The aim of this study was to establish a cryopreservation protocol for Korean ginseng seeds. Desiccation of undehisced ginseng seeds to a moisture content (MC) of 7.1 % did not decrease their dehiscence and germination. After cryopreservation, the dehiscence percentage of desiccated seeds decreased for MC above 12.5%; it was 26% for 22.6% seed MC and nil for 41.9% seed MC. Germination percentage did not decrease significantly between 12.5-22.6% seed MC, while germination percentage of dehisced seeds decreased below 7.2% MC, reaching 25.8% at 3.8% MC. After cryopreservation, the germination percentage decreased from 90.5-92.9% at 8.3-10.6% MC to 84.8% at 12.5% MC. At MCs below 8.3%, germination rapidly decreased from 85.0% at 7.2% MC to 34.9% at 5.3% MC. Therefore, the hydration window for cryopreservation of ginseng seeds is around 8-11% MC. Undehisced Korean ginseng seeds were characterized by their high lipid and protein content (lipids, 42.6% FW; proteins, 41.0% FW). When using thermal analysis, during the cooling phase, exothermic ice crystallization peaks were observed with dehisced ginseng seeds above 13.5% MCs (3.3 J g(-1) FW). A second crystallization peak was detected following ice crystallization peaks. specialized After-ripening Desiccation Germination Panax ginseng ca meyer 076 29 5 419-426 2008 0143-2044 https://www.documentation.ird.fr/hor/PAR00003124 0143-2044 https://www.documentation.ird.fr/hor/PAR00003124 IRD - Base Horizon / Pleins textes 2009-01-09 2017-08-23 PAR00003124 fre
