  1. Abbreviation of treatments: NA: natural ageing at room temperature (~ 25 °C). HP, Spd, H1: different solutions, distill water, 1 mM spermidine, 1 mM hydrogen peroxide for germination/priming. 1d, 2d, etc.: duration of artificial ageing. Deh.: seeds were desiccated after recognizable dehiscence instead of the 24th hour of germination. E.g.: NPB14-Spd-6d-HP, Nipponbare harvested in 2014 experiencing 1 mM-Spd priming, 6d-artificial-ageing, hydropriming subsequently. D: dehiscence percentage at the 48th hour of germination. GP: germination percentage; SE: standard error; *GP of NPB16-Deh.H1-3d was significantly higher than NPB16-Deh.HP-3d (P < 0.05); **GP of NPB14-Deh.HP was extremely significantly higher than NPB16-Deh.HP (P < 0.01). Pre-dehiscence germination of NPB14-Deh.HP, NPB16-Deh.HP and NPB16-Deh.H1 were based on counting leftover non-germinative seeds after DehM
