Storage technique on artificial seeds of Pinellia ternata

Objective: To study the storage technique on artificial seeds of Pinellia ternata.Method: Microtubers were used as experiment materials.By using orthogonal experiment,the sodium alginate,added with GA_3 badistan,chitosan and sodium benzoate,was used as seed vessel.The artificial seeds were stored respectively under 25 ℃ and 4 ℃ for 30 days,then,calculated the germination rate.Result and Conclusion: The sodium alginate(3%)added with GA_3(0.1 mg·L~(-1)),sodium benzoate(0.2%),badistan(1.0%),ClO_2(0.1%) and chitosan(0.2%),were used as artificial seed vessel.Stored under(25±1)℃ for 30 days,and the germination rate was over 65%.The sodium alginate(3%),added with GA_3(0.1 mg·L~(-1)),sodium benzoate(0.2%),badistan(1.0%),ClO_2(0.2%) and chitosan(0.1%),were used as artificial seed vessel.Stored under 4 ℃ for 30 days,and the germination rate was over 80%.
