To understand the interactions between nanoparticles and coffee plant physiology, the aims of this investigation were (i) to compare plant growth responses of coffee plants to zinc sulfate (ZnSO 4) and zinc nano-fertilizer (ZnO NPs) and (ii) to analyze the Zn uptake and the physiological changes in coffee leaves treated with ZnSO 4 and ZnO NPs. Researchers report a big gap in knowledge about the effects of nanoparticles on rice, tomatoes, corn, and other food crops [ 63 - 65 ]. Carbon-based nanoparticles, such as fullerenes, nanotubes, the oxides of metals such as iron and titanium . Powdery mildew is one of the most devastating diseases in cucurbits. Moreover, plants treated with silver nanoparticles showed higher leaf greenness index, formed more Meanwhile more investigations reported that nanopaticles had no effect on germination but did influence the growth of plants. . . The plants were sprayed 3 times at the interval of 15 days with graded concentrations of zinc oxide nanoparticles (ZnO NPs) along with sticker. To our best knowledge, it was the first time to investigate the influence of Fe 2 O 3 Nanoparticles can be used for multiple plant protection purposes, such as pathogen detection (nanodiagnostics), pest control (against microbial pathogens, fungi, bacteria and insects), weed control, pesticide remediation, induced resistance and so on.

Seeds of rice were primed with different concentrations (10, 20, 50, 100, and 200 mg L-1) of ZnO NPs and As (0, and 2 mg L-1) for 12 days in petri dishes. Abstract: The uptake, bioaccumulation, biotransformation, and risks of nanomaterials (NMs) for food crops are still not well understood. As a result, Si could boost plant resistance to bacteria, fungus, nematodes and viruses [30]. Further, the nanoparticles alter the gene expression of different genes and miRNAs that have a positive impact on stress tolerance and plant biomass. A new study aimed to provide new information about phytotoxicology of nanoparticles (multi-walled carbon nanotube, aluminum, alumina, zinc, and zinc oxide) on seed germination and root growth of six higher plant species (radish, rape, ryegrass, lettuce, corn, and cucumber). negative effect on the growth of Phaseolus vulgaris and Lolium perenne in the tested concentration range. The release of metal ions may play an important role in toxicity of metal‐based nanoparticles. In plants, AgNPs are transported via the intercellular spaces (short-distance transport) and via vascular tissue (long-distance transport) [29,39,40,41].After exposure to plants, NPs penetrate cell walls and plasma membranes of epidermal layers in roots, followed by a series of events to enter plant vascular tissues (xylem), and move to the stele. An experiment was conducted to study the effect of seed invigoration with inorganic nanoparticles on plant growth and seed yield of chilli. This Paper . Presently, many kinds of metal oxide NPs have been applied in agriculture, specifically in fertilization and plant protection in abiotic and biotic stress conditions [ 8, 9 ]. An element is considered quasi-essential if it is not required by plants but its absence results in significant negative consequences or anomalies . increased gradually and signicantly with increasing concentration of Fe 3 O 4 NPs. [ 7 ]. Nanoagriculture utilizes nanotechnology to improve the yield of plants for food, fuel, and other uses. Data regarding plant height, number of tillers per plant, spike length were recorded and then samples were washed with distilled water and oven-dried at 70 °C and dry weight of shoots, Titanium dioxide nanoparticles (TiO 2 NPs) display an array of effects from negative, to neutral and positive when applied on plants.

Silicon (Si) is considered a non-essential element similar to cadmium, arsenic, lead, etc., for plants, yet Si is beneficial to plant growth, so it is also referred to as a quasi-essential element (similar to aluminum, cobalt, sodium and selenium). Very few NMs and plant species have been studied, mainly at the very early growth stages of the plants. neighboring to, the notice as competently as keenness of this influence of nanoparticles on seed germination and can be taken as well as picked to act. The objective of this study was to evaluate the toxicological effects of silver and zinc oxide nanoparticles on bacteria classified as plant growth-promoting bacteria. NPs influence on plant growth and development. Seed invigoration with nano particles of ZnO and TiO2 was found to be beneficial in improving yield and yield PDF - Nanofertilizers have become a pioneer approach in agriculture research nowadays. A direct promotion of plant growth is brought about when these bacteria use any of the following mechanisms—nitrogen fixation, phosphate solubilization, and synthesis of phytohormones, siderophores, and antibiotics [15-19]. Results indicated that with concentration increased, the available Cu content in . AgNPs stimulated plant growth, as manifested by enhanced accumulation of leaf and bulb biomass and accelerated flowering. . In this paper we investigate the delivery of chitosan nanoparticles loaded with nitrogen, phosphorus and potassium (NPK) for wheat plants by foliar uptake. In this study, we evaluated the effect of silver nanoparticles against powdery mildew under different cultivation conditions in vitro and in vivo.Silver nanoparticles (WA-CV-WA13B) at various concentrations were applied before and after disease outbreak in plants to . several studies have revealed that specific (low-dose) concentrations of nps, foliar spray/irrigation, and carbon nanotubes significantly enhanced plant growth (plant height, root length, number of leaves, fruit size and production, seed germination, fresh shoot and root biomass), physiology (chlorophyll a, b, carotenoid content, photosynthesis, … The optimum concentration of nanoparticles causes an alteration in different physiological processes to increase seed germination and photosynthesis of the plants. Among many types of nanoparticles, metal and metal oxide nanoparticles show the profound effect on the morphology and physiology of the plants. govorov and carmeli ( 2007) conducted an experiment in which nag and nau were bound to the chlorophyll of the reaction centre of psi forming a unique hybrid system, leading to two contradictory effects on photosynthetic efficiency, i.e. Nanoparticles have the ability to enhance growth and yield of different plants such as fenugreek ( Trigonella foenum-graecum) (Fabaceae). This could result in undesirable changes in the environment and affect workers in indoor and outdoor workplaces.
