Abstract

With the widespread applications of manufactured nanoparticles (NPs), there are increasing concerns about their potential adverse effects on the environment and living systems. Many studies demonstrated that NPs could significantly affect the growth and development of crop plants. However, knowledge regarding the impacts of NPs on crop quality is rather limited. In this study, the effects of CeO NPs (25, 75, and 225 mg Ce/kg) and CeCl (25 mg Ce/kg) on the nutritional components of soil-cultivated corn and soybean plants were evaluated. Both treatments tended to decrease the dry weight of grain per plant, while only 225 mg/kg CeO NPs on soybean and CeCl on corn showed statistical significance compared with the respective control. CeO NPs at 225 mg/kg significantly decreased the content of starch in the corn kernels by 18.2% but increased total phenols in soybean seeds by 18.4%. Neither CeO NPs nor CeCl significantly affected the contents of minerals in corn kernels except for Zn. However, in the case of soybean, the two treatments tended to decrease the contents of P, Zn, Mn, and Mo but increase the content of S. Overall, the results suggest that CeO NPs and Ce ions showed similar but not identical effects on corn and soybean plants. CeO NPs affect the nutritional quality of crop plants in a species-dependent manner.

摘要

随着纳米颗粒（NPs）的广泛应用，人们越来越担心它们对环境和生物系统的潜在不良影响。许多研究表明，纳米颗粒可能会对农作物的生长和发育产生重大影响。然而，关于纳米颗粒对作物质量影响的知识还相当有限。在本研究中，评估了 CeO NPs（25、75 和 225 mg Ce/kg）和 CeCl（25 mg Ce/kg）对土壤栽培玉米和大豆植株营养成分的影响。两种处理都倾向于降低每株植物的籽粒干重，而只有 225 mg/kg CeO NPs 处理的大豆和 CeCl 处理的玉米与相应的对照相比具有统计学意义。225 mg/kg 的 CeO NPs 显著降低了玉米籽粒中淀粉的含量 18.2%，但增加了大豆种子中总酚的含量 18.4%。CeO NPs 和 CeCl 都没有显著影响玉米籽粒中矿物质的含量，除了 Zn。然而，对于大豆，这两种处理都倾向于降低 P、Zn、Mn 和 Mo 的含量，但增加 S 的含量。总体而言，结果表明 CeO NPs 和 Ce 离子对玉米和大豆植物表现出相似但不完全相同的影响。CeO NPs 以依赖于物种的方式影响作物植物的营养品质。
