• Pericarp• Pre-treatments at five different temperatures 10% NaOCl (+water control) and pericarp removal Gravel sand: 5, 10, 15, 20 and 25oC, 2.rep (n=12) Peat: 15oC, 2.rep (n=12)

Domestication potentials of seakale

Experimental methods

• Pericarp removal, sown in peat, 15oC• 10, 15 and 20oC, 4 replicates (n=50)• 10 h of light with 50µmol m-2s-1

• Measuring: started on day 5, 2-4d.• Germination, radicle ≥ 2 mm• Infection, mycelium-like structure

Blue: germinated seeds

Red: infected seeds
