説明

Global warming has encouraged farmers to start planting earlier. However, these advanced plantings also increase the risk by low-temperature stress. Therefore, accelerated germination under low-temperature conditions and enhanced chilling stress tolerance of seedlings are important factors to increase crop production. Here we show that a single seed treatment using a mixture of hydrogen peroxide (H2O2) and a trace amount of transitional metal catalyst can accelerate germination under cool temperature conditions. When seeds were germinated at 23ºC or 11ºC in the dark, the treated seeds germinated earlier than the control seeds. Furthermore, the treatment was effective long after germination: seedlings from the treated seeds showed faster root growth at both 23ºC and 11ºC. This treatment could provide a sustainable method to improve growth performance under both optimum and chilling conditions.
