Abstract: 

Isabgol (Plantago ovata) is an important medicinal plant in world that has more medicinal uses. Germination stage is an important growth plant stage that often affected by environmental stress including water and salinity stress. In order to study germination characteristics of Isabgol in water and salinity stress conditions two laboratory's experiment were conducted. The two experiment were conducted in completely randomized design with 3 and 4 replications for salinity and water stress, respectively. The treatments, for salinity and water stress were six potential (0, -2, -4, -6, -8 and -10 bar) of NaCl and four potential (0, -4, -8 and -12 bar) of PEG respectively. Results of two experimental showed that increasing water and salinity stress decreased significantly germination rate, germination percentage, plumule and radicle length (P<0.01).Zero to -8 bar was the best range for seed germination on Isabgol. The results showed that among of total characters, plumule length is more sensitive to water and salinity stress. It seems that seed germination on Isabgol has more tolerance in salinity stress condition than water stress condition.
