The results obtained are as follows : 1) Although PEG content was independent of molecular weights with a few exceptions, it increased linearly with an increase in concentration of PEG aqueous solution (Figs. 1 and 2). 2) The bulking ratio became almost constant when PEG content reached 45 percent for Katsura and 50 percent for sitka spruce under a concentration of 30 percent. It was recognized from this fact that the cell wall was saturated with PEG molecules (Figs. 2 and 3). 3) With minor exceptions in R-direction of Katsura, bulking ratio increased almost linearly with decreasing molecular weight under the same concentration of PEG solution. However, the tendency with the variation of concentration was different between both species or the structural direction even in the same molecular weight (Fig. 4). 4) In all cases of T-and R-directions for both species, the linear relationship was given between ASE and bulking ratio (Fig. 5). 5) In both T-and R-directions for sitka spruce, the values of ASE increased with decreasing molecular weight and increasing concentration of PEG solution, and the value of ASE was nearly 100 percent above a concentration of 20 percent in PEG-400,and above 30 percent in PEG-600 (Table 1,Fig. 6). 6) In the case of Katsura, the values of ASE were slightly different between T- and R-directions with molecular weights and concentrations of PEG, but the value reached 95 to 98 percent above a concentration of 30 percent in PEG-400 (Table 2,Fig. 7).","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00062275","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00757373","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"福山, 萬治郎","creatorNameLang":"ja"},{"creatorName":"フクヤマ, マンジロウ","creatorNameLang":"ja-Kana"},{"creatorName":"Fukuyama, Manjiro","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"浦上, 弘幸","creatorNameLang":"ja"},{"creatorName":"ウラカミ, ヒロユキ","creatorNameLang":"ja-Kana"},{"creatorName":"Urakami, Hiroyuki","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000079101.pdf","filesize":[{"value":"603.6 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000079101.pdf","url":"https://kpu.repo.nii.ac.jp/record/5102/files/KJ00000079101.pdf"},"version_id":"c806bc48-4a36-4925-9c9c-60770321e322"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper"}]},"item_title":"ポリエチレングリコール処理木材の寸法安定性(林学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ポリエチレングリコール処理木材の寸法安定性(林学部門)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["427"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"5102","relation_version_is_last":true,"title":["ポリエチレングリコール処理木材の寸法安定性(林学部門)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-04-12T05:05:40.149712+00:00"}
