Different Salts Effects on the Germination of Hordeum vulgare and Hordeum bulbosum

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.
