Abstract: Physiological effects under the condition of spraying different concentrations(0,150,300,450 mg/L )of nano-SiO2 onto the Indocalamus barbatus McClure leaves were studied. The results showed that all concentrations of nano-SiO2 treatments could increase the contents of soluble protein, free amino acids, total nitrogen, phosphorus, potassium, stimulate SOD and POD activities, and decrease MDA content. Certain correlation of concentration and time would affect the effects. 300 mg/L nano- SiO2 treatment got the best effect which indicated that 300 mg/L nano-SiO2 treatment could effectively increase the nutritional function and the ability of scavenging active oxygen in Indocalamus barbatus leaves and improve the physiological function of leaves.
