In this study, the effects of temperatures of 15 and 25 ° C on the germination characteristics of 7 Tragopogon medicinal plants were studied in a completely randomized design with three replications, at Seed Technology Laboratory of Shahed University, for each species separately in 1398. Results showed that the effect of temperature on different masses was significant in terms of germination percentage, root length, seedling height, seedling dry weight and vigor index. The highest germination percentage belonged to Qom, Isfahan and Tehran masses at 15 ° C. The highest root length was observed for Sanandaj at 25 ° C and the highest seedling height was at Hamadan at 25 ° C. Also the highest dry weight and vigor index of seed belonged to Isfahan mass at 15 ° C and Hamadan mass at 25 ° C, respectively.
