The germination responses of Hordeum ulgare seeds
to saline stress caused by different salt types was studied. For this,
25 seeds of mentioned species were placed on filter paper in Petri dishes
containing distilled water (control), 60, 120, 180, 240, 300, 360 and
420 mM. saline solution of NaCl, CaCl2 an KCl. The results
indicated that saline levels effects were significant (P < 0.05) for
seed germination percentage, seed germination velocity, mean time to germination,
length of the stem and radicle and seed vigour. Seed germination decreased
significantly by increasing salinity levels. Also, the results showed
that H. vulgare is more tolerant than H. vulgare against
salinity in germination stage.
