Physiological and ecological comparison of boxthorn cultivars grown in southern and central regions of Korea

This experiment was conducted to compare the fruit yield and quality of the boxthorn(Lycium chinese Mill.) landraces grown in the northern and southern regions. The ripening stage of northern landraces was four to seven days earlier as compared with sonthern landraces. The northern landraces had better for agronomic characters including stem lenth and diameter than the southern landraces, and had small and dark green leaves,and Sharp thorns,but the southern ones had large and light green leaves. Haenam landrace had not thorns. The northern landraces were more susceptable to antracnose than the southern one, and there was no difference in mite resistance between the landraces. The phe photosynthesis abilityof northern landraces were higher than that of southern ones at early growth stage(by mid-June), but vice versa after early Juld. The northern landraces had much more dryweight and leat area than the southern ones. It was assumed that the differences among landraces were mostly due to the characteristis of each landrace rather than due to the regions where each landrace had been grown. The extract content of Kwangju iandraec was higher than that of Daejeon landrace. The higher amount of extracts of the Kwangju landrace might be due to the daily high temperature and more sunshine in the Kwangju area.
