A Dormancy Breaking Technique for Solanum nigrum L.Seeds
There is significant dormancy in Solarium rugrum L. seeds. Treatment with proper chemical agents can be used to break its seed dormancy. Soaking the seeds in H2O2, NaOH, HC1, KNO3 and GA for 24 h increased germination compared to the untreated control. The highest germination rate of over 90% was obtained when the seed was treated with HC1 at 2.25 ~ 36.0 g/L. KNO3 at 40.0 g/L or GA at 200.0 mg/L also increased seed germination to above 80% ,thus these treatments allowed breaking dormancy of S. rugrum L. seeds.
