Method for breaking paris polyphylla seed dormancy

Abstract

The invention discloses a method for breaking paris polyphylla seed dormancy. The method comprises the following steps: removing testa of mature paris polyphylla seeds, placing the seeds in a ventilated and shady room to spread and air, placing dry seeds in boiled water cooled to 70-90 DEG C to soak, naturally cooling the water, storing in sand in a room at 18-25 DEG.C and 60-80% relative air humidity after the seeds are swelled; the dormancy of the paris polyphylla seed is effectively broken, the after-ripening period of the seed is shorted, so that the germination time of paris polyphylla seed can be shortened to 60 days from 1 year under the natural condition; the seedling period of the paris polyphylla is shortened, the seedling rate of the paris polyphylla seed is improved, the operation is simple, the cost is low, and any chemical agent is avoided.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicinal materials cultivation, and relates to a method for relieving dormancy of Paris polyphy lla var. yunnanensis (Franch.) Hand.-Mazz. seeds. Background technique [0002] Dianzhong is a plant of the genus Prunus in the family Liliaceae. It is the main raw material for medicines such as Gongxuening, Antiviral Granules, and Jidesheng Snake Tablets. Due to the strong market demand, the wild resources of Dianzhong are sharply reduced and are on the verge of extinction. The long growth cycle of P. dianthus makes artificial cultivation very difficult, especially the long dormancy time of the seeds of P. bottleneck". [0003] When the fruit of Chonglou is mature, the embryo of the seed has not yet differentiated, and the endosperm cells are keratinized, and the starch grains contained in it harden the endosperm tissue, which is not conducive to the entry of air and water, so that the n...

Problems solved by technology

The long growth cycle of P. dianthus makes artificial cultivation very difficult, especially the long dormancy time of the seeds of P. bottleneck"

[0003] When the fruit of Chonglou is mature, the embryo of the seed has not yet differentiated, and the endosperm cells are keratinized, and the starch grains contained in it harden the endosperm tissue, which is not conducive to the entry of air and water, so that the nutrients in the seeds cannot be metabolized and transformed into seeds for germination required nutrients, so the seeds of Chonglou dianthus germinate slowly and have a post-maturation period, which makes the germination of Chonglou dianthus seeds take a long time; rate is also lower

[0004] At present, someone has applied for a patent on the technology of releasing the dormancy of the seeds of the plant, and the patent application document with the patent application number 201110408521.7 discloses "a method for effectively releasing the seeds of the plant". Soak in -3% hydrogen peroxide solution and 200-400mg / L gibberellin solution, take out the soaked seeds and then disinfect them with 70-75% ethanol and 0.1-0.2% mercuric chloride, and finally put the sterilized The seeds were inoculated into 1 / 2MS medium for cultivation, so that the seeds of P. chinensis could germinate in about 3 months at the earliest. Although this method can break the dormancy of seeds of P. edulis and shorten the germination time of seeds, it uses strong corrosive chemicals. It is easy to cause environmental pollution, and the operation is complicated. Finally, it needs to be inserted into the medium for cultivation, and the cost of seed treatment is high
