초록

The effect of the surrounding vegetation on the seed germination and growth of mountain-cultivated ginseng (MCG, Panax ginsengC.A. Meyer) was investigated. Seed germination rate and growth were tested for allelopathy effects on four forest tree species aftertreatment with fallen leaves and leaf extracts. In the case of soil treatment through fallen leaves and crushed leaves, the germinationrate was lower in the Quercus myrsinifolia treatments, and the average germination time was slower when Chamaecyparis obtusa wastreated. In the case of Pinus densiflora and Quercus variabilis, which are used in most of the MCG cultivation areas, they did nothave a significant effect on seed germination. In the fallen leaves treatments, the stem showed a tendency to lengthen. The hot waterextract treatment showed a higher germination percentage than the cold water extract treatment. The extract treatment showed a deficientgermination percentage of some MCG seeds. However, in the case of the treatments except for this, the germination percentage wassimilar to that of the control treatment. However, the Mean Germination Time, germination rate, and germination value were fasterand higher than the control treatment. As a result of calculating the allelopathic index (AI) of MCG according to the extract treatmentof 4 species, most had a negative effect on germination, and P. densiflora and Q. variabilis extracts showed the most significant effect. The ginsenoside content was higher in the fallen leaves treatment than in the control. The above results will help select and manageMCG plantations.
