Other claims from this paper (11)
- Intervention effect Ear tip removal reduced kernels per ear by 20 to 40%.
- Intervention effect Early defoliation reduced kernel growth rate and filling duration, lowering kernel weight.
- Intervention effect Defoliation decreased soluble carbohydrate content in the internode above the ear.
- Intervention effect The carbohydrate decline was faster after later defoliation.
- Intervention effect Defoliated stem internodes had higher N concentration than controls.
- Intervention effect Stem internode N concentration did not decline after defoliation.
- Intervention effect Reduced ear size increased internode soluble carbohydrate and N concentrations.
- Intervention effect Reducing ear size increased grain nitrogen concentration.
- Intervention effect Reduced ear size did not affect kernel growth rate, final weight or carbohydrate concentration at maturity.
- Mechanism Stem remobilization responses differ between N and soluble carbohydrates.
- Mechanism Kernel growth and seed size may approach their potential limits, with other factors restraining further growth.
