Environmental Characteristics of Abies koreana Stand on Mt. Halla
pp.5-9
To identify factors affecting the regeneration of Abies koreana, we examined environmental conditions on Mt. Halla. In three seedbed types (Sasa site, shade by rock, forest floor), we investigated temperature and soil moisture content. Stratified A. koreana seeds were placed on each seedbed types and counted germinated seedlings. Snow cover period in north-facing slope, 102±17 days, was significantly longer than that of southfacing slope, 94±14 days. Average temperature of May to July, the period of seed germination, was significantly lower in forest floor than around rocks and under Sasa quelpaertensis. Germination rate of on each seedbed types was not different. This study suggests that the proper environmental conditions of A. koreana's regeneration may be affected on more complex factors.
