Priming, a controlled-hydration treatment followed by redrying, improves the germination
and emergence of seeds from many species. We compared osmotic and matric priming to
determine which was the most effective treatment for improving broccoli seed germination
and to gain a greater understanding of how seed vigor is enhanced by priming. Broccoli
(Brassica oleraceaL. var. italica) seeds were osmotically primed in polyethylene glycol (PEG
8000) at–1.1 MPa or matrically primed in a ratio of 1.0 g seed: 0.8 g synthetic calcium silicate …
