¹⁾HKW, stored at 50℃ for 1 h after keep in water for 4 h at room temperature before germination; KW, keep in water for 4 h at room temperature before germination; CO, control, not pre-treated.
²⁾All values are mean±SD (n=3).
³⁾^a^-^fMeans with different superscripts within the same pre-treatment method are significantly different (p<0.05) by Duncan's multiple range test.
⁴⁾^A^-^CMeans with different superscripts within the same germination time are significantly different (p<0.05) by Duncan's multiple range test.
