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