Problems solved by technology

At present, although artemisinin can be artificially synthesized, it is expensive and has not yet been put into production. The only source of artemisinin is still isolated and extracted from Artemisia annua plants
[0003] At present, the storage of Artemisia annua seeds is stored at room temperature like most other plant seeds, but for Artemisia annua seeds, the seed life of this room temperature storage is very short, and with the prolongation of storage time, the germination rate of Artemisia annua seeds is greatly improved. decreased; if the storage period of Artemisia annua seeds is more than 8 months, its activity is almost completely lost, and the germination rate is almost zero
Therefore, in the process of artificially cultivating Artemisia annua, the field germination rate of Artemisia annua seeds is very low, which has become a bottleneck restricting the production of Artemisia annua.

Embodiment 1

[0053]The storage method of Artemisia annua seeds, firstly, sieve and select plump, disease-free, and mature seeds from freshly harvested seeds with tidbits and impurities; then wrap the Artemisia annua seeds with cloth bags, The seeds are stored in a cold storage at 4°C; during storage, checks are made every half a month to keep the seeds dry and non-absorbent, and to prevent water accumulation and rodent damage.

[0054] Before the seeds selected by the present embodiment were stored, their germination rate was 90%; after 60 days, their germination rate was 89%; after 120 days, their germination rate was 89%; after 180 days, their germination rate was 88.5%; After 240 days, its germination rate was 88%, after 420 days, its germination rate was 88%, and after 730 days, its germination rate was 85%.

[0055] The effect of present embodiment storage is the best.

Embodiment 2～6

[0057] See Table 6 for the storage method, storage temperature and wrapping materials of Artemisia annua seeds, and others are the same as in Example 1.

Abstract

The invention provides a method for storing seeds of southernwood, which is characterized in that the seeds of the southernwood are refrigerated under a temperature below 5 DEG C. The method of the invention effectivly prolongs the service life of the seeds of southernwood, and a higher germination percentage of the seeds of the southernwood are maintained. The method ensures a high activity and germination percentage of seeds after being stored for 24 months; but seeds stored at ambient temperature for 24 months loss activities completely, and the germination percentage is 0.

Description

technical field [0001] The invention relates to a method for treating seeds, in particular to a method for storing artemisia annua seeds. Background technique [0002] Artemisia annua (Artemisia annua L.) is an annual or perennial herbaceous plant of the genus Artemisia in the family Asteraceae. It tastes bitter, pungent, and cold in nature. Fever, bone steaming labor fever, malaria cold and heat, etc., is one of the traditional antimalarial drugs of traditional Chinese medicine. A large number of physical and chemical tests, pharmacological studies and clinical application studies at home and abroad have shown that artemisinin, one of the effective extracts of Artemisia annua, is an active ingredient in antimalarials, and has now become an antimalarial drug recommended by the World Health Organization, especially for cerebral infarction. Malaria and chloroquine-resistant malaria have a good effect. At present, although artemisinin can be synthesized artificially, it is ex...
