林木의 年輪成長에 대한 分析 = A Study on the Growth of Annual Ring

국문 초록 (Abstract)

비교적 좋은 林木度를 維持하고 있는 58年生의 赤松과 젓나무의 混淆林에서 각각 6本의 標本木을 伐採하여 地上 0.2m의 根元部 圓板과 地上 4m마다의 圓板을 採取하여 個體別로 令階別 年輪成長을 調査하여 이들의 相關關係와 生長周期를 調査한것이다.
1. 各樹令間의 相關은 비교적 높은 相關係數로 나타나서 赤松은 20年階에서 0.7이고 잣나무에선 10年階에서 0.7이상이었다.
2. 根株年輪과 全體圓板의 年輪平均値와는 높은 相關을 나타내고 있다.
3. 赤松 個體間의 成長差異는 그 成長振幅이 큰데 反하여 젓나무의 成長은 비교적 고르게 正常的인 成長을 하고있다.
4. 年輪成長의 周期는 젓나무와 赤松間에 큰 差異없이 거의 같은 時期에 나타나고 있다.

Each six sample trees of Korean red pine(Pinus densiflora S.et.2) and Korean fir(Abies holophylla Max.) were cut at mixed forest stand of which stand density was fairly high.
Root colar disk at 0.2m above ground and the disks at every 4m above ground were collected.
The annual ring growth of the sample trees was measured by each age class.The correlation among the annual ring growth was calculated and the interval of growth period was obtained.
Following results were obtained:
1.Relatively high correlation coefficient were obtained among the growth at each age. The coefficient were above 0.7 among age class of 20 in Korean red pine and among age class of 10 in Korea fir.
2. High correlation was shown between the growth in root colar disk and in other disks.
3. Variation in annual ring growth among individual Korean red pine was high, on the other hand that of Korea fir was low.
4. Periodic growth of Korean red pine and fir appeared at some time interval.
