ABSTRACT

Landscape plants are an important part of landscape architecture. Landscape plants can not only be used for plant landscaping, but also beautify the environment, improve the environment and regulate the climate, and play an important role in the stability of the ecosystem and the improvement of human living environment. The extensive application of nano-materials in industry, agriculture and other fields has led to a large number of residues in the soil and water environment, affecting the growth and development of garden plants. It has been proved that high concentration of nanomaterials have certain toxic effects on plants, but the research is not sufficient and needs further research. In this study, Rapeseed, an oil crop with ornamental and economic value, was taken as the research object, and nano-zinc oxide was used as the experimental material to explore its mechanism. The main results are as follows: The germination of Rapeseed seeds was studied by using the filter paper culture dish germination method. It was found that the germination rate of Rapeseed seeds under the treatment of nano-zinc oxide was not significantly different from the control. Compared with CK, under 400 mg•L-1 nano-zinc oxide and the same concentration of zinc oxide, the biomass of Rapeseed significantly decreased, and the photosynthesis of Rapeseed absorbed light energy through chlorophyll, while under 400 mg•L-1 nano-zinc oxide stress, the chlorophyll content of Rapeseed decreased, and the photosynthetic capacity decreased. Compared with CK, 400 mg•L-1 nano-zinc oxide and 400 mg • L-1 zinc oxide significantly increased the hydrogen peroxide content by 73.16% and 67.07%, respectively. Compared with 400 mg•L-1 nano-zinc oxide, 400 mg•L-1 zinc oxide significantly decreased by 3.52%; Compared with CK, each treatment significantly increased the content of superoxide anion, and compared with 400 mg•L-1 nano-zinc oxide, 400 mg•L-1 zinc oxide significantly decreased 4.81%.
