objective: in order to investigate effects of different concentrations of poly amines sprimidin and putrescine on germination of arg cultivar under salinity stress. methods: this experiment was conducted as factorial based on completely randomized design with four replicates in agronomy and plant breeding laboratory, agricultural department, islamic azad university, varamin-pishva branch in spring of 2014. first factor was four levels of salinity including s1: 3.87, s2: 5.95, s3: 10.25 and s4: 12.87 ds/m and the second factor was three levels of poly amines including h0: control (not application of poly amines), h1: putrescine 2.5 m/mol and h2: sprimidin 5 mmol/l. coleoptile and cleorhiza length, cleorhiza number, coleoptile, cleorhiza and seedling dry weight, tissue water content (twc), germination percent and number of damaged seeds were measured. results: analysis of variance showed that coleoptile and cleorhiza length, cleorhiza dry weight affected by salinity and hormone levels at 1% of probability level. there was no significant difference among other treatments for other properties. results of this experiment indicated that following increasing salinity, sever reduction in germination-dependent properties were observed.
