e0“Mild increase in night temperature during the reproductive growth stage reduced yield which was attributed to decrease in grain weight, harvest index, grain filling (2009WS), and spikelets number per panicle (2010DS and 2011DS).”

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.
- 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.
- Mechanism Yield loss in 2010DS and 2011DS was attributed to fewer spikelets per panicle.
- 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.
