Other claims from this paper (12)
- Intervention effect Optimized nitrogen fertilizer application increased the number of branches and spikelets in rice.
- Intervention effect Optimized nitrogen fertilizer application improved panicle length, panicle-neck internode diameter and vascular bundle number in rice.
- Intervention effect Under optimized nitrogen application, high effective leaf areas of the flag and second upper leaves increased in rice.
- Intervention effect Under optimized nitrogen application, the net photosynthetic rate of the upper three rice leaves was promoted.
- Intervention effect Under optimized nitrogen application, photosynthetic productivity went up by a large margin in rice.
- Intervention effect Under optimized nitrogen application, soluble protein and chlorophyll content of rice leaves increased.
- Intervention effect Under optimized nitrogen application, soluble sugar and malondialdehyde (MDA) content of rice leaves decreased.
- Mechanism Decreased malondialdehyde (MDA) is interpreted by the authors as slowing leaf senescence in rice.
- Intervention effect Under optimized nitrogen application, photosynthetic time increased in rice.
- Mechanism The authors interpret MOC1, LAX1, SP1 and GS1;1 expression as conducing to more secondary branches and spikelets in rice.
- Intervention effect Optimized nitrogen application got rice a higher yield.
- Mechanism Changes in organ formation and panicle structure, with physiological and molecular responses, are proposed to underlie big panicle development in rice.
