Leaf copper content per leaf dry mass

Formal name:  leaf copper content per leaf dry mass
Local identifier:  TOP455
Synonym Term:  leaf Cu content per dry mass
Related Term:  leaf Cu concentration
Related Term:  leaf Cu content
Definition:  The ratio of the quantity (SEP:quantity) of copper (CHEBI:copper atom) in the leaf (PO:leaf) or component thereof, i.e. leaf lamina or leaflet (PO:leaf lamina, PO:leaflet) per respective unit dry mass (TOP:leaf dry mass, TOP:leaf lamina dry mass, TOP:leaflet dry mass)
Formal Unit:  mass unit / mass unit or amount unit / mass unit

Comment:  The quantity of copper 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.
