The Chamber for Studying Rice Response to Elevated Nighttime Temperature in Field

Table 2

Effects of the field chamber system on rice grain filling rate and yield of IR72 and IR8 in 2009 DS. Data are mean ± SE of four replicates.

Variety	Temperature	Grain filling (%)	Grain yield; (g per m^2)
IR72	T22	74.0±3.22a	443.4±61.07a
	T27	68.8±5.11a	422.1±81.12a
	Ambient	81.7±5.11a	493.3±55.94a
IR8	T22	68.1±6.42a	318.1±70.73a
	T27	37.8±2.69b	106.9±24.61b
	Ambient	77.9±3.36a	426.5±62.55a

Mean in column with different small letter was not significantly different between treatments.
