Other claims from this paper (11)
- Intervention effect Silicon supply enhanced total plant Si content in wheat across both CO2 regimes, compared with a Si-free control.
- Intervention effect Silicon supply did not affect the maximum quantum efficiency of photosystem II (Fm/Fv) in wheat.
- Intervention effect Shoot C concentration in wheat slightly decreased with higher silicon supply, possibly due to dilution or changes in C allocation.
- Intervention effect The combination of Si addition and elevated CO2 significantly increased phytolith formation and PhytOC accumulation in wheat.
- Intervention effect No detectable phytoliths were found in wheat grown without Si supply.
- Intervention effect The C concentration in phytoliths was lower at 1.5 mM Si than at 0.5 mM Si under both aCO2 and eCO2.
- Intervention effect The C/N ratio in phytoliths decreased with increasing silicon supply.
- Intervention effect The C/N ratio in phytoliths was lower under eCO2 than under aCO2.
- Intervention effect The highest PhytOC content in wheat (1.15 mg plant-1) was observed at eCO2 with 1.5 mM Si.
- Intervention effect PhytOC content at eCO2 with 1.5 mM Si was approximately 50% higher than in the same Si treatment at aCO2.
- Recommendation Silicon fertilisation has potential in climate-resilient wheat cultivation.
