Other claims from this paper (5)
- Observation Temperature phasing alone showed little advantage for average seed yield rate over experimental values.
- Observation Combined temperature and photoperiod phasing could improve seed yield by approximately 15% over USU values for Hoyt.
- Observation Longer later photoperiods were predicted to increase mass per seed.
- Observation Extended photoperiod timing and duration could reduce seed number per square metre.
- Mechanism Reduced seed sink strength at elevated CO2 may feed back to inhibit photosynthesis.
