초록

본 연구는 4개 산지(유고슬라비아, 이탈리아, 영국, 불가리아)의 24년생 글루티노사오리나무를 대상으로 종압축 및 휨강도 특성을 규명하고, 또한 이들을 생장속도(평균연륜폭)와의 관계도 규명하였다. 압축강도는 $231{\sim}326kgf/cm^2$의 범위였고, 산지 간 차이를 보였다. 세 개 산지는 생장이 좋을수록 압축강도 및 압축영계수는 저하되는 것으로 나타났으나, Yugoslavia산지는 생장이 가장 좋으면서도 가장 높은 강도 값을 나타냈다. 휨강도는 $426{\sim}727kgf/cm^2$의 범위였고, 산지 간 차이가 있었다. 휨강도는 생장이 좋을수록 강도 및 영계수가 커지는 것으로 나타났다. 종자 산지가 다른 글루티노사오리나무 중 유고슬라비아산이 좋은 수고생장과, 다른 산지의 약 2배의 흉고직경을 나타내며, 압축, 휨강도에서도 가장 우수하여 생장과 재질면을 고려했을 때 현시점에서 가장 우수한 품종으로 판단된다.

Relationship between growth rate and wood quality was investigated by mechanical properties with Alnus glutinosa L. (24 years old) from 4 different origins of seeds (Bulgary, Italy, United Kingdom and Yugoslavia). Compression strength was in the range of $231{\sim}326kgf/cm^2$, and there was some differences among different origins of seed. Wood cultivated from the seeds of Italy, United Kingdom, and Bulgary showed higher growth rate and had lower compression strength and compression young's modulus. Wood from Yugoslavia seed had the fastest growth rate with higher strength than other three origins of seed. Bending strength was in the range of $426{\sim}727kgf/cm^2$, and there was some differences among the origin of seed. Higher growth rate wood showed higher bending strength and young's modulus than other woods. Trees cultivated from Yugoslavia seed had two times in diameter than other different origins of seeds, also have compressive strength, bending strength than other origins, which can be recommended as best cultivar in Alnus glutinosa L.
