Leaf mass per area trait

Formal name:  leaf dry mass per leaf area trait
Abbreviation:  LMA
Local identifier:  TOP52
Related Term:  specific leaf weight
Definition:  the ratio of the dry mass of a leaf (TOP:leaf dry mass) or component thereof, i.e. leaf lamina (TOP:leaf lamina dry mass), to the corresponding area (TOP:leaf area, TOP:leaf lamina area)
Formal Unit:  mass unit / area unit

Comment:  "when known, the component of the leaf on which the measurements have been taken should be specified: leaf (PO:leaf), leaf lamina (PO:leaf lamina). The term ""specific leaf weight"" should not be used since the mass of an object is constant, while its weight varies with the effect of gravity."
