Dispersule mass trait

Formal name:  dispersule mass
Local identifier:  TOP102
Synonym Term:  propagule mass
Synonym Term:  diaspore mass
Related Term:  diaspore weight
Definition:  the mass (PATO:mass), either fresh or dried, of a dispersule (Perez:dispersule) or component thereof, i.e. seed, fruit or germinule (PO:seed, PO:fruit, Leda:germinule)
Formal Unit:  mass unit

Comment:  "when known, the component of the dispersule on which the measurements have been taken should be specified: seed, fruit, germinule. When known the state of the entity which has been measured should be specified: fresh (sampled without loosing water) or dry. The term ""diaspore weight"" should not be used since the mass of an object is constant, while its weight varies with the effect of gravity. "
