This study was conducted to investigate the effects of temperature and shade, which are basic environmental conditions, on growth, yield, inorganic components, and general components of Codonopsis lanceolata, in order to obtain basic data for improving yield capacity. In natural light, in the 15, 20, and 25°C groups, the plant heights ranged between 218.9 cm and 223.9 cm, and there was no significant difference between groups. However, the leaf size was larger in shade, and the leaf area was significantly larger in the 15 and 30°C groups. In natural light, root length and diameter were shorter and thinner when the temperature was higher, and growth was highly suppressed at 30°C. With regards to macroelements, the contents of Na, Mg, and P increased as temperature increased, regardless of the plant part; however, no constant tendency was observed in K and Ca according to temperature. The contents of Mg and Ca (from highest to lowest) were in the order leaf>stem>root, whereas the contents of Na, P, and K were in the order stem>leaf>root. Contents of general components varied according to temperature, and were highest at 30°C. While the plant height was increased under the constant 25°C +DIF (Difference between day and night temperature) condition, growth was suppressed in the –DIF group, in which the night temperature was higher than the day temperature, which suggests that a change in night temperature is one of the factors that affects the growth of C. lanceolata. As in the growth of the above-ground parts, fresh weight of the root was high in the constant 25°C group and +DIF group. Notably, it was more than 2.5 times the fresh weights in the constant 15°C group, constant 20°C group, and –15 DIF group.
