이광남,차경수 ( Kwang Nam Lee,Gyung Soo Cha ) 한국산림과학회 1987 한국산림과학회지 Vol.76 No.4
The research was carried out to investigate the related phenomena, the latent structures and synfhetical characteristics in various growth factors of Phyllostachys bambusoides Sieb. et Zucc. growing at Damyang gun, Chollanamdo, using multivariate analysis. 1. By synthetical characteristics in canonical correlation between height-growth factor group and diameter-growth factor group, the former was determined by the culm height (x₁), and the latter by the. diameter of the largest internode(x_7). And for those between quantitative growth factor group and qualitative growth factor group, the former was determined by the surface area(x_(10)), and the latter by the diameter of the largest internode (x_7). 2. The ten growth factors of bamboo culm were simplified by two principal components on the basis of accumulated proportion aimed at 90%. The first principal component(Z₁) as a $quot;size factor$quot; showed high correlation with growth factors except eye-height diameter(x_5). The second principal component (Z₂) as a $quot;shape factor$quot; showed high correlation only with x_5. 3. The bamboo culm, and the latent phenomenon between their growth factors could be determined by two common factors showing high communality(94.16%). The ten growth factors can be grouped into two attribute factors: quantity and quality. 4. The bamboo culms can be classified into five types: total, volume, shape-quality, inferior and middle.
