Other claims from this paper (16)
- Intervention effect Increasing density first increased and then decreased pod numbers per unit area.
- Observation The optimal density was 58.5 × 10 4 plants ha −1 for both varieties.
- Intervention effect High plant density produced a decrease in green leaf area index relative to low density.
- Intervention effect High plant density produced a decrease in chlorophyll content relative to low density.
- Intervention effect High plant density produced a increase in malondialdehyde content relative to low density.
- Intervention effect High density had higher pod area index (PAI) after peak anthesis.
- Intervention effect High density had higher pod photosynthesis after peak anthesis.
- Intervention effect High density had higher radiation use efficiency (RUE) after peak anthesis.
- Observation High density was associated with higher dry matter accumulation.
- Observation High density was associated with higher nitrogen utilization efficiency.
- Observation High density was associated with higher yield.
- Intervention effect High density decreased root length.
- Intervention effect High density decreased root tips.
- Intervention effect High density decreased root surface area.
- Intervention effect High density decreased root volume.
- Recommendation The authors recommend increasing density within a certain range for high seed yield.
