Abstract
This study was carried out to investigate the check shelling distribution of Lindera erythrocarpa Makino in Kanghwa Island, MT. Suri, Kyunggido and MT. Kaya, Chungchongnamdo. The results were as follows : The total distribution area of Linedra erythrocarpa where are Jeondeung temple and Jugsu temple Kanghwa Island, MT. Suri, Kyunggido and MT. Kaya, Chungchongnamdo was 344.4ha and the total number of Linedra erythrocarpa was 3,224. The total number of femle Linedra erythrocarpa was625(22.2%) except the seedlings under 2cm of DBH(Diameter breast of height). For the estimation of tree age by counting of tree rings, the regression equation was Y=1.79X+9.47($R^2$=0.83, DBH=cm). The soil acidity of stands studied was $pH4.6{\sim}pH5.8$. And the soil acidity of Seoul was $pH4.2{\sim}pH4.5$ So for the Planting Linedra erythrocarpa in Seoul area, the soil acidity of planting area should be changed to $pH4.6{\sim}pH5.8$. The flower size of and female of Linedra erythrocarpa was 5.96mm, 3.66mm, respectively. The length of petiole of male and female of Linedra erythrocarpa was 5.96mm, 3.66mm, respectively. The length of petiole of male and female of Linedra erythrocarpa was 5.96mm, 3.66mm, respectively. And the number of flowers per flowering bud of male and female were 13.4, 11.2, respectively. The flowering period of Lindera erythrocarpa in Suwon was 21 days from May 2 to May 22. And The leaf continuing period of Lindera erythrocarpa in Suwon was 203 days from April 7 to October 27. And the fall-foliage color continuing period was 10 days from October 18 to October 27. The fruit continuing period of Lindera erythrocarpa in Suwon was 61 days from September 26 to November 26.
