On the Variation of Fiber Tissues of the Paper Mulbery in Korea

닥나무 섬유(纖維)의 변이(變異)에 대하여

This study was carried out to investigate the variation of fiber tissues of some paper mulberies (Broussnetia kazinoki Sieb.). Every twig was selected for variation from 1 year old to 4 years old of the paper mulberies growing in Woensung, Bounghwa, Euiryung and Wanju in Korea. The results are summarized as follows: 1. The length and the width of fiber tissue increase to old twigs. 2. In primary fiber tissue the variation of length increases considerably slowly, but on the contrary that of width increases very rapidly. 3. In the secondary fiber tissue the variation of length increases comparatively rapidly but that of width does not. 4. In order to investigate the fact shown from the contrary results on the fiber length and width between primary and secondary fibers, the authors calculated the correlation, coefficient and the results show comparatively higher possitive correlation coefficient.

닥나무의 일년지(一年枝)부터 사년지(四年枝)에 이르기까지 섬유장(纖維長)과 그 폭(幅)의 변이(變異)와 섬유장(纖維長)과 폭(幅)과의 관계를 조사한바 일반적으로 고지(古枝)로 갈수록 섬유장(纖維長)과 폭(幅)은 증가 되었으며, 일차섬유(一次纖維)에서는 섬유장(纖維長)의 변이(變異)는 극히 완만한데 비하여 섬유폭(纖維幅)의 변이(變異)가 급격하였다. 그러나 이차섬유(二次纖維)에서는 이와 반대의 현상을 보여주었는데 이들 상호간(相互間)에는 비교적 높은 정(正)의 상관관계(相關關係)가 있었다.
