Other claims from this paper (14)
- Intervention effect Heat at flower spike emergence reduced photosynthetic CO2 assimilation in all varieties.
- Observation Mandelup, Iris and Jenabillup maintained the highest assimilation at flower spike emergence.
- Intervention effect Heat caused a greater reduction in assimilation at grain filling.
- Intervention effect Temperature treatments significantly affected PSII maximum quantum efficiency, especially at grain filling.
- Association Photosynthetic parameters correlated strongly with yield traits.
- Association Photosynthetic parameters correlated strongly with grain nutritional composition.
- Association These relationships depended strongly on heat stress timing.
- Observation Tolerant varieties had higher assimilation, ETR and Fv/Fm under heat.
- Observation Under HS38, reductions ranked A n above ETR above P r.
- Intervention effect Heat reduced grain carbohydrates in sensitive varieties.
- Intervention effect Heat increased grain protein in sensitive varieties.
- Observation Tolerant varieties remained stable under heat.
- Intervention effect Short-term heat at flowering did not affect yield.
- Mechanism The authors suggest internal carbon reserves buffer flowering-stage heat effects on yield.
