Table 2.

The seed-setting rate and 1000-grain weight of pse(t) in the 24 °C and 28 °C treatments

	24 °C treatment		28 °C treatment
	Mutant	Control	Mutant	Control
Seed-setting rate (%)	72.3±5.3 b	93.2±3.1 c	56.2±5.0 a	95.1±2.1 c
1 000-grain weight (g)	23.1±0.3 b	23.6±0.4 bc	20.1±0.4 a	24.4±0.4 c
DTS (d)	16	35	14	31

Values are the mean±SE of four replicates. In each row, means marked with the same letter are not significantly (P<0.05) different by the Duncan Test. DTS: Days from 28 °C treatment to the beginning of the 4th leaf senescence
