Other claims from this paper (12)
- Observation Specific dark respiration was highest at rooting and declined through heading and afterward.
- Observation Plant nitrogen concentration decreased during ontogeny.
- Association Nitrogen concentration varied with nitrogen supply at each growth stage.
- Association Specific respiration did not vary with nitrogen supply at each growth stage.
- Association Nitrogen concentration and respiration showed a linear relationship across growth stages.
- Association The nitrogen concentration–respiration regression slope varied greatly by growth stage.
- Observation Early growth efficiency was 60–70% regardless of nitrogen supply.
- Intervention effect More nitrogen lowered growth efficiency during grain filling.
- Intervention effect Nitrogen fertilization increased phytomass.
- Intervention effect Nitrogen fertilization increased respiratory loss.
- Observation Respiration consumed more carbohydrates in 1997 than in 1996.
- Observation Late-stage growth efficiency was lower in 1997 than in 1996.
