Other claims from this paper (9)
- Intervention effect Pod removal decreased bean gas-exchange photosynthesis, stomatal conductance and intercellular CO2 pressure.
- Association The photosynthetic decrease was associated with increased starch content.
- Intervention effect Pod removal did not change Rubisco and other photosynthetic component amounts.
- Intervention effect Under saturating CO2, pod removal did not decrease photosynthesis measured by O2 evolution.
- Intervention effect Depodded plants showed reduced CO2-limited photosynthesis for a given Rubisco content.
- Intervention effect Rubisco specific activity and activation state did not decrease in depodded plants.
- Intervention effect Shading restored the gas-exchange photosynthetic rate in depodded plants.
- Intervention effect Shading restored CO2-limited photosynthesis per Rubisco protein to the level of plants with pods.
- Intervention effect Shading decreased starch accumulation.
