Composite initiator for improving activity of deteriorated seeds of angelicae dahurica and application of composite initiator

Abstract

The invention discloses a composite initiator for improving the activity of deteriorated seeds of angelicae dahurica and an application of the composite initiator. The seeds of angelicae dahurica are subjected to initiation treatment through NaCl, KNO3 and PEG in different proportions, and influence of different kinds of initiation treatment on the activity of the deteriorated seeds of angelicae dahurica is analyzed by measuring germination indexes and physical indexes of the seeds subjected to different kinds of initiation treatment. Experimental results indicate that after the seeds of angelicae dahurica are subjected to initiation treatment through the composite initiator in the best treatment combination, the germination rate, the germination potential, the germination index, the activity index, soluble protein and the POD activity of the seeds of angelicae dahurica are all increased to different extents, and the electric conductivity is reduced. With the adoption of the composite initiator, damaged membrane systems of the deteriorated seeds are improved and restored, the electric conductivity of leaching liquor of the deteriorated seeds is reduced, the content of the soluble protein is increased, the POD activity and the seed vigor are improved, and a basis is provided for sowing of the seeds of angelicae dahurica in a field as well as drug production.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a composite initiator for improving the vigor of degenerated seeds of Angelica dahurica and its application. Background technique [0002] Angelica dahurica is Angelica dahurica (Fisch.ex Hoffm.) Benth.et Hook.f or Hang Baizhi Angelica dahurica (Fisch.ex Hoffm.) Benth.et Hook.f.var.formosana (Boiss.) Shan et The dry root of Yuanyuan is used as medicine with the root. It is warm in nature, fragrant in taste, pungent and slightly bitter, and returns to the stomach, colon and lung meridian. Angelica dahurica is an authentic medicinal material produced in Sichuan. It is mainly produced in Suining, Sichuan, and scattered in Ziyang, Nanchong, Luzhou, Dazhou and other places. Its output is high, accounting for more than 70% of the total output of Angelica dahurica in China. In addition to supplying the domestic market, it is also exported to Hong Kong, Southeast Asia, Japan, Eu...
