Embodiment 1

[0040] A method for rapid germination of wild flax seeds of the present invention comprises the following steps:

[0041] (1) Seed collection and selection: wild flax seeds were collected in July of that year, immature seeds and impurities were manually picked out, and dried at room temperature. The collected mature wild flax seeds are dark brown or dark brown in color, and the seeds are collected before falling off.

[0042] (2) Low temperature treatment: The selected seeds are stored at 0°C and 30% relative humidity for 25 days.

[0043] (3) Disinfection: Disinfect the low-temperature-treated seeds with 2% sodium hypochlorite disinfectant for 10 minutes, and then rinse them with sterile water.

[0044] (4) Seed soaking in warm water: Soak the seeds treated in step (3) in warm water at 37°C for 9 minutes.

[0045] (5) Transplant: use a sterilized petri dish as a germination bed, put 2 layers of filter paper in the petri dish, soak it with distilled water, put the wild flax se...

Embodiment 2

[0051] A method for rapid germination of wild flax seeds of the present invention comprises the following steps:

[0052] (1) Seed collection and selection: Mature wild flax seeds were collected in August of that year, immature seeds and impurities were manually picked out, and dried at room temperature. The collected mature wild flax seeds are dark brown or dark brown in color, and the seeds are collected before falling off.

[0053] (2) Low temperature treatment: The selected seeds are stored at 4°C and 35% relative humidity for 30 days.

[0054] (3) Disinfection: Disinfect the low-temperature-treated seeds with 2% sodium hypochlorite disinfectant for 10 minutes, and then rinse them with sterile water.

[0055] (4) Seed soaking in warm water: Soak the seeds treated in step (3) in warm water at 45°C for 8 minutes.

[0056] (5) Transplant: Use a sterilized petri dish as a germination bed, put 2 pieces of filter paper in the petri dish, soak it with distilled water, put the w...

Embodiment 3

[0062] A method for rapid germination of wild flax seeds of the present invention comprises the following steps:

[0063] (1) Seed collection and selection: Mature wild flax seeds were collected in September of that year, immature seeds and impurities were manually picked out, and dried at room temperature. The collected mature wild flax seeds are dark brown or dark brown in color, and the seeds are collected before falling off.

[0064] (2) Low temperature treatment: The selected seeds are stored at 3°C ​​and 32% relative humidity for 20 days.

[0065] (3) Disinfection: Disinfect the low-temperature-treated seeds with 2% sodium hypochlorite disinfectant for 10 minutes, and then rinse them with sterile water.

[0066] (4) Seed soaking in warm water: Soak the seeds treated in step (3) in warm water at 45°C for 10 minutes.

[0067] (5) Transplant: use a sterilized petri dish as a germination bed, put 2 layers of filter paper in the petri dish, soak it with distilled water, put...

Abstract

The invention provides a method for promoting rapid germination of wild flax seeds. The method comprises the following steps: (1), collecting the seeds; (2), treating the seeds at low temperature; (3), disinfecting the seeds; (4), soaking by using warm water; (5), transplanting; (6), performing germination culture: performing light irradiation culture in a container in the step (5) until the seedsare white; (7), forming seedlings: adding a 1 / 2 MS nutrient solution or a 1 / 2 Hoad land nutrient solution into the container until the wild flax seeds germinate and grow. The wild flax seed germinating method provided by the invention is simple, easy to implement and free of complex operation, and according to the wild flax seed germinating method, the germination and seedling formation of the wild flax seeds can be quickly and effectively promoted and the germination rate of the wild flax seeds is increased to 90.24% or above. The method has an important significance in accelerating reproduction, preserving excellent wild flax resources, extracting DNA for molecular-level research, using the wild flax resources for discovering excellent genes and broadening the genetic basis of flax, performing genetic research on the flax and improving the variety.

Description

technical field [0001] The invention belongs to the technical field of seed germination, and in particular relates to a method for promoting rapid germination of wild flax seeds. Background technique [0002] wild flax ( Linum perenne L. ) belonging to the Linaceae ( Linaceae ) Flax ( Linum ) Perennial herbaceous plants, perennial wild perennial flax native to Central Europe, Eastern Europe, the Near East, and Siberia. According to the records of Flora of my country, there are 9 known species in China. In addition to cultivated species, 8 closely related species are distributed in many places , but more in Northwest, Northeast, North China and Southwest China. Since the 1980s, there have been research reports on the collection of wild flax, such as Changbai Mountain in Jilin, Lindian in Heilongjiang, Bashang in Hebei, Zhangbei in Hebei, Xinjiang, Qinghai, Qilichuan in Shaanxi, etc., in Tianzhu County and Huining County in Gansu Wild flax seeds have been collected in ,...
