Abstract
Growth characters such as height, DBH, crown width, branch length and branch diameter were measured from 23 clones of plus trees of Pinus koraiensis. The results were as follows; 1) Differences between the largest and smallest clones were amounted to 41% in height, 81% in DBH, 50% in crown width, 55% in branch length and 83% in branch diameter. 2) There were significant differences between clones in every growth characters and correlation coefficients between growth characters were positive and significant (
잣나무 수형목(秀型木) 23클론에 대(對)한 수고(樹高), 흉고직경(胸高直徑), 수관폭(樹冠幅), 가지길이 및 가지 직경(直徑)의 생장특성(生長特性)을 측정(測定)하여 다음과 같은 결과(結果)을 얻었다. 1) 생장(生長)이 가장 우수(優秀)한 클론은 가장 불량(不良)한 클론에 비(比)하여 수고(樹高)는 41%, 흉고직경(胸高直徑)은 81%, 수관폭(樹冠幅)은 50%, 가지길이는 55% 및 가지직경(直徑)은 83%의 양호(良好)한 생장(生長)을 보였다. 2) 각(各) 생장특성(生長特性)은 클론간(間)에 유의차(有意差)가 있었으며, 각(各) 생장특성간(生長特性間)의 상관(相關)은 고도(高度)의 정(正)의 상관(相關)을 나타냈다 (
