Other claims from this paper (14)
- Intervention effect Rice biomass did not change significantly among nitrogen rates over ten days.
- Association Leaf and root nitrogen contents increased with nitrogen level.
- Association Leaf and root 15N abundance decreased as nitrogen level increased.
- Observation Leaf 15N abundance was higher than root abundance.
- Intervention effect Plant nitrogen absorption increased under high nitrogen treatment.
- Mechanism The authors infer nitrogen transfer from roots to leaves from dilution of previously absorbed 15N.
- Intervention effect N deficiency(N 0 mg/L) increased nitrogen loss from rice.
- Intervention effect over N supply(N 160 mg/L) increased nitrogen loss from rice.
- Intervention effect N supply at 80 mg/L increased nitrogen utilization.
- Association Rice growth stage affected nitrogen loss rate.
- Association At 80 mg/L nitrogen, loss from rice increased from 11.6% to 22.3% as growth period advanced.
- Association NH+4-N contents and GOT activities increased with nitrogen amount.
- Association Rice leaf pH increased with nitrogen amount.
- Mechanism The authors attribute lower nitrogen use efficiency to nitrogen loss from rice tissue.
