Method of preservation and germination acceleration of primrose seeds

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...

Problems solved by technology

[0003] The present invention aims at the existing problems: primrose seeds are small, have low activity and short lifespan, and the preserved old seeds will not germinate or have a very low germination rate in the second year of sowing, which is a technical difficulty in primrose planting; Moreover, temperature, humidity, light and water content in seeds during seed preservation and germination play a vital role in the germination rate of primrose seeds; at present, there is no relatively standardized and unified breeding and planting method for primroses, which can effectively improve Storage time and germination rate of primrose seeds
