年輪年代法体験学習の教材を得るため,アラスカ州から輸入されたスプルース材の樹種同定と年代決定および産地推定を行なった.木材解剖学的特徴に基づく同定の結果,樹種はシトカスプルースに同定された.年輪年代解析の結果,15試料からAD1689–1990にわたる302年間の標準年輪曲線(AKNCCH01と命名) が得られた.AKNCCH01は,アラスカ南東部沿岸地域の標準年輪曲線とtBP > 6.5を示し,特にプリンスオブウェールズ島のものとtBP = 9.36という非常に高い値を示した.以上の結果は,これらの輸入スプルース材が,アラスカ南東部太平洋沿岸諸島で,17世紀末~現代にかけて生育したシトカスプルースであることを示唆する.
In order to obtain the teaching materials for dendrochronology workshop, wood identification, tree-ring dating and dendroprovenancing survey on imported spruce woods were carried out. As a result of identification based on wood anatomical features, the species was identified as Picea sitchensis (Bong.) Carrière (sitka spruce). A tree-ring chronology with code name AKNCCH01 (it covers AD1689–1990 from 15 woods) was obtained as a result of dendrochronological analysis. AKNCCH01 was compared with chronologies of the southeastern Alaska coastal area and yielded tBP > 6.5. In particular, correlation between AKNCCH01 and chronology of the Prince of Wales Island showed a very high value of tBP = 9.36. The above results suggest that these imported sitka spruce woods have grown at the southeastern Alaska Pacific coastal area, from the end of 17th century to the present.
