Released strains on the surface of xylem of a 65-years-old Keyaki (Zelkova serrata Makino) were measured. Then, longitudinal Young’s modulus and longitudinal shrinkage of the wood specimen, which sampled away from nearby each measuring point of the released strain, form nearby each measuring point of the released strain, were determined. And, the ratio of gelatinous layers in the wood fiber domain were counted under the observation using fiber domain were counted under the observation using an optical microscope. Then, physical properties of the gelatinous layer were estimated by using the law of mixture. As the result, it was revealed that (1) the longitudinal Young’s modulus of the gelatinous layer is 1.46 times larger or more, (2) the released strain is 23.6 times larger, (3) the longitudinal shrinkage is 30.8 times higher than that of the lignified layer. It is concluded that the origin of the physical properties peculiar to the tension wood is attributable to the physical properties of the gelatinous layer.

生材状態でのゼラチン層の軸方向ヤング率は木化層の1.46倍もしくはそれ以上である。(2) 軸方向成長応力解放ひずみは木化層の23.6倍に達する。(3) 軸方向収縮率は木化層の30.8倍になる。以上は引張あて材にみられる種々の特異な物性はゼラチン層の性質によるものであることを示している。", "subitem_description_language": "ja",
