“…These findings follow the trend of Hu et al [70] in Salvinia natans L. that reduced the POD activity and enhanced the CAT and SOD activity after the applicatuion of 25 nm ZnOx NPs. Similar results have been found in another study conducted in Gossypium hirsutum L. [71]. A study by Sharifi-Rad et al [72] described the application 100 ppm of the ZnOx NPs to Momordica charantia L. that significantly boosted the activity of CAT, endorsing the validity of our findings.…”

Climatic variations adversely affect the limited water resources of earth which leads to water stress and influences agricultural production worldwide. Therefore, a novel approach has been introduced to improve the tolerance against water stress in herbaceous nature medicinal plants such as Coriandrum sativum by the usage of nanotechnology (foliar applied nanoparticles of ZnOx) coupled with the application of water deficit irrigation. This is an alternative water saving strategy that proved to be efficient to mitigate the Coriandrum sativum tolerance against water stress regimes for sustainable yield production through the activation of antioxidant system. Thus, the phenomena of green synthesis have been deployed for the formation of Zinc oxide nanoparticles (ZnOx NPs) from the leaf extract of Camellia sinensis L. and zinc acetate dihydrate was used as precursor. Different techniques have been used for the thorough study and confirmation of ZnOx NPs such as UV-vis spectroscopy (UV-vis) X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and Elemental dispersive spectroscopy (EDS). The prepared ZnOx NPs exhibit hexagonal wurtzite crystal nature has an average size of 37 nm with high purity. These ZnOx NPs have been further studied for their role in amelioration of water stress tolerance in Coriandrum sativum in a pot experiment. Two levels of water stress regimes were employed, IR75 (moderate) and IR50 (Intense) to evaluate the behavior of plant compared to full irrigation (FI). Results showed that under water stress regimes, the 100 ppm of prepared NPs stimulate the antioxidant system by increasing the activity of catalases (CAT), super oxidases (SOD) and ascorbate peroxidase (APX) enzymes and found the maximum at IR50, while the concentration of malondialdehyde (MDA) decreased due to increase in activity of antioxidative enzymes. Furthermore, chlorophyll content and amount of proline also enhanced by the foliar application of prepared ZnOx NPs under moderate water stress (IR75). The results suggested that all the investigated agronomic attributes significantly increased, including plant biomass and economic yield (EY), compared to non-treated ZnOx NPs plants, except for the number of primary branches and LAI. Further, the 100 ppm of prepared ZnOx NPs have great potential to improve water stress tolerance in Coriandrum sativum by improving the antioxidant enzymes activity that enhance agronomic attributes for high crop productivity that require further research at transcriptomic and genomic level.

“…The application of ZnO NPs to plants significantly promoted the protein content compared to the control. These results agree with those reported by [74], the effect of ZnO NPs as a regulatory cofactor in protein synthesis in the plant [75]. The present results suggest that higher protein contents could protect cells from any oxidative stress caused by higher concentrations of NPs and higher total protein contents.…”

The objective of this experiment was to evaluate the effects of grafting, zinc oxide nanoparticles (ZnO NPs), and their interaction on the nutritional composition of bell pepper plants. The treatments evaluated included grafted and non-grafted pepper plants with four concentrations of ZnO NPs (0, 10, 20, 30 mg L−1) applied to the foliage. The following parameters were evaluated: content of N, P, K+, Ca2+, Mg2+, Mn2+, Zn2+, Fe2+, Cu2+, total antioxidants, ascorbic acid, total phenols, glutathione, total proteins, fruit firmness, and total soluble solids. Grafting increased the content of N 12.2%, P 15.9%, K+ 26.7%, Mg2+ 20.3%, Mn2+ 34.7%, Zn2+ 19.5%, Fe2+ 18.2%, Cu2+ 11.5%, antioxidant capacity 2.44%, ascorbic acid 4.63%, total phenols 1.33%, glutathione 7.18%, total proteins 1.08%, fruit firmness 8.8%. The application of 30 mg L−1 ZnO NPs increased the content of N 12.3%, P 25.9%, Mg2+ 36.8%, Mn2+ 42.2%, Zn2+ 27%, Fe2+ 45%, antioxidant activity 13.95%, ascorbic acid 26.77%, total phenols 10.93%, glutathione 11.46%, total proteins 11.01%, and fruit firmness 17.7% compared to the control. The results obtained demonstrate the influence of the use of grafts and ZnO NPs as tools that could improve the quality and nutrient content in fruits of bell pepper crops.

“…Carbohydrates are carbon and energy sources in plant in vitro culture mainly to enhance cell division and enlargement. Priyanka and Venkatachalam (2016) suggest that ZnO NPs might up regulate protein expression resulting in growth promotion. Proline and MDA accumulation are the most reliable markers of oxidative stress (Yang et al, 2012), MDA is the product of lipid peroxidation caused by reactive oxygen species and leads to peroxidation of polyunsaturated fatty acids (Shulaev and Oliver., 2006).…”

Microbial contaminants are the major challenges in plant's in vitro propagation during different stages of culture processes, ZnO-NPs exhibit attractive antibacterial properties due to increased specific surface area as the reduced particle size leading to enhanced particle surface reactivity. The aim of present study was to evaluate the effect of ZnO NPs on microbial contamination; vitrification and growth promoting of date palm cultured tissues. Several concentrations of ZnO NPs were selected to assess their activity. The percentage of shoot formation, the number of proliferated shoot and the percentage of contamination of cultures were investigated, as well as several biochemical characteristics. Twofold of increase multiplication rate of proliferated shoot was observed in ZnO NPs at 150 mg L −1 compared to control treatment. The multiplication rate was 46.6% at control and increased significantly to 86.67% and 93.34% in ZnO NPs before and after sterilisation, respectively. No microbial contamination and vitrification were observed at all ZnO NP treatments compared with control treatment. Biochemical analysis showed that ZnO NPs had no toxic effects at all examined concentrations on date palm cultured tissues. A positive effect was observed in carbohydrates, protein and amino acid accumulations at high ZnO concentration (150 mg l −1). The results provide basis for the application of ZnO NPs in media date palm tissue cultures at 150 mg l −1 .
