Background : This study was conducted to determine the impact of temperature elevated and the effect of transplanting times based on climate change scenario on growth of 2-year-old korean ginseng (Panax ginseng C. A. Meyer.) in temperature gradient chambers (TGC). Methods and Results : As a plant materials, ‘Yunpoong’ was cultivated in TGC at ambient temperature(Amb), Amb+2℃, Amb+4℃ and Amb+6℃ respectively. Ginseng was also transplanted on March 29, April 12 and 26 respectively. Investigation on characteristic of aerial parts were carried out on 28, 56, 84 and 112 days after transplanting and characteristic of roots were conducted on October 19. As transplanting time was faster and temperature was higher, the growth of aerial parts were increased. Compared with those of ginseng transplanted on March 29 with Amb, the root weight which tend to decrease depending on late transplanting time and high temperature decreased about 11.1%, 35.4% and 42.4% in Amb+ 2℃, Amb+4℃ and Amb+6℃ respectively. Ginseng transplanted on April 12 and 26 decreased about 20.9%, 33.9% respectively. Conclusion : Consequently, the more transplanting time extend, the more quantity increased in all temperature treatment. So, it is possible to increase in quantity to advance transplanting time although high temperature will be caused by the climate change.
