Other claims from this paper (14)
- Intervention effect Inhibition of photosynthesis decreased starch content faster than sugars.
- Intervention effect High nitrogen fertilizer was associated with a sudden carbohydrate decrease about five days before heading.
- Intervention effect Inhibiting photosynthesis 16–7 days before heading decreased accumulated carbohydrates.
- Intervention effect Early ripening led to lighter thousand-kernel weight.
- Observation Early ripening decreased spikelets per ear.
- Observation Carbohydrate reaccumulation in culms was maximal among plots with reduced accumulation power.
- Intervention effect Shading at 6–15 days after heading caused increased transport of accumulated carbohydrates to the ear.
- Observation Shading at 6–15 days after heading increased incompletely developed grains.
- Intervention effect Photosynthesis inhibition at 16–25 days after heading delayed grain development.
- Observation Photosynthesis inhibition at 16–25 days after heading increased poorly developed grains.
- Observation Photosynthesis inhibition at 16–25 days after heading lowered thousand-kernel weight.
- Intervention effect Shading 26–35 days after heading did not influence kernel development.
- Association Culm carbohydrate accumulation was positively related to photosynthetic power and accumulation to the ear.
- Observation Authors estimated carbohydrate accumulation suitable for seed production at about 28–29%.
