The relationship between occurrence of a slip plane and stress would give fundamental informations on the failure process of wood. In this article, it was discusseed the relationship between the type, the position, number of a slip plane and stress. It was used a polarized microscope to detect slip planes of SUGI wood (Cryptomeria japonica) and the obtained results may be summarized as follows. 1. In the elastic range of wood, a compression stress produced slip planes more frequent in early wood than in late wood. In the plastic range, a compression stress produced slip planes more frequent in late wood than in early wood. 2. At early wood in tangential section and late wood in radial section, a slip plane was produced at the tracheid walls contact with a ray in elastic range. But in plastic range, a slip plane was produced at tracheid walls in contact with a ray and out of contact with a ray. 3. A slip plane of late wood tracheid was produced more frequent in tangential section than in radial section. 4. A slip plane of single wall type was produced at lower stress level then a slip plane of double wall type. 5. At same stress level, the location and the number of a slip plane varied with a section and a position in one growth ring.", "subitem_description_type": "Other"}, {"subitem_description": "紀要論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球大学農学部"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/3896"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "琉球大学農学部学術報告"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
