Other claims from this paper (13)
- Intervention effect Fructan hydrolase activity in wheat increased significantly as planting density rose from D1 to D4.
- Intervention effect The highest fructan hydrolase activity under D4 was 457.47 μg/h/g higher than under D1.
- Intervention effect Increasing density increased the contribution rate of dry matter accumulation to grain after anthesis (CDMA), with a highest increase of 33.67%.
- Intervention effect The density-driven increase in CDMA significantly reduced stem strength.
- Association CDMA and stem strength showed a significant negative association.
- Intervention effect CDMA was significantly lower under D3 than under D4.
- Intervention effect Stem strength remained higher after anthesis under D3 than D4, as an adaptive response to mitigate lodging risk.
- Mechanism Stem storage compounds can promote grain filling and weight increase in inferior grains.
- Intervention effect The number of grains per spike and 1000-grain weight decreased significantly with increasing planting density.
- Intervention effect Over two years, spikes in D3 increased by a maximum of 211.67 × 104 ha−1 compared with D1.
- Intervention effect Over two years, spikes in D3 increased by a maximum of 99.17 × 104 ha−1 compared with D2.
- Intervention effect The number of grains per spike was significantly higher than under D4, the highest difference being 3.68 grains.
- Recommendation In the North China Plain, a sowing density of 270 × 104 plants/ha is recommended for wheat to maintain stem strength and obtain high yields.
