- Intervention effect Flooded old and new roots declined in specific gravity from 0.78 to 0.58 between days 5 and 25.
- Observation Specific gravity of old drained roots did not change.
- Observation After five days, new roots had less aerenchyma than older roots.
- Observation After 25 days, new root specific gravity equaled old root specific gravity.
- Intervention effect Flooding increased mortality of preexisting roots.
- Intervention effect Flooding inhibited growth of new roots.
