CN105917798A - Rape seed germination method - Google Patents

Abstract

The invention discloses a rape seed germination method, and relates to the technical field of rape germination. The method comprises the following steps: putting a proper amount of rape seeds in a container provided with a 0.2% KCl and 150mg/L gibberellic acid (GA) treatment fluid; soaking the seeds at 28DEG C for 8h, and taking out the seeds; and wrapping the seeds by using a wet towel or gauze, putting the wrapped seeds in a 28DEG C seed germination box, and allowing the seeds to stand in the seed germination box for 5-7d. The method can obviously improve the germination rate and the germination energy of the rape seeds, and also improves the fresh and alive quality of bud seedlings.

Description

A kind of germination method of Semen Brassicae campestris

Technical field

The present invention relates to Brassica campestris L Germination Technique field, particularly relate to the germination method of a kind of Semen Brassicae campestris.

Background technology

The most domestic research for the Germination Technique of Semen Brassicae campestris is the most on the low side, the Stratification technique of the most general still Semen Brassicae campestris just used, Main is: at the container of cleaning, load 50 ~ 55 DEG C of warm water, the water yield is 5 times of seed volume, seed immersed in warm water and be stirred continuously, stirring is stopped when water temperature drop to 30 DEG C, soak 8 ~ 12 hours again, seed is made to suction moisture, then water outlet, drain away the water, bind up with gauze, outside wraps the piece of sack or towel soaked again, accelerating germination is carried out in putting basin alms bowl, this method is referred to as hoting water treatment of seeds, this is the most the most frequently used germination accelerating method, this method is simple and convenient, but there is also problems: seed sprouting is slow, bud gesture is weak, emerge irregular, big seedling phenomenon is serious, such as seed dormancy, speed of emergence is slower, and bud rate is low.Brassica campestris L is a kind of very popular fruit, occupies critical role, but Semen Brassicae campestris is germinateed slow and irregular on producing, and in storage process, easy naturally-aged causes vigor to reduce, and the most how to accelerate seed germination and promotes that seed sprouting seems particularly significant.

Summary of the invention

It is an object of the invention to provide the germination method of a kind of Semen Brassicae campestris, it can significantly improve the fresh and alive quality of the germination percentage of Semen Brassicae campestris, 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 Semen Brassicae campestris 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 Semen Brassicae campestris, the seed processed by this method, can improve the bud rate of bud rate 5%-8%.

2, with batch Semen Brassicae campestris, the seed processed by this method, germinating energy can be emerged 93% for 5 days, be improved 4 percentage points.

3, with batch Semen Brassicae campestris, the seed processed by this method, sprout quality significantly improves, fresh and alive strong shape, energetic.

4, with batch Semen Brassicae campestris, 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 Semen Brassicae campestris, its detailed description of the invention and principle are as follows:

It is to be understood that the processing method of seed germination, first seed germination is understood: sub-sprouting refers to a series of orderly physiological process and the morphogenetic process that seed starts from imbitition, sprouting of seed needs suitable temperature, certain moisture, sufficient air, during seed germination, first it is water suction, makes seed coat expand after seed immersion, soften, more oxygen visible through the seed coat can be made to enter Interior Seed, carbon dioxide visible through the seed coat is discharged simultaneously, and the physical state of the inside changes；Next to that air, the vital movement of seed series of complex conducted in the germination process, only seed is constantly breathed, and obtains energy, being normally carried out of guarantee vital movement；Being finally temperature, temperature is too low, and photosynthesis weakens significantly, and Repiration is suppressed, and photosynthetic productivity reduces, the decomposition of Interior Seed nutrient substance and other a series of physiological activities, is required for carrying out at a suitable temperature.

The present invention uses the principle that 0.2%KC1+150mg/L gibberellins (GA) processes: gibberellins (GA) is as a kind of plant modifying agent, seed dormancy can be broken, accelerate Starch Hydrolysis in endosperm, promote germination, potassium is the monovalent cation that plant part is required, it is dissolved in water with ionic condition, its major function is relevant with plant metabolism, the present invention is in the impact of mda content in Semen Brassicae campestris germination characteristic and sprout body, improve the sprouting condition of Semen Brassicae campestris, the germination percentage of Semen Brassicae campestris can be improved fast and effectively, germinating energy, quality fresh and alive with sprout.

Concrete operation method: take appropriate Semen Brassicae campestris and 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, seed will fully be sprouted.
