Leaf area after norflurazon treatment

	R29 (male)	S27 (female)	F1-S27 × R29	Relative to MPV	Relative to BPV
Relative ratio in leaf area compared with R29
A. Leaf area in 1st and 2nd leaves after three weeks sowing	1.00a	1.19 ± 0.15a	2.74 ± 0.33b	2.54	2.29
B. Leaf area in 3rd and 4th leaves after four weeks sowing	1.00a	1.92 ± 0.17b	1.50 ± 0.18ab	0.93	0.78

A. Seeds were sown on MS medium and grown for one week. The seedlings were transferred to MS medium with 1.0 μM norflurazon and grown for a further two weeks

B. Seeds were grown on MS medium with 1.0 μM norflurazon for one week, then transferred to MS medium for three weeks

Letters (a and b) indicate significant differences at p < 0.05 (Student’s t-test)
