Effect of Zinc Nanoparticles on Seed Priming, Growth and Production of Cucumber

Journal of Agriculture and Veterinary Science

Cucumber (Cucumis sativus L.) is an important vegetable and its demand remains around the year. High quality and yield are desired quality for both grower and consumers. Therefore, influence of seed priming and foliar application of zinc nano particles was checked on yield and quality of cucumber. ZnO nano particles are non-toxic and recently listed as “Generally Recognized as Safe (GRAS)” safe material by food and drug administration and use as food additive. Due to interaction of nano particles with plant, many physiological and morphological changes take place depending on the characteristic of Nanoparticles. By the exploitation of new application of nanotechnology crop yield can be increased. In plants, nano particles as a zinc fertilizer with small size and large surface area are predicted to be an ideal material to use. Zinc is one of the vital nutrients required for plant growth Result indicate that zinc nano particles at 20 ppm concentration increased seed germination as wel...

Onion Peel Waste Mediated-Green Synthesis of Zinc Oxide Nanoparticles and Their Phytotoxicity on Mung Bean and Wheat Plant Growth

Materials, 2022

Nanoparticles and nanomaterials have gained a huge amount of attention in the last decade due to their unique and remarkable properties. Metallic nanoparticles like zinc oxide nanoparticles (ZnONPs) have been used very widely as plant nutrients and in wastewater treatment. Here, ZnONPs were synthesized by using onion peel and characterized by various sophisticated instruments like Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), and field emission scanning electron microscopes (FESEM). FTIR confirmed ZnONPs synthesis due to the formation of the band in the region of 400–800 cm−1, while FESEM confirmed the spherical shape of the particles whose size varies in the range of 20–80 nm. FTIR revealed several bands from 1000–1800 cm−1 which indicates the capping by the organic molecules on the ZnONPs, which came from onion peel. It also has carbonyl and hydroxyl groups, due to the organic molecules present in the Allium cepa peel waste. The average hydrodynam...

Green synthesis of nano zinc oxide and evaluation of its impact on germination and metabolic activity of Solanum lycopersicum

Journal of biotechnology, 2016

In the present study, zinc oxide nanoparticles (ZnO NPs) were rapidly synthesized at room temperature by treating zinc acetate dihydrate with the flower extract of Elaeagnus angustifolia (Russian olive). The formation of ZnO NPs was primarily confirmed by UV-visible absorption spectrum in the range of 250-700nm. XRD analysis and DLS particle size analyzer revealed the size of ZnO NPs. The FTIR spectrum revealed the presence of phytochemicals in the flower extract mediated ZnO NPs. Moreover, the morphology of the ZnO NPs was determined using SEM. Seeds of Solanum lycopersicum (tomato) were separately treated with different concentrations of synthesized ZnO NPs and zinc sulphate (ZnSO4) salt suspensions (common zinc supplement). The effect of these treatments on seed germination, seedling vigor, chlorophyll, protein and sugar contents as well as on the activities of lipid peroxidation and antioxidant enzyme were studied. Leaves of plants treated with 6.1mM concentration of ZnO NPs rec...

Green Synthesis and Characterization of Zinc Oxide Nanoparticles Using Larrea tridentata Extract and Their Impact on the In-Vitro Germination and Seedling Growth of Capsicum annuum

Sustainability, 2023

The application of green methods in the synthesis of nanoparticles using plants is a cost-effective and eco-friendly approach. Zinc oxide nanoparticles are of great importance due to their versatile properties. The conditions of synthesis strongly influence the characteristics and functionality of the nanoparticles. The present work studied the biological, green synthesis of zinc oxide nanoparticles (ZnONPs) in the presence of different concentrations of ethanolic extract of Larrea tridentata (10, 20, and 30 mg/mL). The time of the formation of nanoparticles was evaluated at different temperatures and pH values of the reaction medium. The formation of ZnONPs was confirmed by ultraviolet-visible (UV-Vis) and Fourier transform infrared spectroscopies (FT-IR), as well as scanning electron microscopy (SEM). X-ray diffraction analysis (XDR) determined the crystallographic structure of the nanoparticles. Obtained ZnONPs had a size range of 18 to 40 nm. The temperature, reaction time, and pH significantly influenced the nanoparticles’ morphology, size, and aggregation. The impact of chosen ZnONPs was tested on the germination of serrano chili seeds (Capsicum annuum). At 100 ppm, the nanoparticles improved germination percentage, vigor, and seedlings’ growth parameters.

The potential of green synthesized zinc oxide nanoparticles as nutrient source for plant growth

Journal of Cleaner Production, 2019

In this work, the green ZnO NPs were synthesized using plant leaf extract (Aloe barbadensis Mill). Their formation was validated using a number of optical spectroscopic and electron microscopic techniques. The particle size of green ZnO NPs averaged as 35 nm which was far smaller than that prepared by conventional chemical methods for comparison purpose (e.g., 48 nm). Although both types of ZnO NPs were spherical with high crystallinity, the former is likely to better reflect the strong reducing and capping capability of the leaf extract. The suitable concentrations of ZnO NPs for seedling emergence and germination of wheat (Triticum aestivum L.) were then explored at varying NP levels (0, 15, 62, 125, 250, and 500 mg/L). Accordingly, the ones treated with green ZnO NPs grew better than the control seeds. Moreover, the wheat seed samples treated with a moderate amount (e.g., 62 mg/L) of green ZnO NPs showed most significant enhancement (P < 0.005) in their root and shoot length relative to other concentration levels or to the chemically synthesized ones (e.g., by 50% and 105%, respectively). As such, the potential of green synthesized ZnO NPs has been recognized as a nano-based nutrient source for agricultural applications.

In vitro germination and biochemical profiling of Brassica napus in response to biosynthesised zinc nanoparticles

Iet Nanobiotechnology, 2018

With the progression of nanotechnology, the use of nanoparticles (NPs) in consumer products has increased dramatically and green synthesis is one of the cheapest and eco‐friendly methods to obtain non‐hazardous NPs. In the current research zinc (Zn) NPs synthesis was carried out by using the fresh and healthy leaves of Mentha arvensis L. followed by characterisation through ultraviolet (UV)–visible spectroscopy, X‐ray diffraction (XRD) and scanning electron microscopy (SEM). UV–visible spectroscopy confirmed the green synthesis of ZnNPs, while XRD confirmed the size of NPs, which was 30–70 nm. SEM shows that the shape of ZnNPs was irregular. The effects of green synthesised NPs on two different varieties of Brassica napus were evaluated. Exposure to ZnNPs (5, 15, and 25 mg/l−1) caused a significant increase in root and shoot length of B. napus. The application of NPs significantly improved plant germination and triggered the production of secondary metabolite and antioxidant enzymes. ZnNPs showed a significant increase in chlorophyll, superoxide dismutase, total flavonoid content (TFC) and antioxidant enzymes while total phenolic content was decreased when TFC increased. Thus, it has been concluded from the current study that ZnNPs may possibly trigger the production of antioxidant enzymes and various biochemical compounds.
