Study on Breaking Dormancy and Seed Initiation of Astragalus Hedysarum polybotrys Seeds
In order to break the dormancy of Astragalus membranaceus seeds and enhance their germination rate,an experiment was conducted using grinding,H2O2,acid,and alkali treatments to remove hard seeds and initiate germina-tion.The results indicated that Astragalus membranaceus seeds are characterized by high hardness.The most effective method for breaking seed dormancy was treatment with concentrated sulfuric acid for 9 minutes.A combination of 190 mg/L GA3 and 15%PEG for seed initiation yielded a germination rate of 62.20%,a germination potential of 44.30%,and an earlier germination time by 1 day compared to the control.This treatment significantly improved seed value and uniformity.
