The objective of this study was to investigate the response of seed germination based on seed treatment of supercritical carbon dioxide (SC-CO2) sterilization. Seeds of eleven species were treated with SC-CO2 at 150 bar, 55℃ and 15 min (condition of fungi sterilization). Standard germination tests were used to evaluate germinability of seeds. Compared with non-treated seeds, SC-CO2 treatment caused significant variation of germination rate in different species. Different species showed different response to SC-CO2 treatment. The results suggest that crop of Leguminosae family is suitable for SC-CO2 sterilization.
