Title

Effects of high night temperature on yield and agronomic traits of irrigated rice under field chamber system condition

Yunbo Zhang; Qiyuan Tang; Peng Shaobing; et al. Australian Journal of Crop Science 2013

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 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.

Masami HIMEDA; Seiichi IZUMI Japanese Journal of Crop Science 1965. doi:10.1626/jcs.33.399

Other claims from this paper (9)

Intervention effect More irregular disposition of rice plants caused a greater decrease in grain weight per unit area.
Mechanism Decrease of grain weight was caused by a decrease in the number of panicles per unit area.
Association In Fujiminori, the number of panicles decreased as irregularity in plant disposition increased.
Intervention effect In Fujiminori, grain weight per panicle remained unchanged as irregularity in plant disposition increased.
Association In Manryo, grain weight per panicle increased.
Association In Manryo, the number of panicles decreased.
Intervention effect In plots of cv 30∼100 %, no decrease of grain weight was observed relative to the plot of cv 0 %.
Intervention effect In Fujiminori, the decrease in grain weight with irregular disposition was more marked at low seeding density than at high seeding density.
Intervention effect In Manryo, the difference in the effect of irregular disposition on grain weight between spacing densities was not clear.
