Formal name:  cotyledon zinc content per cotyledon dry mass
Local identifier:  TOP448
Synonym Term:  cotyledon Zn content per dry mass
Related Term:  cotyledon Zn concentration
Related Term:  cotyledon Zn content
Definition:  The ratio of the quantity (SEP:quantity) of zinc (CHEBI:zinc atom) in the cotyledon (PO:cotyledon) to the corresponding cotyledon (PO:cotyledon) 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.
