In this study, seeds of Triticum aestivum L. (Poaceae) were exposed to 0-100 microg/mL chromium oxide nanoparticles (Cr2O3, Nps) to study the phytotoxic effects on seed germination and seedling growth. It has been observed that 25-100 microg/mL Cr2O3, Nps inhibited the seed germination and seedling growth in concentration dependent manner. The present study suggests that release of Cr2O3, Nps in environment may adversely affect the wheat production.
在这项研究中，小麦（禾本科）的种子暴露于 0-100μg/mL 的氧化铬纳米颗粒（Cr2O3，Nps）中，以研究其对种子萌发和幼苗生长的植物毒性影响。结果表明，25-100μg/mL 的 Cr2O3，Nps 以浓度依赖的方式抑制种子萌发和幼苗生长。本研究表明，环境中 Cr2O3，Nps 的释放可能会对小麦生产产生不利影响。
