Other claims from this paper (11)
- Intervention effect Nitrogen application induced an increasing trend in nitrogen accumulation in flowering rapeseed plants.
- Intervention effect Nitrogen application induced an increasing trend in the number of siliques per plant, branches per plant and seeds per silique.
- Observation There were significant correlational relationships between nitrogen accumulation, silique number, branch number, seed number and seed yield, except for seed number.
- Association Nitrogen application, nitrogen accumulation and silique number had higher effects on seed yield than the other indexes.
- Mechanism The effect of nitrogen application on seed yield was mainly achieved through its influence on silique, branch and seed numbers.
- Intervention effect Raising nitrogen from 180 to 240 kg ha-1 decreased nitrogen utilization efficiency and partial productivity of nitrogen fertilizer.
- Intervention effect NR gene expression in leaves was significantly increased under N180 and N240 relative to N0.
- Intervention effect NR and GS enzyme activities in leaves were significantly increased under N180 and N240 relative to N0.
- Observation NR gene expression and NR and GS activity in leaves reached peak values at 180 kg ha-1 of nitrogen application.
- Intervention effect Nitrogen application hardly influenced rapeseed seed quality.
- Intervention effect Nitrogen application hardly influenced gene expression and activity of ACCase, FAD2 and FAD3 in young seed.
