Other claims from this paper (10)
- Intervention effect The long photoperiod shortened spike growth compared with the short photoperiod.
- Intervention effect The long photoperiod stimulated early flowering by shortening Stage III.
- Intervention effect The long photoperiod reduced assimilate accumulation in the spike.
- Intervention effect The long photoperiod resulted in fertile floret loss.
- Intervention effect Long photoperiod supplemented with red light shortened the time required to complete Stages I-II.
- Intervention effect Long photoperiod supplemented with red light raised assimilate supply in the spike.
- Intervention effect Long photoperiod supplemented with red light promoted anther development before polarization initiation.
- Intervention effect Long photoperiod supplemented with red light increased fertile FP number during Stage III.
- Observation Fertile FP development was maintained during Stage IV until the floret primordia became fertile florets.
- Recommendation The authors propose a light regimen that gives a shorter spike growth phase and a higher fertile floret number in wheat.
