Claim · model-written summary
Reducing N by 28% produced no significant difference in sink and source characteristics of Tianyou 998.
Verbatim
e0“on rice sink and source characteristics were studied using four varieties(Yuejingsimiao 2,Guixiangzhan,Huayou 8305 and Tianyou 998) in field experiment”
e1“Compared by conventional N,reduction of N by 28% would maintain or promote the rice source and sink coordination,which resulted in no significant decrease in yield”
e4“Reduction of N by 28% improved sink capacity and ratio of spikelets No.and leaf area in Yuejingsimiao 2 and Guixiangzhan,improved available filled ratio of sink in Huayou 8305,while there was no significant difference in Tianyou 998”

- Intervention effect Reducing N by 28% relative to conventional N caused no significant decrease in rice yield.
- Intervention effect Reducing N by 28% would maintain or promote rice source and sink coordination relative to conventional N.
- Intervention effect Reducing N by 28% increased grain yield of Yuejingsimiao 2 by 11.99% relative to conventional N.
- Intervention effect Reducing N by 28% increased grain yield of Guixiangzhan by 5.51% relative to conventional N.
- Intervention effect Reducing N by 28% increased grain yield of Huayou 8305 by 6.46% relative to conventional N.
- Mechanism The yield increase under 28% N reduction is attributed to enhanced photosynthesis or sheath and stem transfer ability in rice.
