Problems solved by technology

Although there is asexual cutting propagation of Tripterygium wilfordii (Chinese Medicinal Materials, 1997, 20 (4): 167-168), the root system of sexually propagated seedlings is developed, and the growth is good and the speed is fast, but there is no relevant sexual reproduction technology at present.

Embodiment 1

[0014] 1. In mid-November every year, the mature fruits of Tripterygium wilfordii of the Euonymus family are collected, dried in the sun, peeled off the husks and arils, and screened to obtain plump seeds;

[0015] 2. Put the harvested seeds in the refrigerator at 4°C for three days, soak the seeds in a mixed aqueous solution of 500ppm gibberellin and 0.3% urea for 3 hours at 30°C, and then raise the temperature to 38°C for soaking 3 hours for seeds;

[0016] 3. Sow the seeds evenly on cotton with a thickness of 2 cm, cover with 3 cm thick fine sand, keep the temperature at 18°C ​​and the relative humidity at 75%, after two weeks, the seeds will germinate and seedlings will be born;

[0017] 4. Transplant the seedlings to the small seedbed. The small seedbed is made of three layers of material, the upper layer is 5 cm thick fine sand, the middle layer is 5 cm thick organic humus soil, and the lower layer is 5-8 cm thick organic humus soil: Activated carbon: fine sand=1:1:1 mi...

Abstract

The present invention relates to sexual reproduction of plant containing tripterine, and is especially seed reproduction process of celastraceae plant containing tripterine. The seed reproduction process including seed treatment, young seedling culture, small seedling culture and field planting in certain conditions is favorable to the growth of root system and the synthesis and accumulation of tripterine. The present invention provides artificial culture technology of plant containing tripterine, and can improve environment while developing wild plant resource.

Description

technical field [0001] The invention relates to a propagation method of Euonymus plants containing tripterine. The method proposes special conditions for seed selection, hormone treatment, germination, seedling cultivation, and planting, fills the gap in the artificial cultivation of tripterygium wilfordii plant resources, and can improve the environmental problems caused by the large-scale development of wild plant resources. Background technique [0002] Tripterygium wilfordii has attracted the attention of international scientists in the past ten years. Tripterygium wilfordii is one of the active ingredients of Euonymus plants such as tripterygium wilfordii and bitter bark vine. Tripterygium wilfordii is widely used in the preparation of Chinese patent medicines in my country, such as tripterygium wilfordii tablets, tripterygium glycosides tablets, triptolide ointment, etc. Tripterygium wilfordii tablets and tripterygium glycosides tablets contain tripterygium, which play...
