Effect of Zno Nanoparticles on Chlorophyll Content of Wheat Plants (Triticum Aestivum L.)

Nanoparticles have achieved novel applications in biotechnology and agricultural industries. Nanoparticles on plants may cover a new insight to the ecosystems. There is a need for advance study of the possible effects of the nanoparticles on plant growth and development. In the present investigation, zinc oxide nanoparticles have been prepared by the simple chemical route and were authorized by UV-vis spectrophotometer and X-ray diffraction (XRD) analysis alongwith transmission electron microscope (TEM). The consequence of various concentrations of synthesized zinc oxide nanoparticles on wheat seeds (variety: lok-1) was studied by soaking approach and follow its effect on seedling growth of wheat (at 5 days). The seed germination, plant growth & chlorophyll content characteristics were measured by using standard biophysical techniques and studied. Results showed enhancement in germination and growth characteristics in five days grown wheat seedlings for control upto thousand ppm. Above thousand ppm, the considerable drop off was observed in these parameters upto two thousand ppm. Also, the chlorophyll content in the control sample is greater than the samples treated with the various concentrations of zinc oxide nanoparticles. There was a noticeable effect that employing suitable concentration of ZnO nanoparticles could support the seed germination of wheat in contrast to untreated control.

The Impact

In this study, we report synthesis of Zinc oxide nanoparticles using simple chemical and green methods. The ZnO nanoparticles were synthesized using leaf extract of Azadirachta indica (neem) as reducing agent. The as obtained product was characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy dispersive X-ray analysis (EDAX) and TEM techniques. XRD analysis confirms that ZnO nanoparticles were crystalline having hexagonal Wurtzite structure with (1 0 0), (0 0 2), (1 0 1), (1 0 2), (1 1 0) and (1 1 2) planes. SEM analyses show that the as synthesized ZnO NPs were in the form of agglomerates and no other impurity peak was found in the EDS. TEM analyses confirm that the size of the nanoparticle was approx. 50 nm. Here in, we investigate the effect of chemical and green synthesized zinc oxide nanoparticles on germination and growth of lycopersicum esculentus (tomato) using petri plate seed germination method in loamy sand soil. The impact of concentration of applied ZnO nanoparticles via green synthesis and chemical methods were analyzed. Results revealed that green synthesized Zinc oxide nanoparticles showed maximum growth of seedling as compared to chemically synthesized Zinc oxide nanoparticles, bulk ZnO and control. After 50 days of tomato growth analysis, it was recognized that ZnO NPs can be a good green synthetic fertilizer by increasing shoot length, wet weight, dry weight and yield over conventional control. Hence, green method is found to be more effective.

Abstract Zinc oxide nanoparticles (ZnO-NPs) are among the most commonly used nano-fertilizers (NF). However, elevated levels of ZnO-NPs in soil may affect plant growth and development due to its potential toxicity when accumulated in large amounts in plant tissues. This research was conducted using an in situ rhizobox system with the aims of evaluating Zinc uptake from nano-zinc oxide amended rhizosphere soil by alfalfa plant and the effect of plant growth promoting microorganisms on alleviating the phytotoxicity of ZnO-NPs. Treatments included microbial inoculations (Sinorhizobium meliloti, Serendipita indica) and different ZnO-NPs concentrations (0, 400 and 800 mg Kg− 1) with three replications. The results indicated that S. indica minimized the phytotoxicity of ZnO-NPs to alfalfa by enhancing growth rate and decreasing Zinc (Zn) translocation from root to shoot. Compared with plants inoculated with S. meliloti, co-inoculation with S. indica increased the shoot dry weight by 18.33% and 8.05% at 400 and 800 mg Kg− 1ZnO-NPs. However, at the highest level of ZnO-NPs (800 mg kg− 1), root inoculation of S. indica and S. indica + S. meliloti decreased Zn transfer factor by 60.2% and 44.3% compared to S. meliloti, respectively. Furthermore, a distinct relation between tolerance of S. indica-colonized plant to ZnO-NPs and the ability of S. indica in inhibiting or retarding degradation of polyunsaturated lipids through prevention of excess reactive oxygen species formation was observed. Malondialdehyde content of inoculated plants with S. indica either alone or in combination with S. meliloti was significantly lower than non-inoculated plants (p < 0.01). Zn-induced oxidative stress was mitigated by S. indica through enhanced activities of catalase and peroxidase enzymes. The findings of the present study indicate the potential use of endophytes fungus S. indica for ensuring food safety and security, and human health in heavy metal–polluted soil by reducing the phytoavailability of heavy metals in the aerial parts of the host plants.

Promising Alternative

With increase in incidence of multidrug resistant pathogens, there is a demand to adapt newer approaches in order to combat these diseases as traditional therapy is insufficient for their treatment. Use of nanotechnology provides a promising alternative as antimicrobial agents as against traditional antibiotics. Metal oxides have been exploited for a long times for their antimicrobial properties. Zinc oxide nanoparticles (ZnO NPs) are preferred over other metal oxide nanoparticles because of their bio-compatible nature and excellent antibacterial potentials. The basic mechanism of bactericidal nature of ZnO nanoparticles includes physical contact between ZnO nanoparticles and the bacterial cell wall, generation of reactive oxygen species (ROS) as well as free radicals and release of Zn2+ ions. This review focuses on different synthesis methods of ZnO nanoparticles, various analytical techniques frequently used for testing antibacterial properties, mechanism explaining antibacterial nature of ZnO nanoparticles as well as different factors affecting the antibacterial properties.

AbstractHighly stable semiconducting silver doped zinc oxide nanoparticles have been synthesized via facile, biomimetic and sustainable route, through utilization of Zinc acetate dihydrate (C4H6O4Zn · 2H2O) as host, Silver nitrate (AgNO3) as dopant and phytochemicals of angiospermic medicinal plant Prunus cerasifera as the reducing agents. Synthesis of Ag doped ZnO nanoparticles was done in a one pot synthetic mode by varying the amount of dopant from 0.2 – 2.0%. Synthesized photocatalyst nanoparticles were analyzed via UV-vis, FTIR, XRD and SEM. Commendable alleviation in the direct band gap i.e. 2.81 eV was achieved as a result of doping. Silver doped zinc oxide nanoparticles size ranged between 72.11 – 100 nm with rough surface morphology and higher polydispersity degree. The XRD patterns revealed the hexagonal wurtzite geometry of crystals with an average crystallite size of 2.99 nm. Persistent organic dyes Methyl Orange, Safranin O and Rhodamine B were sustainably photodegraded in direct solar irradiance with remarkable degradation percentages up to 81.76, 74.11 and 85.52% in limited time with pseudo first order reaction kinetics (R2 =0.99, 0.99 and 0.97). Furthermore, efficient inhibition against nine microbes of biomedical and agriculturally significance was achieved. Synthesized nanoparticles are potential green remediators of polluted water and perilous pathogens.
