Other claims from this paper (14)
- Observation Milyang 23 had higher total dry matter production under standard and heavy nitrogen application.
- Observation Milyang 23 had a higher harvest index under standard and heavy nitrogen application.
- Intervention effect Heavy nitrogen application increased sink capacity in all tested cultivars.
- Intervention effect Heavy nitrogen application increased leaf area in all tested cultivars.
- Observation Korean cultivars had 49,000 spikelets per unit leaf area versus 37,000 in Japanese cultivars.
- Mechanism The Korean versus Japanese difference in spikelets per leaf area was attributed to spikelets per ear.
- Association Korean cultivars had a lower increase in leaf area relative to nitrogen absorption from transplanting to heading.
- Association Korean cultivars had a higher increase in sink capacity relative to nitrogen absorption from transplanting to heading.
- Observation Korean cultivars had a much higher sink/source ratio than Japanese cultivars.
- Observation Old Japanese cultivars had a higher sink/source ratio than new types because of larger ears.
- Observation Korean cultivars were interpreted as producing ears with higher sink capacity without excessive leaf growth.
- Association Harvest index remained high as total dry weight rose after heavy nitrogen application.
- Observation Korean cultivars combined a higher sink/source ratio than old Japanese types with the short culm of new types.
- Recommendation The authors recommend developing cultivars with Korean cultivar advantages while minimizing taste, disease-tolerance and cold-tolerance shortcomings.
