Title

Other claims from this paper (5)
- Intervention effect Within 2 days of flooding, oxygen in the soil water decreased to below 2%.
- Intervention effect Flooding inhibited net uptake of nitrogen to barley shoots.
- Intervention effect Flooding decreased the average nitrogen concentration in barley shoots.
- Observation Onset of chlorosis of the older leaves followed the changes in nitrogen status in barley.
- Mechanism Inhibited nitrogen uptake and nitrogen redistribution within the shoot are suggested to contribute to early leaf senescence and retarded shoot growth in flooded barley.
