Baz? Dormansi K?rma Uygulamalar?n?n ve S?cakl???n Sak?z Geveni’nin (Astragalus gummifer Labill.) Tohum Canl?l??? Üzerine Etkileri

This research was carried out to determine the effects of germination temperature and 12 dormancy breaking applications on seeds gum tragacanth (Astragalus gummifer Labill.) bush. The in Field Crops Department laboratory, I?d?r University Faculty Agriculture, 2019. Gum were germinated for 28 days dark at constant temperatures 10, 15, 20, 25 °C variable 20/10 °C, 20/15 25/10 25/15 °C. As a result research, highest total rate determined 10.7% temperatures. It that there 89.3% seeds. Then, methods (matrix priming, hydro gibberellic acid (GA3, potassium nitrate, cold, moist stratification, warm warm+cold cold+warm cold water, hot mechanical scarification, chemical scarification) applied. After made, again At end study, it revealed percentage with 50.7% obtained from application water 2 minutes. On other hand, matric acid, scarification did not have any effect removing status
