Figure 1. Seed after-ripening releases dormancy and promotes germination. Time course of cress (Lepidium sativum) endosperm rupture at 18 °C in continuous light. Seeds just after harvest (fresh seeds, open circles) and after 6 months of air-dry storage (after-ripened (ar), filled circles) at room temperature. The black line indicates 50 % endosperm rupture of the seed populations, the dotted line connects it to corresponding times t50% (fresh, 32 h), the dashed line to t50% (after-ripened, 17 h), i.e. the after-ripened / fresh t50% ratio is 0.53. Means of three times 50 seeds +/- SE are given.
