영문 초록

Ginseng (Panax ginseng C.A. Meyer) is a perennial plant and propagates by seeds, and those need after-ripening for germination. To be ready for climate change and to ensure a stable seed supply, the technique for storing seeds in short-term and long-term in large quantities is required. In this study, dehisced ginseng seeds from two locations, batch #1 and batch #2, were stored at -3.5℃ with different moisture content, and after 3, 15, and 27 months of storage, the percentage of radicle emergence and shoot emergence were measured. After 3 months, radicle emergence and shoot emergence were normal only when the seed moisture content was more than 35%, and overall, germination was higher in batch #2 than in batch #1. After 15 months, the partially dehydrated seeds, with a moisture content between 45 to 54%, showed the highest germination rates, and most of the undried seeds were spoiled and failed to germinate. Seeds with moisture content lower than 25% had poor germination, too. The partially dehydrated seeds also succeeded in germination and growth in the soil after 15 months of storage, but deteriorated after one more 1 year, too. In summary, ginseng seeds look like have temperate recalcitrant seed characteristics, and partial dehydration allows extension of seed longevity.
