Salinity stress is an abiotic stress which has harmful effects on germination, growth and yield of alfalfa (Medicago sativa L.) in many parts of the world. Seed priming is a way of increasing salt tolerance of plants. In this study, the effect of seed priming on germination and growth of alfalfa seedlings, Bami cultivar, under salinity condition was investigated. According to germination percentage of seeds under In vitro conditions, salicylic acid, Vitamin B12 and distilled water were selected as primes under salinities of 0, 5 and 10 ds.m-2 NaCl solution for further studies. These studies were carried out in a factorial experiment based on Completely Randomized Design (CRD) with three replications in greenhouse under controlled condition (25°C in day/night). Parameters like percentage and rate of germination, dry and fresh weight of seedling and leaf number were measured. Based on our research All of the treatments (priming, salinity and the interaction of priming with salinity) significantly (p
