Plant sample is digested by Kjeldahl digestion method using H2SO4 and H2O2, and an aliquot of digested solution including ammonium nitrogen (about 2μgN) is directly taken into a Pyrex glass tube with the outer diameter 4mm. After water in the Pyrex tubes is evaporated, the glass tubes are evacuated by the vacuum system for discharge tube preparation and sealed with oxidation reagent (CuO) and water absorbent (heated CaO at 950℃). The sealed tubes are heated at 560℃　for 30 min in a muffle furnace to oxidize ammonium into N2 gas. The 15N abundance can be measured by emission spectrometry (JASCO N-150 analyzer). This procedure is the simplest and accurate method for the determination of 15N abundance of total N in the samples.ケルダール分解液を直接パイレックスガラス管に導入して放電管を作成し、発光分光法により15N濃度を測定することができた。植物試料を硫酸-過酸化水素を用いてケルダール分解し、一定量に定容後、インドフェノール法でアンモニウム濃度を測定した。測定後、窒素として約2μg程度を含む分解液を直接片側を閉じた外径4mmのパイレックスガラス管に入れ、水を減圧除去した後、酸化剤(線状酸化銅)と水吸収剤(950℃で加熱した酸化カルシウム)を入れて、真空封印した後、560℃で30分間加熱して、アンモニアを窒素ガス変えた。15N濃度は、発光分光法(JASCO N-150アナライザー)で分析した。この方法は、従来の方法と比較して試料全窒素の15N濃度を測定するには最も簡単で正確である。","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"52","nameIdentifierScheme":"WEKO"}],"names":[{"name":"大山,
