Other claims from this paper (11)
- Intervention effect A 25% illumination reduction reduced yield by 75%.
- Intervention effect A 25% illumination reduction reduced formed tillers by 60%.
- Intervention effect A 25% illumination reduction reduced grain weight by 20%.
- Intervention effect An 80% illumination reduction caused total yield loss.
- Intervention effect Leaf area under reduced illumination was significantly lower.
- Intervention effect Photosynthesis did not differ significantly between control and 75% illumination.
- Intervention effect Lower light was associated with higher photochemical efficiency.
- Intervention effect Lower light was associated with reduced mesophyll resistance.
- Observation The genotype maintained small stature and showed no shade avoidance such as leaf elongation under low light.
- Intervention effect Nitrogen concentrations of 2.8 and 1.4 mmol/L led to no differences in plant growth.
- Recommendation The authors conclude that 1.4 mmol/L nitrogen is sufficient under the tested light intensities.
