GP = germination percent; MGT = mean germination time; IGT = initial germination time; HL = hypocotyl length; RL = radicle length; LRH = the length of radicle and hypocotyl; RRH = the ratio of radicle length to hypocotyl length. d.f.: degrees of freedom; ns: not significant; *P < 0.05; **P < 0.01; ***P < 0.001.
