Studies on Anatomical Properties of Forsythia in Korea

한국산(韓國産) 개나리속(屬)의 해부학적(解剖學的) 성질(性質)에 관한 연구(硏究)

These experiments were carried out to investigate anatomical properties of Forsythia in Korea. The results obtained were summarized as follows: It was estimated that the vessel of cross section was almost simple pore and multiple pores which were compounded two or three units were showed sometimes and arrangement of vessel were ring porous wood. In the mean length of vessel, Forsythia koreana was ranged $539.98{\pm}154.71{\mu}$ and Forsythia ovata $602.22{\pm}157.38{\mu}$ and Forsythia nakaii T. Lee $465.50{\pm}83.02{\mu}$. In the mean length of fiber wood, Forsythia koreana $387.40{\pm}68.23{\mu}$, and Forsythia ovata was $533.90{\pm}106.77{\mu}$ and Forsythia nakaii T. Lee was $482.40{\pm}72.33{\mu}$. The type of Ray parenchyma was heterogeneous ray I tissue. The mean length of procumbent ray cell in the radial section was $42.14{\pm}8.30{\mu}$ and that of rectangle type in up right ray cell was $45.76{\pm}7.19{\mu}$ and that of square type was $26.66{\pm}2.99{\mu}$. The mean height of ray parenchyma in the tangential section was $174.80{\pm}37.51{\mu}$ and the width of ray parenchyma was $17.25{\pm}3.59{\mu}$ and the mean number of ray parenchyma was $14{\pm}3$.

우리 나라 특산(特産) 수종(樹種)인 개나리속(屬)의 해부학적(解剖學的) 성질(性質)을 조사(調査)한 결과(結果)는 다음과 같다. 횡단면상(橫斷面上)의 도관(導管)은 거의 단일도관(單一導管)이었고, 2~3개(個)로 복합(複合)된 복합도관(複合導管)도 가끔 나타나고, 도관(導管)의 배열상태(排列狀態)는 복사공성(輻射孔性) 환공재(環孔材)이었다. 도관(導管)의 평균(平均) 길이는 개나리 $539.98{\pm}154.71{\mu}$, 만리화 $602.22{\pm}157.38{\mu}$, 장수만리화 $465.50{\pm}83.02{\mu}$이었다. 목섬유(木纖維)의 평균(平均) 길이는 개나리 $387.40{\pm}68.23{\mu}$, 만리화 $533.90{\pm}106.77{\mu}$, 장수만리화 $482.40{\pm}72.33{\mu}$ 이었다. 방사조직(放射組織)의 형(型)은 이성공형(異性工型)이었다.
