摘　　要：碳点(CDs)是一种尺寸较小、水溶性和生物相容性较好、低毒或无毒的碳基纳米材料,在医学等领域已有广泛的应用,而在农业中的发展相对滞后。适宜的CDs可有效调控植物光合作用,促进植物生长,从而提高作物产量和品质。根据CDs清除自由基的特性,阐述了其缓解植物非生物胁迫的作用,如提高作物的抗旱性和耐盐性、缓解营养缺乏及重金属污染胁迫等,以及防治植物病害、作为基因沉默工具的作用。在农业生产中推广应用CDs时,还需考虑大规模合成以及降低成本等问题。Carbon dots(CDs)is a kind of carbon-based nanomaterials with small size,good water solubility and biocompatibility,low toxicity or no toxicity,which has been widely used in medicine and other fields,but the development in agriculture is relatively backward.Suitable CDs can effectively regulate plant photosynthesis and promote plant growth,thus improving crop yield and quality.According to the characteristics of CDs in scavenging free radicals,this paper expounded the effects of CDs in alleviating abiotic stress in plant,such as improving crop drought resistance and salt resistance,alleviating nutrient deficiency and heavy metal pollution stress,preventing and controlling plant diseases,and acting as a gene silencing tool.If CDs are to be widely promoted for use in agricultural production,considerations must also be given to issues such as large-scale synthesis and cost reduction.
