Wood iron content per wood dry mass trait

Formal name:  wood iron content per wood dry mass
Local identifier:  TOP736
Synonym Term:  wood Fe content per dry mass
Related Term:  wood Fe content
Related Term:  wood Fe concentration
Definition:  The ratio of the quantity (SEP:quantity) of iron (CHEBI:iron 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 iron 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.
