Shoot calcium content per shoot dry mass

Formal name:  shoot calcium content per shoot dry mass
Local identifier:  TOP680
Synonym Term:  shoot Ca content per dry mass
Related Term:  shoot Ca concentration
Related Term:  shoot Ca content
Definition:  The ratio of the quantity (SEP:quantity) of calcium (CHEBI:calcium atom) in the shoot (PO:shoot system) to the corresponding shoot (PO:shoot system) mass (PATO:mass) assessed after drying
Formal Unit:  mass unit / mass unit or amount unit / mass unit

Comment:  The quantity of calcium 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.
