Other claims from this paper (14)
- Intervention effect Low nitrogen increased NSC translocation during grain filling.
- Intervention effect Low nitrogen significantly shortened the active grain-filling period.
- Intervention effect Low nitrogen increased grain-filling rate in superior spikelets.
- Observation SY63 had higher grain weight than LYPJ.
- Observation SY63 had higher grain-filling percentage than LYPJ.
- Observation SY63 had higher stem NSC before heading than LYPJ.
- Observation SY63 had greater NSC translocation after heading than LYPJ.
- Intervention effect Low nitrogen increased AGP, StS and SBE activity between panicle initiation and heading.
- Association Starch-synthesis enzyme activities positively correlated with stem NSC increases.
- Intervention effect Low nitrogen increased α-amylase, β-amylase and SPS activities during grain filling.
- Association Starch-to-sucrose enzyme activities positively correlated with stem NSC remobilization.
- Observation Investigated enzyme activities were higher in SY63 than LYPJ.
- Mechanism The authors suggest low nitrogen increases enzyme activities, causing greater starch and NSC accumulation and remobilization in SY63.
- Recommendation The authors recommend reducing nitrogen and choosing an appropriate cultivar to improve rice grain yield and sustainability.
