Quantifying source-sink relationships of rice under high night-time temperature combined with two nitrogen levels

High night-time temperature (HNT) disturbs processes of both assimilate production (source) and assimilate accumulation (sink), and as a result substantially reduces yields of cereal crops. There have been reports that increasing nitrogen application can alleviate the negative impact of high-temperature stress on yield in rice (Oryza sativa L.). However, little is known about the interactive effect of HNT and nitrogen (N) supply on rice grain...
