The experiment six sunflower cultivars were studied, the experiment ten seeds of each cultivar (Mehran-1, Mehran-2, Mehran-3, Mehran-4, record and HO-1) were placed on blotting paper and moisture with non-priming control, priming with taped water, 50 mM, NaCl, 100 mM NaCl, 150 mM NaCl and 200 mM NaCl). It was observed that germination percentage of seed affected significantly by the treatments, cultivars, intervals, H x T and T X V, while non-significant for H X V and H X T X V. Further root length was not affected by salinity treatment. Among the cultivars record showed greater root length (52.44mm) while fresh weight and dry weight of root affected significantly by treatments and cultivars. The priming control was not displayed maximum fresh weight of root (0.83g), while it was decreased as NaCl increased. The variety Mehran-I recorded higher fresh weight of root 0.70g, dry weight of root was 0.081g. During the pot experiment two cultivars were evaluated against five treatments indicated that germination of seed differed significantly between treatments, cultivar, and T X C, while non-significant among T X I, C X I and T X C X I. The seed germination reduced significantly as NaCl levels increased, the record showed significantly greater seed germination than Mehran-I increased NaCl significantly reduced number of green leaves and increased number of dry leaves plant-1 in both cultivars. The green leaves were recorded in Mehran-I recorded high root length was (47.24 mm), the fresh weight of root was recorded (0.70g) and dry weight of root was (0.81g).
