Try many methods like soak them in water, in half ms and gibrellic acid. Try to germinate them in different hormonal combination like kinetin and gibrellic acid, IAA and IBA , cold treatment in 4°C. giving them shaking overnight.
none of this method is successful to break the dormancy
Dear Furrukh
The results of the attached paper depicted synergistic activity of temperature, gibberellic acid and light indicated by improved seed germination, that can be exploited to obtain uniform seed germination under controlled conditions.
First, assessment of seed viability is tested with 1 % solution of TTC. The seeds are kept in TTC solution for 6 h in dark, thereafter the solution is drained off and seeds are washed with distilled water to check staining intensity. The seeds in Petri dishes are lined with Whatman No. 1 filter paper moistened with sterile distilled water.
The most effective treatment is GA3 at 150-500 μg/ml concentration at 25 °C, and continuous light favored germination showing that photoperiod has a significant role.
Try Ethylene and Methylviologen in different treatments. in many cases Methylviologen breaks Dormancy even with ABA Presence.
My new publication is coming shortly on breaking seed dormancy....
