Problems solved by technology

In recent years, wild resources have been over-harvested and dug excessively, making the wild peony in the main producing areas of red peony already endangered and can no longer meet the needs of traditional Chinese medicine. Therefore, the cultivation and tending of wild peony is in urgent need of development.
Because the seeds of Paeoniae Alba have the characteristics of typical double dormancy of hypocotyls, especially the dormancy of the epicotyls is relatively deep, showing characteristics such as slow germination, low germination rate, and long germination period in the production process, which limits the artificial production of wild peony. cultivation

Embodiment 1

[0021] Embodiment 1, making wild peony seeds germinate

[0022] One, prepare rooted wild peony seeds

[0023] The wild Paeonia lactiflora Pall. seeds used in the experiment are wild Paeonia lactiflora seeds collected from Duolun County, Xilin Gol League, Inner Mongolia Autonomous Region. Select seeds with full grains and basically the same size for rooting according to the following method: mix wild peony seeds with sand at a volume ratio of 1:3, keep the humidity of the sand at 50% of the maximum water holding capacity of the sand, store in the sand at 20-25°C After 60 days, rooted wild peony seeds with a main root length ≥ 30mm were obtained.

[0024] 2. Germinate wild peony seeds

[0025] The experiment was repeated three times, and the method of repeating the experiment each time was as follows: the rooted wild peony seeds obtained in step 1 with a taproot length ≥ 30mm and the same length were divided into 4 groups: 25°C stratification treatment for 30 days group, 25°C ...

Abstract

The invention discloses a method for germinating germs of peony seeds. The method for germinating germs of peony seeds comprises the following steps: placing rooting peony seeds in 4DEG C environment, and stratifying obtain stratified rooting wild peony seeds; and sowing the stratified rooting wild peony seeds in a solid matrix, and culturing to obtain germinated peony seeds. The method improves the germination rate of the peony seeds to 89.67%, shortens the germination time to 10d, effectively improves the germination rate of the wild peony seeds and shortens the germination time. The method can be popularized and applied to production in order to solve the problem of long germination time existing in the production process of wild peony, and is of great significance to wild peony plantation and wild resource protection.

Description

technical field [0001] The invention relates to a method for germinating peony seed germs in the biological field. Background technique [0002] Paeoniae Alba has a long history of use and is widely used in the pharmaceutical, food and cosmetic industries. Due to different sources and processing, it is differentiated into Radix Paeoniae Rubra and Paeoniae Alba. Among them, the traditional Chinese medicine Radix Paeoniae Rubra mainly comes from the dried roots of wild populations of Paeonia lactiflora Pall. or Paeonia veitchii Lynch, and is a commonly used traditional Chinese medicine for promoting blood circulation and removing blood stasis, clearing heat and cooling blood, dissipating blood stasis and relieving pain. For a long time, the Radix Paeoniae Rubra in the market has been wild products, and the Radix Radix Radix Paeoniae Rubra produced in Duolun County, Inner Mongolia is used as the authentic medicinal material, which is called "Duolun Radix Radix Paeoniae Alba". ...
