Abstract:

At present, nanomaterials are widely used in agriculture and other fields. This paper aims to study the effects of nanomaterials on seed germination and growth and development of crop, and analyze the promoting and inhibiting effects of nanomaterials on seed germination and seedling growth and other growth. The effects of nanomaterials on crop growth and development were summarized, including breaking seed dormancy, promoting seed metabolism, affecting nutrient absorption, affecting net photosynthetic rate and water utilization rate, affecting plant stress resistance and inducing plant toxicity. It is pointed out that the interaction between nanomaterials and plants is a complex process. Moreover, the mechanism of interaction between nanomaterials and plants depends on the physicochemical properties and treatment concentration of nanomaterials, type and growth stage of plant, and environmental factors such as medium and light intensity. It is suggested that further study should be focus on the mechanism of interaction between nanomaterials and plants, establishing a scientific evaluation system fully reflecting the effect of nanomaterials on plant, and strengthening the application research of nanomaterials in agricultural resources and environment, in order to make nanomaterials play a good role in sustainable agriculture.

Key words: nanomaterials, crops, seed germination, growth and development
