Seed potassium content per seed dry mass

Formal name:  seed potassium content per seed dry mass
Local identifier:  TOP579
Synonym Term:  seed K content per dry mass
Related Term:  seed K concentration
Related Term:  seed K content
Definition:  The ratio of the quantity (SEP:quantity) of potassium (CHEBI:potassium atom) in the seed (PO:seed) to the corresponding seed (PO:seed) mass (PATO:mass) assessed after drying
Formal Unit:  mass unit / mass unit or amount unit / mass unit

Comment:  The quantity of potassium 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.
