摘要: 采用不同质量浓度的纳米SiO2(0、150、300、450 mg/L)对髯毛箬竹进行叶面喷施处理,分析纳米 SiO2对髯毛箬竹叶片的生理影响。结果表明:各浓度的纳米SiO2处理可不同程度地提高髯毛箬竹叶片 的可溶性蛋白、游离氨基酸、全N、全P、全K含量,刺激SOD和POD保护酶活性,降低丙二醛的含量,并表现出一定的浓度和时间 效应,总体上以300 mg/L纳米SiO2处理效果最佳。说明300 mg/L的纳米SiO2处理能有效增强髯毛箬竹 叶片的营养功能及其对活性氧的清除能力,改善叶片生理功能。

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.
