In order to study the plant growth regulator, using salicylic acid (SA) on germination and growth indices for laboratory research in crop year 2014-2015, which was conducted at the research center Safiabad-Dezful, Khuzestan province. The treatments included four levels of priming with salicylic acid {control (distilled water), 0.7, 1.2, 1.7 mM} in a completely randomized design in three replications. The results showed that the control treatment reduced the decrease in germination time. The highest percentage of germination and related characteristics of the control (distilled water) was obtained. Seed vigor and seedling vigor index were reduced in high concentrations of salicylic acid. The germination percentage of an average daily germination, seed vigor and seedling vigor index had a positive and significant correlation with the daily germination rate showed a significant negative correlation. The results of comparison of treatments showed that the treatment concentration of 0.7 mM salicylic acid highest (22.3 days) and control (distilled water) lowest (0.3 day) had mean germination time. Effects of priming showed the highest mean daily germination (15.44) related to the control and the lowest (2.97) related to the concentration of 7.1 mM salicylic acid. Also, the results showed that the 1.7 mM salicylic acid treatment had the highest number of germinated seeds per day (0.3880) and control treatment had the least number of germinated seeds per day (0.6467). The highest vigor index was observed in control treatment with seedling length of (8.15 cm) and the lowest vigor index was observed in 1.7 mM salicylic acid treatment with seedling length of (1.54 cm). The highest seedling vigor index was observed in control treatment (33.58) and the lowest seedling vigor index was observed in 1.7 mM salicylic acid treatment (17.20). The coefficient velocity germination rate in control treatment was highest (3) and in the 1.7 mM salicylic acid treatment was lowest (0.15). The correlation coefficient between vigor index and seedling vigor index has the highest value (98%). There was a positive correlation between germination percentage and mean daily germination and there was a negative correlation between germination percentage and daily germination speed.
