Other claims from this paper (15)
- Intervention effect Grain yield differed significantly between low and high night temperature in all experiments.
- Intervention effect High night temperature decreased grain yield by 16.7% in the first season.
- Intervention effect High night temperature decreased grain yield by 9.1% in the second season.
- Intervention effect High night temperature decreased grain yield by 9.6% in the third season.
- Intervention effect High night temperature decreased grain yield by 8.0% in the fourth season.
- Mechanism Lower biomass and harvest index partly accounted for yield loss under high night temperature.
- Mechanism Low night temperature produced higher total dry weight through higher crop growth rate.
- Intervention effect Night warming during reproduction reduced yield.
- Mechanism Yield loss under night warming was attributed to lower grain weight and harvest index.
- Mechanism Yield loss in 2009WS was attributed to decreased grain filling.
- Intervention effect An approximately 4-degree high versus low night temperature difference reduced mean yield 11% across four seasons.
- Observation N22 was tolerant to high night temperature.
- Observation PSBRc52 was tolerant to high night temperature.
- Observation Swarna was tolerant to high night temperature.
- Observation IR8 was tolerant to high night temperature.
