- Intervention effect Removing silicon during reproduction decreased straw dry weight by 20%.
- Intervention effect Removing silicon during reproduction decreased grain dry weight by 50%.
- Intervention effect Adding silicon during reproduction increased straw dry weight by 243%.
- Intervention effect Adding silicon during reproduction increased grain dry weight by 30%.
- Intervention effect Adding or removing silicon during vegetative or ripening stages had little effect on straw and grain dry weight.
- Intervention effect Adding silicon in reproduction markedly increased filled spikelets.
- Intervention effect Silicon addition or removal had little influence on thousand grain weight at any stage.
- Observation About 66% of whole-plant silicon was absorbed during reproduction.
- Observation About 70 to 75% of leaf-blade silicon was absorbed during reproduction.
- Observation About 75% of panicle silicon was absorbed during ripening, with no detected growth benefit.
- Observation Forty to 50% of silicon absorbed in vegetative and reproductive stages was present in leaf blades.
- Observation Twenty to 30% of silicon absorbed during ripening was present in leaf blades.
- Recommendation The authors concluded that silicon supply during reproduction is most important for rice growth.
