Other claims from this paper (12)
- Method / resource The apparatus measured nodule acetylene reduction and shoot gas exchange simultaneously.
- Observation Acetylene reduction was linear for at least five hours except initially.
- Method / resource Endogenous ethylene did not affect measurements.
- Method / resource Repeated acetylene reduction measurements had no apparent aftereffects.
- Intervention effect Acetylene reduction was undetectable in flooded soil and at severe desiccation.
- Intervention effect Acetylene reduction was undetectable at a soil water potential of -19.5 bars.
- Observation Acetylene reduction had a sharp optimum between flooded and severely dry soil.
- Mechanism Gas exchange restriction was proposed to explain flooding inhibition above -2 bars.
- Association Acetylene reduction decreased with further soil drying.
- Association The decrease in acetylene reduction correlated with decreases in photosynthesis and transpiration.
- Observation Dark respiration was inhibited less than the other measured processes.
- Mechanism Photosynthesis, transpiration, or direct nodule effects were proposed to account for nitrogen fixation inhibition below -2 bars.
