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

A kind of germination method of sunflower seeds

Technical field

The present invention relates to Helianthi Germination Technique field, particularly relate to the germination method of a kind of sunflower seeds.

Background technology

The most domestic research for the Germination Technique of sunflower seeds is the most on the low side, the most general just use or to The Stratification technique of day certain herbaceous plants with big flowers seed, Main is: at the container of cleaning, loading 50 ~ 55 DEG C of warm water, the water yield is the 5 of seed volume Times, seed immersed in warm water and be stirred continuously, when water temperature drop to 30 DEG C, stopping stirring, then soak 8 ~ 12 hours, make kind Son suctions moisture, then water outlet, drains away the water, and binds up with gauze, and outside wraps the piece of sack or towel soaked again, puts in basin alms bowl Carrying out accelerating germination, this method is referred to as hoting water treatment of seeds, and this is the most the most frequently used germination accelerating method, and this method is simple and convenient, but also There are problems: seed sprouting is slow, and bud gesture is weak, it is irregular to emerge, big seedling phenomenon is serious, such as seed dormancy, emerges Speed is slower, and bud rate is low.Helianthi is a kind of very popular fruit, occupies critical role on producing, but Helianthi kind Son germinates slow and irregular, and in storage process, easy naturally-aged causes vigor to reduce, and the most how to accelerate seed germination and rush Enter seed sprouting and seem particularly significant.

Summary of the invention

It is an object of the invention to provide the germination method of a kind of sunflower seeds, it can significantly improve sending out of sunflower seeds The fresh and alive quality of bud rate, germinating energy and sprout.

In order to solve the problem in the presence of background technology, the present invention is by the following technical solutions:

First take appropriate sunflower seeds to be put in the container containing 0.2%KC1 and 150mg/L gibberellins (GA) treatment fluid；

Soak seed 8 hours under 28 degree celsius temperature, then seed is taken out；

Put in the seed germination box of 28 degrees Celsius after wrapping up with wet towel or gauze, through 5-7 days.

Compared with the conventional method, the inventive method beneficial effect following points:

1, with batch sunflower seeds, the seed processed by this method, can improve the bud rate of bud rate 5%-8%.

2, with batch sunflower seeds, the seed processed by this method, germinating energy can be emerged 93% for 5 days, be improved 4 hundred Branch.

3, with batch sunflower seeds, the seed processed by this method, sprout quality significantly improves, fresh and alive strong shape, lives Power is strong.

4, with batch sunflower seeds, the seed processed by this method, Phase ofsprouting improves, and Seedling size is uniform.

Detailed description of the invention

A kind of germination method of sunflower seeds, its detailed description of the invention and principle are as follows:

It is to be understood that the processing method of seed germination, first understand seed germination: sub-sprouting refers to what seed started from imbitition A series of orderly physiological process and morphogenetic process, sprouting of seed needs suitable temperature, certain moisture, sufficient Air, during seed germination, is first water suction, makes seed coat expand, softens, more oxygen visible through the seed coat can be made to enter after seed immersion Entering Interior Seed, carbon dioxide visible through the seed coat is discharged simultaneously, and the physical state of the inside changes；Next to that air, seed exists The vital movement of the series of complex conducted in germination process, only seed are constantly breathed, and obtain energy, Cai Nengbao Being normally carried out of card vital movement；Being finally temperature, temperature is too low, and photosynthesis weakens significantly, and Repiration is suppressed, light Symphysis productivity reduces, the decomposition of Interior Seed nutrient substance and other a series of physiological activities, is required at a suitable temperature Carry out.

The present invention uses the principle that 0.2%KC1+150mg/L gibberellins (GA) processes: gibberellins (GA) is as a kind of plant Regulator, can break seed dormancy, accelerates Starch Hydrolysis in endosperm, promotes germination, and potassium is the monovalence that plant part is required Cation, it is dissolved in water with ionic condition, and its major function is relevant with plant metabolism, and the present invention is in Yu Xiang The impact of mda content in certain herbaceous plants with big flowers germination characteristic and sprout body, improves the sprouting condition of sunflower seeds, can quickly have The raising germination percentage of sunflower seeds, germinating energy and the fresh and alive quality of sprout of effect.

Concrete operation method: take appropriate sunflower seeds and be put in containing 0.2%KC1 and 150mg/L gibberellins (GA) treatment fluid In container, soak seed 8 hours under 28 degree celsius temperature, then seed is taken out, put into after wrapping up with wet towel or gauze In the seed germination box of 28 degrees Celsius, through 5-7 days, seed will fully be sprouted.
