Don) canopy for a full year. The photosynthetic capacity and needle N content in various layers of the canopy were measured every month. Temporal variations in photosynthetic capacity and needle N content expressed on a projected-area basis (P-area, N-area) were similar. Furthermore, both P-area and N-area decreased with increasing depth from the top of the canopy on each sampling date. As a consequence, a significant correlation was observed between N-area and P-area. Temporal variations in photosynthetic capacity and needle N content expressed on a mass basis (P-mass, N-mass) were also similar. P-mass also decreased with increasing canopy depth. However, in contrast to N-area, there was only a slight decrease in N-mass with increasing canopy depth. Hence, the correlation between N-mass and P-mass was lower than the projected-area value. Because N-area was highly correlated with the needle mass per projected-area (NMA), the spatial variation in N-area (and therefore P-area) in the canopy is attributed to the variation in NMA, which decreases as the depth from the top of the canopy increases. Furthermore, the slope of the linear regression between N-area and NMA differed between sampling dates, indicating that the temporal variations in N-area (and therefore P-area) are strongly influenced by N-mass. For most of the sampling dates, a linear regression between N-area and P-area tends to converge into a single line segment. However, on several sampling dates, there was a pronounced decline in P-area below this line segment. This reduction in P-area, which does not accompany a reduction in Narea, seems to be attributable to stomatal limitations induced by the low soil temperature in winter and early spring.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"PHOTOSYNTHETICA. 48(2): 249-249(2010)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"Kobayashi, H","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.ZNfCgUfp.html"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"SPRINGER"}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1007/s11099-010-0031-6"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1007/s11099-010-0031-6","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0300-3604","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00773340","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kobayashi,  H"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inoue,  S"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Gyokusen,  K"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-25"}],"displaytype":"detail","filename":"Spatial_temporal_variations_photosynthesis-nitrogen.pdf","filesize":[{"value":"4.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Spatial_temporal_variations_photosynthesis-nitrogen.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/10307/files/Spatial_temporal_variations_photosynthesis-nitrogen.pdf"},"version_id":"3cddb460-31de-4885-a3a4-e32c7797a4d7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"canopy nitrogen distribution","subitem_subject_scheme":"Other"},{"subitem_subject":"light environment","subitem_subject_scheme":"Other"},{"subitem_subject":"needle development","subitem_subject_scheme":"Other"},{"subitem_subject":"photosynthetic capacity","subitem_subject_scheme":"Other"},{"subitem_subject":"winter depression","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Spatial and temporal variations in the photosynthesis-nitrogen relationship in a Japanese cedar (Cryptomeria japonica D.
