Abstract :Eremurus spectabilis is a wild edible perennial herbaceous geophyte species with medicinal and popular ornamental uses. In this study, gibberellic acid insert ignore into journalissuearticles values(GA3); with moist-cold stratification treatments were applied to break the dormancy of E. spectabilis seeds. For this purpose, seeds were soaked in gibberellic acid solutions insert ignore into journalissuearticles values(GA3: 500 and 750 ppm for 24 and 48 hours);. Pretreated seeds were then subjected to moist-cold stratification treatments for different durations insert ignore into journalissuearticles values(30, 50, 80 and 100 days); at 4 ºC. In 24-hour GA3 treatments, the germination and emergence ratios insert ignore into journalissuearticles values(21.04%); were obtained from the 500 ppm GA3 dose and 100 days of stratification treatments. In 48-hour GA3 treatments, the GA3 doses did not have any significant effect on germination and emergence ratios; the greatest germination ratios were obtained from the 500 ppm insert ignore into journalissuearticles values(20.36%); and 750 ppm insert ignore into journalissuearticles values(20.00%); doses and 100 days of stratification treatments, and the best emergence ratios were obtained from the 500 ppm GA3 dose and 100 days of stratification treatments insert ignore into journalissuearticles values(18.51%);. It is considered that it is beneficial to try the combinations of moist-cold applications with different treatments in future studies.
