n order to study effects of salt and drought stresses on germination of weed african rue (Peganum harmala) two separate test based on completely randomized design with four replications in Agricultural Research Laboratory University of Birjand was implement in 1392.were salinity and drought of levels, respectively, at nine levels (0 (distilled water), 3, 6, 9, 12, 15, 18, 21 and 24 ds/m) and (0 (distilled water), -0/1, -0/2, -0/4, -0/6, -0/8, 1 and -1/2 Mpa).Polyethylene glycol was used for drought and sodium chloride was used for salinity Result showed that effects of drought and salinity stress on germination rate and percentage of seeds was significant. In experiments related to drought stress, there was highest percentage (95%) and germination rate (7.74 seed per day) in control treatment. In experiments related to salinity stress, observed the highest percentage of germination (98%) in treatment 3 dS/m. Was highest germination rate in the control treatment and with increasing concentrations of salinity levels of control treatment to 24 dS/m, decreased germination rate as much as 96.1%.
