New shoot growth of Panax ginseng root was investigated comparing with burley and soybean from l0$^{circ}C$ to 30$^{circ}C$ under dark. Shoot growth ceased by 12days at 30$^{circ}C$ and optimum temperature appeared to be 15$^{circ}C$/20$^{circ}C$ (15hrs/9 hrs) , and 15$^{circ}C$/15$^{circ}C$ for ginseng. Shoot growth seems to be Poor below l0$^{circ}C$. Temperature for maximum growth 20$^{circ}C$/20$^{circ}C$ for barley and 20$^{circ}C$ /25$^{circ}C$ for soybean. Barley did not germinate above 25$^{circ}C$/25$^{circ}C$, but grow better than soybean below 15$^{circ}C$/25$^{circ}C$. Fresh weight of 2 weeks suggesting cessation of water uptake at higher temporal use. Ginseng showed greater root ply s shoot of ginseng was linearly increased at 15$^{circ}C$ but did not increased at 25$^{circ}C$ after occurence of die-back of new shoot or root rot above 25$^{circ}C$.
