Other claims from this paper (15)
- Intervention effect Boll number per plant and individual boll weight both decreased with increasing plant density in cotton.
- Intervention effect Cotton yield was highest under 12 plants m −2.
- Mechanism Yield was driven by optimized biomass accumulation and partitioning in cotton.
- Observation Sink/source ratio of cotton can be adjusted by plant density.
- Observation Biomass partitioning in reproductive organs was highest under 12 plants m −2.
- Observation Square per leaf area, boll load per leaf area and 13 C proportion of reproductive organ were observed under 12 plants m −2.
- Intervention effect Higher LAI was observed under high plant density at peak boll setting and boll opening in cotton.
- Observation LAI was correlated with seed cotton yield with a significant parabolic relationship.
- Intervention effect Photosynthesis ability of the fourth leaf and chlorophyll content decreased with increasing plant density in cotton.
- Intervention effect Canopy apparent photosynthesis rate was maximal under 12 plants m −2.
- Mechanism High population photosynthetic capacity in cotton was probably the result of high plant density, net photosynthesis ability and chlorophyll content.
- Observation Optimum LAI of 4.47–4.8 was observed under 12 plants m −2.
- Observation LAI and SPAD were negatively related to the sink/source ratio of cotton, according to path analysis.
- Observation CAP was positively related to the sink/source ratio of cotton, according to path analysis.
- Observation High-yield cotton populations displayed a superior photosynthetic capacity.
