Abstract
본 연구는 4개 종자산지(Yugoslovia, ltaly, United Kingdom, Bulgaria)의 글로티노사오리나무(Alnus glutinosa)를 대상으로 목섬유 길이, 도관 길이 및 직경인 해부학적 성질을 조사하여, 이들의 종자산지 간 및 생장속도와의 관계를 규명하였다. 글로티노사오리나무는 산공재, 계단상천공, 교호상벽공으로 나타났다. 접선단면에서 방사조직 높이는 9~11, 횡단면에서 방사조직 수는 16~26개로 나타났다. 산지 간의 목섬유 길이, 도관 길이 및 직경에서 만재부에서는 차이가 없었고, 조재부에서는 차이가 있는 것으로 나타났다. 3개 산지는 생장이 좋을수록 만재부의 목섬유 및 도관 길이가 짧아지는 것으로 나타났으나, 유고슬로비아산은 생장이 좋으면서 목섬유 및 도관길이도 긴 것으로 나타났다. In this study, relationship between seed origin and growth rate of Alnus glutinosa from different seed collection (Yugoslovia, ltaly, United Kingdom, Bulgaria) was investigated with focused on anatomical properties as wood fiber length, vessel element length and diameter. Alnus glutinosa showed diffuse-porous wood with scalariform perforation in alternate pitting. Ray height was 9~11 in tangential section and ray number were 16~26 in cross section. There were no differences on latewood focused on wood fiber length, length and diameter of vessel element, but difference on earlywood. Other than Yugoslavian seed, there was better growth rate with shorter wood fiber and vessel element length on latewood. However, seed from Yugoslovain showed better growth rate with longer wood fiber and vessel element length than other 3 seed orgins.
