چکیده :

In order to study Effect of salinity levels and seed weight on germination of wheat cultivars (BC ROSHAN & ALVAND), an experiment was conducted in the research laboratory of Islamic Azad University- Arak Branch, Iran in 2011. The experimental design was factorial based on completely randomized design (CRD) with three replications. The treatments including of Treatments of wheat seedling cultivars (BC ROSHAN & ALVAND), 1000 weight kernel (22, 32 and 42gr) and Salt stress was inducted by NaCl solution (0, 6 and 12 dc/m) have been used. For this purpose after sterilization of seeds, dried by sterile paper then transferred in to sterile petri dishes and added 10 ml NaCl solution with different concentrations. In this experiment, in standard germination test traits of seed germination percentage, germination rate and in seedling growth test traits of seedling length and dry weight of seedlings have been measured. The results showed salinity decreased seed germination of wheat cultivars in general concentration of NaCl (12 dc/m)and 1000 Weight kernel(22 gr) decreased germination over 40 % as compared with control. also Reduced germination was salient on effect of salinity stress on other treatment.
