Stem wood boron content per stem wood dry mass

Formal name:  stem wood boron content per stem wood dry mass
Local identifier:  TOP603
Synonym Term:  stem wood B content per dry mass
Related Term:  stem wood B content
Related Term:  stem wood B concentration
Definition:  The ratio of the quantity (SEP:quantity) of boron (CHEBI:boron atom) in the stem wood (PO:stem, PO:secondary xylem) to the corresponding stem wood (PO:stem, PO:secondary xylem) mass (PATO:mass) assessed after drying
Formal Unit:  mass unit / mass unit or amount unit / mass unit

Comment:  The quantity of boron 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.
