Bark zinc content per bark dry mass

Formal name:  bark zinc content per bark dry mass
Local identifier:  TOP391
Synonym Term:  bark Zn content per dry mass
Related Term:  bark Zn concentration

Definition:  The ratio of the quantity (SEP:quantity) of zinc (CHEBI:zinc atom) in the bark (PO:bark) to the corresponding bark (PO:bark) mass (PATO:mass) assessed after drying
Formal Unit:  mass unit / mass unit or amount unit / mass unit

Comment:  The quantity of zinc 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.
