthesized silver nanoparticles. Spherical shapes with 8–20 nm size AgNPs at different concentrations (0, 50, 100, 150, 200, and 250 mg/L) were applied to barley plants in a hydroponic system. Following 7 days of sowing, the growth performance, chlorophyll contents, oxidative damage, and the activity level of antioxidant enzymes were quantified in different parts of the plant. The results indicated a remarkable boost in the growth performance and chlorophyll contents of barley plants up to a concentration of 150 mg/L. Interestingly, the levels of proline, lipid peroxidation, enzymes; superoxide dismutase (SOD), catalase (CAT), (APX), and (GR) activities were enhanced significantly in response to all AgNPs treatments. In general, the application of AgNPs substantially improved the growth and related morphophysiological attributes in barley. Our results provide new insights with respect to the effects of AgNPs on barley growth and their potential applications in increasing the performance of other crop species.
