Shoot photosynthetic rate per shoot dry mass

Formal name:  shoot photosynthetic rate per shoot dry mass
Local identifier:  TOP358
Synonym Term:  shoot photosynthesis per shoot dry mass
Definition:  the amount of carbon (CHEBI:carbon atom) assimilated via photosynthesis by the shoot (PO:shoot system) including leaves (PO:leaf) and stem (PO:stem) per unit mass (PATO:mass) of the respective shoot system assessed after drying and unit time
Formal Unit:  amount unit / mass unit / time unit

Comment:  Photosynthesis is in general related to leaves (TOP:leaf photosynthetic rate per leaf dry mass) or active stem tissue (TOP:stem photosynthetic rate per stem dry mass) but can also be related to the shoot system. The following environmental conditions during photosynthesis measurements need to be specified: irradiance, temperature, CO2 and O2 concentration of the air, altitude or air pressure.
