Stem manganese content per stem dry mass

Formal name:  stem manganese content per stem dry mass
Local identifier:  TOP497
Synonym Term:  stem Mn content per dry mass
Related Term:  stem Mn content
Related Term:  stem Mn concentration
Definition:  The ratio of the quantity (SEP:quantity) of manganese (CHEBI:manganese atom) in the stem (PO:stem) to the corresponding stem (PO:stem) mass (PATO:mass) assessed after drying
Formal Unit:  mass unit / mass unit or amount unit / mass unit

Comment:  The quantity of manganese 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.
