Other claims from this paper (9)
- Intervention effect Plant dry weight decreased progressively across the 2, 4, 6 and 8 cm sets.
- Observation Net assimilation rate was lowest in the 8 cm set.
- Observation The dry weight of nonphotosynthetic organs per leaf area did not differ among sets.
- Intervention effect Lower water levels induced heavy leaf water deficit.
- Observation No water deficit was observed in stems or roots.
- Association Leaf water deficit related to submerged-root area per leaf area.
- Association Leaf respiratory activity showed no change with water deficit.
- Observation Leaf nitrogen content showed no special depression.
- Mechanism Calculated and observed growth agreed, supporting suppressed leaf photosynthesis as the primary cause of growth depression.
