Other claims from this paper (19)
- Intervention effect Warming increased total N accumulation of rice by 8.27–40.53% relative to the control across the jointing, anthesis and maturity stages.
- Intervention effect No significant difference in total N accumulation was detected among the three warming treatments.
- Intervention effect Warming substantially decreased N translocation efficiency in rice.
- Intervention effect Warming led to more N retained in rice plant stems during grain filling.
- Intervention effect Warming decreased the N harvest index, N utilization efficiency based on grain yield and N utilization efficiencies based on biomass in both growing seasons.
- Intervention effect Warming significantly increased aboveground biomass of rice by 9.26–16.18% at the jointing stage.
- Intervention effect Warming decreased aboveground biomass of rice by 2.75–9.63% at the maturity stage.
- Intervention effect Warmed plots tended to have fewer effective panicles and grains per spike in rice.
- Intervention effect Warming produced irregular changes in 1000-grain weight of rice.
- Intervention effect Daytime warming (DW) increased carbon gain by photosynthesis in rice.
- Intervention effect Nighttime warming (NW) increased carbon loss by night respiration in rice.
- Intervention effect The daytime higher-temperature treatment reduced photosynthetic rate and photosynthetic product in rice.
- Intervention effect AW raised the daily mean canopy temperature of rice by 2.0 ºC relative to CK.
- Intervention effect DW raised the daily mean canopy temperature of rice by 1.1 ºC relative to CK.
- Intervention effect NW raised the daily mean canopy temperature of rice by 1.3 ºC relative to CK.
- Intervention effect AW reduced rice grain yield by 10.07% on average across both years.
- Intervention effect DW reduced rice grain yield by 5.05% on average across both years.
- Intervention effect NW reduced rice grain yield by 7.89% on average across both years.
- Intervention effect Under anticipated climate warming, rice productivity would further decline in the Yangtze River Basin.
