Background

Lonicera caerulea L.var.edulis Turcz.ex Herd.is a variety of Lonicera caerulea of Lonicera of Caprifoliaceae. The tree shape is beautiful, the flower and the fruit can be observed, the drought resistance and the cold resistance are strong, and the tree is rare and excellent landscaping tree species. The oval purple berry has high edible value and medicinal value, is sour, sweet and delicious, contains 7 amino acids and vitamin C, can be eaten raw, can extract pigment, and can be used for brewing wine, making beverage and jam. The Lonicera edulis plant contains aucubin, has the effects of clearing away damp-heat, promoting urination, relieving pain, reducing blood pressure, protecting liver, resisting tumors and the like, can promote stem cell regeneration, obviously inhibits the replication of hepatitis B virus DNA, has a certain curative effect on treating infantile anorexia, and has extremely high economic value. The seed contains active substances such as rutin and anthocyanin, and has effects of resisting oxidation, resisting allergy, scavenging free radicals in vivo, inhibiting lipid peroxidation and platelet aggregation, preventing diabetes, reducing weight, and protecting vision.

At present, the cost of cutting propagation and tissue culture propagation of lonicera caerulea is high. In the prior art, the germination acceleration of the lonicera caerulea is realized by mixing sand and seeds, digging a pit outdoors in winter for storage for about 3-4 months, and taking out the mixture for sowing in a field, and the germination acceleration method has low germination rate of about 65 percent. Although the cost of sowing and breeding in the field is low, the emergence rate of germinated seeds is about 70 percent even in the growth process due to the restriction of climatic factors. This results in a low yield of lonicera caerulea, which cannot be put into practice in large quantities.
