Abstract
The effect of silicon nanoparticles on seed germination and seedling growth of Zea mays L. grown under cadmium (Cd) stress was estimated. The seeds were treated with combinations of four CdCl2 concentrations (0, 25, 50 and 100 mg/L) and four Si NPs concentrations (0, 5, 10 and 20 mg/L) for 4 h before germinating in distilled water. Si NPs significantly enhanced seed germination traits (final germination percentage, mean daily germination, germination rate index, peak value and germination value) and seedling growth (seedling weight, and vigor indices) under cadmium stress but decreased mean germination time and seed mortality under cadmium stress. Therefore, the application of Si NPs could reduce Cd toxicity and enhance seed germination and seedling development in Zea mays L.
