Other claims from this paper (9)
- Intervention effect Increasing planting density significantly increased grain yield of DH605 maize.
- Intervention effect Grain yields of XD20 and DH618 maize rose at first with planting density and then stabilized.
- Intervention effect High planting density significantly elevated plant height parameters and center of gravity of summer maize compared with low density.
- Intervention effect High planting density markedly reduced light transmittance within the bottom and ear layers of maize.
- Intervention effect High planting density increased the risk of lodging, particularly for the XD20 hybrid.
- Mechanism DH605 improved mechanical strength of maize by enhancing light distribution in the ear and bottom layers and optimizing basal internode characteristics.
- Intervention effect Grain yield under the DH605 high-density treatment was 10.68 to 34.11% higher than under XD20 at high density.
- Intervention effect Lodging rates under the DH605 high-density treatment were reduced by 72.66 to 92.29% relative to XD20 at high density.
- Association Cellulose content and vascular bundle area in basal internodes explained 61.70% of mechanical strength variance in maize.
