Abstract:
Objective A new breed of licorice seeds(Wuxin No.1) was selected from wild licorice,Glycyrrhiza uralensis.Methods Its germination rate,content of soluble protein,and peroxidase(POD) activities were investigated and compared with the wild licorice seeds(control group).The leaves of Wuxin No.1 were collected and its genetic polymorphism was analyzed by inter-simple sequence repeat technique(ISSR).Results The results suggested that the seed vitality in Wuxin No.1 was higher than that in the control group.The change of soluble protein and POD activity also demonstrated that the seeds in Wuxin No.1 have the higher vigor.ISSR Analysis showed that among 22 random primers used in this experiment,six primers generated different DNA band types,which meant that there was genetic polymorphism in Wuxin No.1.Conclusion All these changes indicate that Wuxin No.1 is a prospective domestication species of licorice and may be cultivated widely in the future.
