Effects of priming on mean germination time (MGT) and time to achieve 50% germination (G50) of six genotypic groups.

	MGT (h)				G50 (h)
	Control	Priming	Ratio	t-Test	Control	Priming	Ratio	t-Test
Group 1	51.8	29.9	0.58	**	60.0	28.9	0.48	**
Group 2	33.9	24.5	0.72	**	30.6	21.6	0.71	**
Group 3	38.5	27.8	0.72	**	37.8	25.0	0.66	**
Group 4	37.2	25.5	0.68	***	34.7	22.5	0.65	***
Group 5	37.0	15.6	0.42	*	34.3	12.0	0.35	ns
Group 6	31.0	20.5	0.66	**	28.8	17.3	0.60	**

Genotypic groups were determined by cluster analysis (illustrated in Figure 1), and the data are the means of genotypes. *, **, and *** indicate a significant difference (p < 0.05, p < 0.01, and p < 0.001, respectively), and “ns” indicates a non-significant difference between control and priming by a t-test.
