Abstract

Relationship between annual ring width and physical properties of 24-year old alder woods (Alnus glutinosa L.) that had different seed origins from four provenances such as Bulgary, Italy, United Kindom, and Yugoslavia was investigated. No difference among different origins of seeds was found for the moisture content, density, and shrinkage or tangential radial (T/R) ratio. These properties had also no relationship with the growth rate. As important parameters among wood quality indices, no difference in the density or shrinkage on wood that has different growth rates was detected among alder woods from four different origins of seeds. Therefore, it is considered that higher growth rate might be a key factor for selecting the seed origin of the alder tree.

본 연구는 4개 종자산지(Yugoslavia, Italy, United Kingdom, Bulgary)의 글루티노사오리나무(24년생)를 대상으로 물리적 특성을 조사하여 생장(평균연륜폭)과 목재의 재질관계를 규명하였다. 함수율, 밀도, 수축률 및 T/R비는 모두 산지간에 차이가 없었다. 또한 이런 성질들은 생장과도 관계가 없는 것으로 나타났다. 종자산지가 다른 글루티노사오리나무의 중요한 재질지표인 밀도와 수축률의 경우, 생장의 차이에 따라 밀도와 수축률이 차이가 거의 없는 것으로 나타나, 생장이 우수한 것이 우수품종의 기준일 것으로 생각된다.
