| 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. |
