This study was performed to identify optimal harvesting time of ginseng seeds and to examine the effect ofGA₃ treatment for improvement of seed stratification rate. Ginseng seeds harvested from Land race, Chunpoong and Yunpoongcultivar in July 20 were tested for stratification rate. It was shown that stratification rates of land race, Yunpoong andChunpoong cultivar were 94.1%, 93.1%, and 82.6%, respectively. Seeds of Chunpoong cultivar harvested 10-15 days latershowed a comparable stratification rate to that of Land race, indicating that late harvest of Chunpoong seeds is beneficialfor the increase of stratification rate. The higher stratification rate was found in mature seeds (92.3%) than immature seeds(37.8%), both of which were harvested in July 20. Stratification rate of mature seeds harvested in July 15 was 87.5%, demonstratingoptimal harvesting time of ginseng seeds with higher stratification rate is after mid-July. An exponential growthof endosperms of ginseng seeds was observed from early June to mid-June and then slow growth was observed. There wasno obvious growth of embryos from fertilization to mid-August. After the this time, embryos quickly grew until late October.
Thus, appropriate stratification control is essential during the period (from early September to late October) in order tooptimize embryo growth and development. While no increase of stratification rate was observed in seeds treated with50 ppm of GA₃, significant increases were observed in seeds treated with 100 ppm of GA₃. At this concentration of GA₃, thestratification rate of Land race, Chunpoong and Yunpoong cultivar was 95.0%, 95.3%, and 96.5%, respectively.
