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

Embodiment 1

[0031] a. Remove the outer testa: choose to harvest the seeds when the pericarp of Chonglou dianthus is cracked and the outer testa is shrunk, wrap the fresh seeds with gauze, put them in water, rub them, and rinse them;

[0032] b Drying the seeds: place the seeds of Prunus edulis with the outer testa in a ventilated, shady and cool room, and spread them out to dry naturally;

[0033] c Soaking in boiling water: Put the dry seeds into boiling water that has been cooled to 85°C, let the water cool down naturally, change the tap water once a day, soak for 6 days, and the seeds will swell completely;

[0034] dSand storage treatment: mix the swelled seeds with sand with a water content of 55% in a ratio of 1:3, and place them in an indoor sand storage room with a temperature of 25°C and a relative air humidity of 75%. After 60 days, the seeds germinate, and the germination rate is 98%. %

Embodiment 2

[0036] a. Remove the outer testa: choose to harvest the seeds when the pericarp of Chonglou dianthus is cracked and the outer testa is shrunk, wrap the fresh seeds with gauze, put them in water, rub them, and rinse them;

[0037] b Drying the seeds: place the seeds of Prunus edulis with the outer testa in a ventilated, shady and cool room, and spread them out to dry naturally;

[0038] c Soaking in boiling water: Put the dry seeds into boiling water that has been cooled to 75°C, let the water cool naturally, change the tap water once a day, and soak for 4 days;

[0039] d Sand storage treatment: mix the swollen seeds with sand with a water content of 40% at a ratio of 1:2, and place them in an indoor sand storage room with a temperature of 18°C ​​and a relative air humidity of 60%. The seeds will germinate after 60 days, and the germination rate is 95%. %.

Embodiment 3

[0041] a. Remove the outer testa: choose to harvest the seeds when the pericarp of Chonglou dianthus is cracked and the outer testa is shrunk, wrap the fresh seeds with gauze, put them in water, rub them, and rinse them;

[0042] b Drying the seeds: place the seeds of Prunus edulis with the outer testa in a ventilated, shady and cool room, and spread them out to dry naturally;

[0043] c Soaking in boiling water: Put the dry seeds into boiling water that has been cooled to 70°C, let the water cool naturally, change the tap water once a day, soak for 8 days, and the seeds will swell completely;

[0044] d Sand storage treatment: mix the swollen seeds with sand with a water content of 45% in a ratio of 1:3, and place them in an indoor sand storage room with a temperature of 22°C and a relative air humidity of 80%. After 60 days, the seeds germinate, and the germination rate is 96%. %.

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...
