The effect of two priming techniques: hardening (prehydration treatment) and solid matrix priming (SMP) was studied on the seeds of two parsley varieties (Cukrowa and Berlińska) in 3-year laboratory experiments. On the images obtained from scanning electron microscope (SEM) there is a parsley embryo developing during germination up to the moment of radicle emergence. On the surface of primed seeds, in particular using the hardening method, lateral cracks are visible. The respiratory activity of primed seeds was similar to that of non-primed in the period of initial 24 h of germination, but significantly higher after 48 h. As compared to non primed seeds solid matrix priming significantly increased the percentage and the speed of germination. Nevertheless, pelleting reduced the positive effect of priming on the germination ability, without affecting the germination speed. After 18 months of storage, the vigour of primed seeds, particularly through hardening, had significantly decreased.
