Background : In this study, We will compare germination rate for each bed soil moisture content and find optimal seed germination on bed soil condition. This study was carried out germination efficiency related percent germination, germination energy, mean germination time and germination seed treated bed soil moisture content by volume on dehisced Korean ginseng seeds.
Methods and Results : This study was used for conventional seeds of dehisced Korean ginseng seeds. In order to bed soil moisture treatment, We was dried on the soil until 1.5% moisture content and treated 12 different bed soil, soil 100 g volume up water 10 ㎖ for 10% soil moisture content, that contain moisture content (1.5 - 59.66%) at intervals 5 - 10% moisture content in Wagner ports. For bed soil moisture content test, We was sowed 61 Korean ginseng seeds each port on 18-May. In order to maintain the moisture content, The top of the port was covered with vinyl for blocked from the outside air. After sowing seeds, We was examined the germination rate, germination strength (GS), mean days per germination (MDG), and germination speed (GR) at every two days. Our results showed that germination rate was 94.5% at 47.07% moisture content. It had over 90 percent germination rate from 40.90 to 59.96% moisture content. High germination rate treatments also was higher with another traits such as germination strength (GS), mean days per germination (MDG), and germination speed (GR).
Conclusion : The germination rate is very important in Korean ginseng cultivation of direct sowing. The soil moisture content is one of the most important environment related germination rate of ginseng seeds. According to our result, 40.90 to 59.96% bed soil moisture content had over 90 percent germination rate. These finding could be used to increase high germination rate, is required to proper irrigation. We will need to proper moisture content to increase high germination rate not only bed soil but also soil.
