Other claims from this paper (7)
- Intervention effect Continuous 18 h photoperiod yielded fewer leaves than continuous 12 h.
- Intervention effect Leaves appeared faster under continuous 18 h than 12 h photoperiod.
- Intervention effect Transfer from 12 h to 18 h at terminal spikelet appearance advanced anthesis by 4 d relative to continued 12 h.
- Observation Continuous 18 h photoperiod completed the phase to anthesis most rapidly.
- Observation Photoperiod sensitivity peaked around 15 days after emergence then declined.
- Intervention effect Spikelet number declined with delayed transfer to long days and reached a minimum with transfer 16–20 d after emergence.
- Intervention effect Exposure to long days between 10 and 35 d after emergence tended to increase leaf appearance rate.
