In the agreement, maize seed treatment with a 20 mg/kg DW dose of nCu significantly enhanced germination rate after 7 days in the pot experiment (Figure 1A-B), plant growth after 90 days in the experimental station (Figure 1C) and maize yield (Figure 1D). In addition, 20 mg/kg DW nCu treatment upregulated concentration of grain mineral nutrients including Cu (Figure 1E), zinc (Zn) (Figure 1F) and calcium (Ca) (Figure 1G), but not iron (Fe) and potassium (K) (data not shown) as compared to the control plants. In contrast, the growth and yield indicators remained unaltered when maize seeds were treated with nCu at concentration of 1000 mg/kg DW, indicating that the dose of nCu at 20 mg/kg DW could stimulate the growth and development of maize plants and improve crop yield."}
