Embodiment 1

[0018] A method for preserving and accelerating germination of primrose seeds, comprising the following steps:

[0019] (1) Pretreatment: Put the picked primrose seeds into conical flasks and seal them with ethylene, which can moisturize and accelerate ripening, improve the storage time and germination rate of seeds, store them at 4°C for 3.5 hours, and reduce the temperature of seeds. Metabolism level, reduce the consumption of nutrients in the seeds, and then use potassium permanganate solution to sterilize to prepare sterilized primrose seeds;

[0020] (2) Seed soaking: Bake the sterilized primrose seeds at a low temperature of 44°C for 13 minutes to appropriately reduce the water content in the seeds, which can increase the storage time of the seeds. Immerse them in the functional liquid for 9 seconds, take them out and bake them for 3 minutes, and repeat the dipping, Baking twice can form a protective layer on the surface of the seeds, which can maintain the moisture cont...

Embodiment 2

[0030] (1) Pretreatment: Put the picked primrose seeds into the Erlenmeyer flask and seal with ethylene, which can moisturize and accelerate the ripening, improve the storage time and germination rate of the seeds, store them at 5°C for 4 hours, and reduce the metabolism of the seeds level, reduce the consumption of nutrients in the seeds, and then use potassium permanganate solution to sterilize to obtain sterilized primrose seeds;

[0031] (2) Seed soaking: Bake the sterilized primrose seeds at a low temperature of 45°C for 14 minutes to appropriately reduce the water content in the seeds, which can increase the storage time of the seeds. Immerse them in the functional liquid for 10 seconds, take them out and bake them for 4 minutes, and repeat the dipping, Baking for 3 times can form a protective layer on the surface of the seeds, which can maintain the moisture content inside the seeds, improve the ability of the seeds to maintain activity during storage, and impregnate the...

Abstract

The invention discloses a method of preservation and germination acceleration of primrose seeds. The method includes steps of: 1) pretreatment: placing picked primrose seeds in a conical flask and feeding ethylene, and sealing the conical flask to preserve the primrose seeds at low temperature, and performing sterilization; 2) seed soaking: baking the sterilized primrose seeds at low temperature,and impregnating the seeds in a functional solution and then baking the seeds, impregnation and baking being carried out repeatedly for 2-3 times; 3) preservation: heating camellia oil, adding the impregnated primrose seeds and dried camellia oil to the conical flask, sealing the conical flask and storing the conical flask at low temperature; 4) activation: washing the stored primrose seeds in anhydrous ethanol, and performing temperature-varying activation by soaking the seeds in a plant fermenting solution; 5) germination acceleration: adding gibberellins and indoleacetic acid to the plant fermenting solution and stirring and mixing the components, and soaking the activated seeds in the mixture to perform the germination acceleration.

Description

technical field [0001] The invention belongs to the technical field of primrose planting, and in particular relates to a method for preserving and accelerating germination of primrose seeds. Background technique [0002] Primula is a perennial herbaceous plant belonging to Primulaceae of the family Primula. Its rhizome is inclined or flat, and many fibrous roots are issued downward. The scape can grow up to 30cm high. It blooms every month and bears capsules in June. Primrose is a traditional flower variety in my country, with its elegant and gorgeous flower colors, often used in flower beds, rockery, gardens, living rooms and living rooms to increase the landscape and decorate the indoor environment; its wild plants are mainly distributed in Heilongjiang, Jilin and eastern Inner Mongolia, etc. It is also distributed in Japan, Korea and Siberia. Primrose is a warm-temperate plant and is used to growing in moist open fields, ditch edges and forest edges, but it is not resist...
