“…Zinc oxide nanoparticles were synthesized by a co-precipitation method using urea reduction of zinc nitrate hexahydrate at alkaline pH [63,64]. Briefly, 50 mL of 1 M urea solution was added to 50 mL of 0.5 M zinc nitrate hexahydrate solution while stirring at 600 rpm at room temperature for 15 min.…”

Producing high-quality table grapes is becoming a challenge in the warmer area of the world due to the global increase in temperature, which negatively affects anthocyanin biosynthesis and other fruit quality attributes. Nanotechnology is a growing field that can be a very useful tool to improve crop productivity and sustainability. The red color is one of the major fruit quality parameters that determine table grape marketability. This study aimed to investigate the role of the zinc element in improving the marketable characteristics of Crimson seedless (Vitis vinifera L.) table grape berries i.e., color, firmness, total soluble solids and sugars; besides its role in activating PAL and SOD enzymatic systems. Additionally, this paper investigated the additive advantages of zinc when applied in nanometric form. Five concentrations of zinc oxide nanoparticles, ZnO NPs (0, 25, 50, 100 and 250 ppm), were compared to zinc oxide in mineral form at a concentration of 250 ppm to investigate their effects on the marketable characteristics of Crimson seedless grape cultivar. The treatments were applied as foliar spray on three-year-old Crimson seedless vines grafted on Richter 110 rootstock grown in one of the major table grape production area in Egypt. The experiment was arranged in completely randomized block design and each vine was sprayed with five letters of the solution. The use of the lowest concentration (25 ppm) of ZnO NPs achieved the highest significant enzyme activity (PAL and SOD). Moreover, the T.S.S, sugars and anthocyanin content in berries increased significantly in association of decreasing acidity. On the other hand, the use of a 50 ppm concentration led to an increase in fruit firmness. Collectively, our data showed that 25 ppm of zinc nanoparticles improved PAL and SOD enzymes activity, improved red coloration in table grape and was more effective than the 250 ppm zinc oxide mineral form.

Hammam city, Matrouh Governorate, Egypt. This research was conducted on wild milk thistle (Silybum marianum var. albiflorum) cultivated and subjected to two precursors (phenylalanine and pcoumaric acid at 40 mg/L) and Chitosan nanoparticles treatments (Chs NPs 50 mg/L, Chs NPs 50 mg/L conjugated with phenylalanine 40 mg/L, Chs NPs 50 mg/L conjugated with p-coumaric acid 40 mg/L, Chs NPs 200 mg/L, Chs NPs 200 mg/L conjugated with phenylalanine 40 mg/L, and Chs NPs 200 mg/L conjugated with pcoumaric 40 mg/L) compared with the control (without the previous treatments). The study aimed to determine the effect of treatments on growth, yield, some biochemical and molecular markers. The DLS, zeta potential and X-ray diffraction were assigned for several fabricated Chs NPs. The significant highest increments in dry weight/plant, seeds weight/plant and seeds yield/feddan were obtained by phenylalanine 40 mg/L followed by Chs NPs 200 mg/L. Best biochemical markers were towards the same treatment. In the molecular level, there are no noticeable polymorphic changes in the plant genomic material with polymorphism average 59.83% for all treatments. The highest increases of total silymarin content in the plant seeds were detected by Chs NPs 200 mg/L, followed by phenylalanine 40 mg/L treatments. Concerning quantity and quality estimates, application of plants with engineered Chs nanoparticles A Asmaa A. Mahdi et al.

“…The application of AgNPs shielded wheat plants from heat stress by enhancing morphological growth [ 84 ]. Similar to this, Zn nanoparticles were discovered to be helpful in improving wheat’s ability to withstand heat stress by increasing the production of antioxidant enzymes and decreasing lipid peroxidation [ 85 ]. The foliar application of nanoparticles on tomato leaves becomes activated when the temperature exceeds certain limits and protects plants from heat stress.…”

In recent years, the global agricultural system has been unfavorably impacted by adverse environmental changes. These changes in the climate, in turn, have altered the abiotic conditions of plants, affecting plant growth, physiology and production. Abiotic stress in plants is one of the main obstacles to global agricultural production and food security. Therefore, there is a need for the development of novel approaches to overcome these problems and achieve sustainability. Nanotechnology has emerged as one such novel approach to improve crop production, through the utilization of nanoscale products, such as nanofertilizer, nanofungicides, nanoherbicides and nanopesticides. Their ability to cross cellular barriers makes nanoparticles suitable for their application in agriculture. Since they are easily soluble, smaller, and effective for uptake by plants, nanoparticles are widely used as a modern agricultural tool. The implementation of nanoparticles has been found to be effective in improving the qualitative and quantitative aspects of crop production under various biotic and abiotic stress conditions. This review discusses various abiotic stresses to which plants are susceptible and highlights the importance of the application of nanoparticles in combating abiotic stress, in addition to the major physiological, biochemical and molecular-induced changes that can help plants tolerate stress conditions. It also addresses the potential environmental and health impacts as a result of the extensive use of nanoparticles.
