Other claims from this paper (10)
- Intervention effect Nitrogen stress accelerated the decline in leaf CO2 exchange.
- Observation Leaf reduced nitrogen content declined during nitrogen remobilization to pods.
- Intervention effect Pod growth declined under developing nitrogen stress.
- Association Photosynthetic carbon assimilation exceeded reproductive demand during nitrogen stress.
- Observation Nonstructural carbohydrates accumulated in tissues during nitrogen stress.
- Intervention effect After nitrate resupply, specific root nitrate uptake exceeded that of nonstressed plants.
- Observation After nitrate resupply, reduced nitrogen content in leaves increased little.
- Observation Net nitrogen remobilization from leaves ceased after nitrate resupply.
- Association Photosynthesis stabilized at about 51% of the nonstressed rate.
- Observation Available photosynthesis and accumulated carbohydrate pools supported increased nitrate uptake and pod growth during recovery.
