Germination method of sunflower seeds

Abstract

The invention discloses a germination method of sunflower seeds, and relates to the technical field of germination of sunflowers. The germination method adopts the following technical scheme: taking a moderate number of sunflower seeds, putting the seeds in a container containing 0.2% KC1 and 150 mg / L gibberellin (GA) treating fluid; soaking the seeds for 8 hours at the temperature of 28 DEG C, and taking the seeds out; after wrapping the soaked seeds with wet towels or gauze, placing the seeds in a seed germinating box for 5-7 days at the temperature of 28 DEG C. The germination method can obviously improve the germination rate, germinative force and sprout-stock fresh quality of sunflower seeds.

Description

technical field [0001] The invention relates to the technical field of sunflower germination, in particular to a sunflower seed germination method. Background technique [0002] At present, there are relatively few researches on the germination technology of sunflower seeds in China, and the germination technology of sunflower seeds is generally adopted in the industry. The main method is: put warm water at 50~55℃ in a clean container, and the water volume is 5% of the seed volume. double, soak the seeds in warm water and stir continuously, stop stirring when the water temperature drops to 30°C, and then soak for 8-12 hours to make the seeds absorb enough water, then drain the water, wrap it with gauze, and then wrap the outside Put soaked sacks or towels in pots for germination. This method is called soaking seeds in warm soup. This is the most commonly used method for germination at present. This method is simple and convenient, but there are many problems: slow seed e...

[0002] At present, there are relatively few researches on the germination technology of sunflower seeds in China, and the germination technology of sunflower seeds is generally adopted in the industry. The main method is: put warm water at 50~55℃ in a clean container, and the water volume is 5% of the seed volume. double, immerse the seeds in warm water and stir continuously, stop stirring when the water temperature drops to 30°C, and then soak for 8-12 hours to make the seeds absorb enough water, then drain the water, wrap it with gauze, and then wrap the outside Put soaked sacks or towels in pots for germination. This method is called soaking seeds in warm soup. This is the most commonly used method for germination at present. This method is simple and convenient, but there are many problems: slow seed emergence, bud vigor Weak, irregular seedling emergence, serious phenomenon of seedling size, in case of dormant seeds, the emergence speed is slower, and the germination rate is low

Sunflower is a popular fruit that plays an important role in production, but sunflower seeds germinate slowly and irregularly, and are prone to natural aging during storage, resulting in reduced vitality. Therefore, how to speed up seed germination and promote seed emergence is very important
