Sunflower seed germination method

Abstract

The invention provides a sunflower seed germination method, and relates to the technical field of sunflower germination. According to the technical scheme, the method comprises the steps that an appropriate amount of sunflower seeds are taken and put into a vessel containing 0.2% KC1 and 150 mg / L gibberellin (GA) treatment fluid; seed soaking is conducted for 8 h at 28 DEG C, and then soaked seeds are taken out; the seeds are wrapped by a wet towel or gauze and then put into a seed germination box at 28 DEG C for 5 d to 7 d. According to the sunflower seed germination method, the germination rate of the sunflower seeds can be obviously increased, and the germination vigor and the seedling fresh quality are improved.

Description

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

Problems solved by technology

[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
