Abstract

silicon is an essential nutrient element for some herbaceous plants and a useful element for improving the growth and to encounter with biotic and abiotic stresses. This research was carried out on natural contaminated soil with heavy metals from Zanjan Industrial Town. The effect of nano-silicon particles application on morpho-physiological and nutritional responses of Lolium perenne was investigated. Nano-silicon treatments were selected in six levels of 100 (NS1), 200 (NS2), 500 (NS3), 1000 (NS4), 2000 (NS5), and control treatment (N0) (in mg/kg). Experiments were carried out in a completely randomized design in greenhouse conditions. Nano silicon added to soil by usage of pipette method. After the planting and cropping stages of Lolium perenne, the aboveground parts, the concentration of heavy elements (lead, zinc and cadmium) and nutrient elements (phosphorus, potassium and silicon) were measured. Results showed that application of silicon on the adsorption of cadmium and zinc and nutrient elements of potassium, phosphorus, and silicon was significant at 5% level. Also, the application of silicon in soil increased the absorption of zinc and cadmium contaminants in the plant. The highest amount of silicon adsorption in Lolium perenne was observed in NS5 treatment, which showed a significant difference compared to other levels of nano and control treatment. In general, application of silicon improved plant growth and increased the uptake of nutrients in the contamination/stress of the heavy metals.
