Trends of Fibril Angle Variation in Pinus koraiensis Sieb. et Zucc. <Jour. Kor. For. Soc. 46:44-52 1980> Corresponding author Jin-Heon Kwon kwon@kangwon.ac.kr
The purpose of this study was carried out to examine the systematic trends in fibril angle which existed within the trunk of Pinus koraiensis. The authors tried a simple method (Yaichi kobayashi method) of demonstrating the fibrillar orientation in lignified walls in which Schulze's reagent was used. The results were summarized as follows. 1) Fibril angles were greater for earlywood(avg. 23.38°) than for latewood(avg. 17.85°). 2) The average fibril angles of consecutive rings decreased consistently and markedly from pith to bark. 3) Differences of the fibril angle between in springwood and in summerwood were greater in corewood than in middle or outerwood.
