To investigate the methods of dormancy breaking in okra seeds; a study was conducted in the winter season of 2019 under laboratory conditions in Samangan Higher Education Institute. The experiment was carried out based on a completely randomized design within 10 treatments and 3 replications. The treatments included gibberellic acid at 4 levels (100, 500, 700, and 1000 ppm), hot water (70°C), hydrochloric acid (75%) at three levels (5, 10, and 15 minutes), 7-day chilling at 3°C and control treatment (distilled water). The results showed that the highest percentage (100%) with a germination rate of 86 seeds were available due to the application of 7-day cold treatment. Moreover, the treatments such as 7-day chilling, gibberellic acid 500 ppm, and hydrochloric acid 10 and 15 minutes had significant effects on the fresh and dry weight of roots and shoots as well as on their length. we observed that the 7- day cooling at 3°C is the best and most appropriate solution to break down the seed dormancy and stimulate seed germination of the above-mentioned crop.
