    This study was carried out in order to investigate the early growth and root development characteristics ofPeucedanum japonicum container seedlings. The experiment was performed by containers (128 and 200 cavities containers)and shading levels (0%, 35%, 50% and 75% shading). Germination rate of P. japonicum seeds was getting higher in thelower shading level and the highest in the full sunlight (71.9%). Plant height was the highest under 50% shading of allcontainers. Fresh weight and dry weight of the shoot (leaves + stem) were the highest under 50% shading of all containers,too. Meanwhile, fresh weight and dry weight of the root per plant were the highest under the full sunlight of 128 cavitiescontainer such as 0.34 g and 0.03 g, respectively. Total root length, root project area and root surface area were higher underthe full sunlight of 128 cavities container such as 234.5 ㎝, 6.6 ㎠ and 20.8 ㎠, respectively and the next higher was under35% shading such as 201.7 ㎝, 5.9 ㎠ and 18.4 ㎠, respectively. A case of root volume was the highest with 0.15 ㎤ under thefull sunlight. As a result of the surveying the whole experiment, it is concluded that the shoot and root of P. japonicum seedlinggrow nicely by maintaining 35% shading.
