Wood sodium content per wood dry mass trait

Formal name:  wood sodium content per wood dry mass
Local identifier:  TOP740
Synonym Term:  wood Na content per dry mass
Related Term:  wood Na concentration
Related Term:  wood Na content
Definition:  The ratio of the quantity (SEP:quantity) of sodium (CHEBI:sodium atom) in the wood (PO:secondary xylem) to the corresponding wood (PO:secondary xylem) mass (PATO:mass) assessed after drying
Formal Unit:  mass unit / mass unit or amount unit / mass unit

Comment:  The quantity of sodium can be expressed either as a mass (with mass unit, e.g. gram) or as an amount (with amount unit, e.g. mol). The term concentration is polysemic and we suggest to not use it in this context. If possible the plant organ of wood-maesurement should be specified, i.e. stem wood or branch wood.
