摘要

A laboratory-based Petri dishes experiment was conducted to investigate the role of silicon (Si) seed priming in enhancing drought tolerance in maize (Zea mays L.). Seeds were primed with different concentrations of sodium silicate (0, 10, 20, and 30 g L⁻1) for 12 h and then subjected to drought stress at –0.12 MPa using polyethylene glycol (PEG-6000). Results showed that drought significantly reduced germination percentage, seedling growth, and biomass accumulation. However, seed priming with 20 g L⁻1 Si markedly improved seedling performance under drought stress. Compared to the non-primed control, this treatment increased germination percentage by 127%, shoot length by 139%, root dry weight by 102%, and seedling vigor index (SVI) by 362%. These results demonstrate that seed priming with 20 gL⁻1 Si is highly effective in enhancing drought tolerance in maize. These enhancements were associated with improved water uptake, greater shoot and root elongation, and enhanced dry matter accumulation. This study highlights the effectiveness of silicon seed priming as a simple, low-cost, and sustainable strategy to improve maize seedling establishment and early drought toleranceespecially relevant for scarce water regions and climate-resilient agriculture.
