• Label: Leaf xylem stable nitrogen isotope composition (delta15N)
• Entity URI: https://w3id.org/APD/traits/trait_0003052
• Type: numeric
• Definition: Nitrogen stable isotope ratio [ECSO:00001737], d15N [ECSO:00001738], of xylem sap [PO:0025539] from leaf [PO:0025034] xylem vessels [PO:0025417].;Nitrogen stable isotope ratio, d15N, of xylem sap from leaf xylem vessels.
• Additional comments: delta15N is calculated as the ratio of, 15N/14N in a sample to 15N/14N in a standard, minus 1. The result is expressed in parts per thousand, commonly referred to as per mille. A lower value for delta15N indicates the sample has a lower ratio of 15N/14N relative to the standard.
• units: {delta}[ppth]
• allowable range: -25 - 75 {delta}[ppth]
