Leaf aluminium content per leaf area

Formal name:  leaf aluminium content per leaf area
Local identifier:  TOP468
Synonym Term:  leaf Al content per area
Related Term:  leaf Al content
Related Term:  leaf Al concentration
Definition:  The ratio of the quantity (SEP:quantity) of aluminium (CHEBI:aluminium atom) in the leaf (PO:leaf) or component thereof, i.e. leaf lamina or leaflet (PO:leaf lamina, PO:leaflet) per respective area (TOP:leaf area, TOP:leaf lamina area, TOP:leaflet area)
Formal Unit:  mass unit / area unit or amount unit / area unit

Comment:  The quantity of aluminium 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.
