초록

The purpose of this study is to provide basic data for sustainable production by investigating the growth characteristics of the endangered Korean fir (Abies koreana) under shading treatments. It was found that there was a temperature difference of approximately 6℃ between the shading treatment and the control group, and a difference of about 13% in soil moisture content. Only in the shading treatment group did dead individuals of Korean fir appear, and it was confirmed that other individuals also suffered from leaf withering and other physiological damage. The growth response of root diameter was observed in T2, and the growth of seedling height was observed in T3, indicating that satisfactory growth was observed in over 50% of the shading treatment groups. Total Chlrolophyll was higher according to the shading treatment(p<0.05), This trend is thought to be due to the short-term nature of the experiment, and it is expected that statistical significance will be observed after long-term adaptation. It is considered that over 50% shading effect will be beneficial for survival and growth in Abies koreana over 5 years old at the seedling stage.
