Embodiment 1

[0029] A method for breaking the dormancy of the seeds of A. japonica and improving the germination rate, the details are as follows:

[0030] A, seed pretreatment

[0031] Select the ripe golden cherry fruit with yellow-red skin, strong and plump, and no pests and diseases harvested from Yulin, Guangxi in mid-October 2020, peel off the outer peel, and then remove impurities and empty shriveled seeds to obtain plump and robust golden cherry 400 seed seeds (100 seeds are a repetition, a total of 4 repetitions), then washed with water for 5 times, and dried at room temperature for later use.

[0032] B. Seed soaking

[0033] Soak the seeds of A. chinensis treated in step A with 5 μmol / L Karrikinolide aqueous solution for 24 hours, soak each 100 seeds with 50 ml Karrikinolide aqueous solution, and soak the 4 replicate groups separately. After soaking, remove the seeds for later use.

[0034] C, low temperature stratification

[0035] The seeds of each replicate group treated ...

Embodiment 2

[0042] A method for breaking the dormancy of the seeds of A. japonica and improving the germination rate, the details are as follows:

[0043] A, seed pretreatment

[0044] Select the ripe golden cherry fruit with yellow-red skin, strong and plump, and no pests and diseases harvested from Yulin, Guangxi in mid-October 2020, peel off the outer skin, and then remove impurities and empty shriveled seeds to obtain plump and robust golden cherry 400 seeds (100 is a repetition, a total of 4 repetitions), then rinsed with water 3 times, and dried at room temperature for later use.

[0045] B. Seed soaking

[0046] Soak the seeds of A. chinensis treated in step A with 8 μmol / L Karrikinolide aqueous solution for 24 hours, soak each 100 seeds with 50 ml Karrikinolide aqueous solution, and soak them separately in 4 repetition groups. After soaking, remove the seeds for later use.

Abstract

The invention discloses a method for breaking the dormancy of the seeds of Chrysanthemum chinensis and improving the germination rate. The method includes: (1) soaking the seeds with 5-10 μmol / L Karrikinolide aqueous solution for 24 hours; (2) mixing the soaked seeds with perlite at a low temperature of 4°C for 30-40 days; (3) soaking the seeds with 5-15 μmol / L The stratified seeds were soaked in an aqueous solution of sodium nitroprusside and 2.5-10 mmol / L hydrogen peroxide for 24 hours; (4) sown in a sand bed. The method of "seed soaking + stratification + seed soaking" is adopted in the method to break the dormancy of the seeds of S. japonica and improve the germination rate, so that the germination rate reaches more than 80%, and the stratification in the traditional method of breaking the dormancy of S. japonicus seeds is greatly shortened. In time, the technical bottleneck of large-scale production of golden cherry seedlings using seeds has been solved.

Description

technical field [0001] The invention belongs to the technical field of cultivation of Chinese medicinal materials, and in particular relates to a method for breaking the dormancy of seeds of Chrysanthemum chinensis and improving the germination rate. Background technique [0002] Jinyingzi is the dried and ripe fruit of Rosa laevigata Michx., a plant of the Rosaceae family. It is an important medicinal material in the field of traditional Chinese medicine. , spleen deficiency diarrhea, rheumatoid arthritis and other diseases. Modern pharmacological studies have found that golden cherry seeds have hematopoietic, blood-activating, softening arterial, detoxifying and antibacterial effects, and have inhibitory effects on influenza viruses. Some key ingredients in western medicine also need to be extracted from golden cherry seeds. With the increasing demand for golden cherry seeds in the pharmaceutical market in recent years, and the current situation of large-scale production ...
