Abstract

Isabgol (Plantago ovata) is an important medicinal plant in world that has more medicinal uses. Germination stage is an importance of growth plant stage that often effective by environmental stress including water and salinity stress. In order to study germination characteristics of Isabgol in water and salinity stress conditions were conducted two laboratories experimental. The two experimental were conducted in completely randomized design with 3 and 4 replications for salinity and water stress respectively. The treatment, for salinity and water stress was six potential (zero, -2, -4, -6, -8 and -10 bar) of NaCl and four potential (zero, -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
