As this result agrees with that obtained by measurement of tracheid length which becomes constant from 10th annual ring, it can be considered that juvenile wood zone of these Sugi is from pith to 10th annual ring and adult wood zone is from 10th annual ring to cambium. 2) From the results of compressive and bending tests, we observed considerable differences between these Sugi grown in Okinawa and those grown on other prefectures on \u03c3c/Ec and \u03c3b/Eb. That is, the values of \u03c3c/Ec and \u03c3b/Eb of Ji-sugi and introduced Seedlingsugi were higher than those of other Sugi. Furthermore, we found that though there was no differences in these values between Ji-sugi and introduced Seedling-sugi, these values of juvenile wood of these Sugi were higher than those of adult wood as shown in Table 2 and 3. 3) On Ji-sugi and introduced Seedling-sugi, specific gravity showed high correlation to compressive strength and modulus of rupture, but it showed low correlation to Young\u0027s modulus in compression and bending.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]}, "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/20.500.12000/4311"}]}, "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": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
