A composite initiator for improving the vigor of Angelica sinensis seeds and its application

Abstract

The invention discloses a composite initiator for improving the vigor of degenerated seeds of Angelica dahurica and its application. The present invention uses different ratios of NaCl, KNO 3 The seeds of Angelica dahurica were primed with PEG, and the effects of different priming treatments on the vigor of the deteriorated seeds of Angelica dahurica were analyzed by measuring the germination indexes and physiological indexes of seeds with different priming treatments. The experimental results showed that the germination rate, germination potential, germination index, vigor index, soluble protein and POD activity of Angelica dahurica seeds were increased to varying degrees after being primed with the compound initiator of the optimal treatment combination, and the electrical conductivity decreased. The composite initiator of the present invention not only improves and repairs the damaged membrane system of deteriorating seeds, reduces the conductivity of deteriorating seeds leaching solution, increases the content of soluble protein, enhances POD enzyme activity, and improves seed vigor, but also can be used for field sowing of Angelica dahurica seeds. And provide the basis for the production of medicinal materials.

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...
