Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a germination method for seeds, and more particularly to a germination method for shortening the germination time of seeds and improving the germination rate.

[0002]

2. Description of the Related Art Various studies have been conducted on seed germination, and many findings concerning factors such as water, air (mainly oxygen), temperature, and light have been disclosed. Among them, water is particularly important because it becomes a medium for a reaction substance related to germination by permeating a predetermined amount into the seed. In fact, many seeds are soaked in water for a predetermined time before sowing.
However, the soaking time varies depending on the type of seeds, and particularly dry seeds such as pulses and those having a hard seed coat such as spinach require a long time. On the other hand, if the water content is relatively high, it will rot if it is immersed for a long time.
In addition, before sowing, it is immersed in chemicals such as bactericide,
There is also a problem that this medicine penetrates into the seeds and contaminates the crops.

[0003]

DISCLOSURE OF THE INVENTION The present inventors can solve the above problems by improving the permeability of water into seeds, and also omit the use of chemicals such as the above bactericides. It is a finding that can be done.

[0004]

The present invention has been made to solve the above-mentioned problems. When sowing seeds, the seeds are immersed in deaerated water from which dissolved gas has been removed for a predetermined time, and A seed germination method characterized by promoting seed germination by improving the water permeability to the seed.

[0005]

Embodiments of the present invention will be described below.

A. Implementation conditions 1. Spinach seeds are divided into two groups of 50 seeds, and each group is immersed in the following water (500 ml each). Group 1: Distilled water (commercial item) Dissolved oxygen concentration = 6.85 pp
m Group 2: Degassed distilled water Dissolved oxygen concentration = 0.24 pp
m Here, the degassed distilled water in which the second group is dipped is commercially available distilled water from which dissolved gas has been removed. In this example,
Although it is obtained by the membrane degassing method, it may be obtained by a heating method or a decompression method. Also, in such degassed distilled water (degassed water), the amount of dissolved oxygen that can be easily measured using a commercially available dissolved oxygen meter etc. will be complicated if the amount of remaining dissolved gas is measured for each gas. Therefore, it is used as the standard for degassing. 2. The soaking conditions of the seeds of each group are 18 hours at a temperature of 15 ° C. 3. The seeds after soaking are sown on a filter paper soaked with distilled water and grown under a temperature condition of 15 ° C.

B. Experimental results 1. The presence or absence of germination and the degree of growth were measured 7 days after seeding, and the results are shown in Table 1. 2. From this table, the germination rate is the second one immersed in degassed distilled water.
The group is excellent, and the root growth after germination is 64% of which is 1 cm or more, and the growth is promoted as compared with the case of using normal distilled water, while the growth failure of 1 cm or less is prevented. You can see that there are 3. The reason for this is as follows. That is,
Degassed water, due to its excellent permeability, easily penetrates into the seed in a sufficient amount in a short time through the seed coat, and after permeating into the seed, it is used as a medium involved in the growth reaction than normal water. Because it works effectively, the seeds are activated and reliably transition to a germinable state. The spinach seeds used in this example are said to be relatively hard and have low water permeability. Next, regarding the growth after germination, at the time of germination described above, the degassed water that has penetrated into the seed is effectively functioning as a medium involved in the growth reaction, and thus the time until germination is shortened. It is considered that the time difference improved the degree of growth after germination.

[0008]

[Table 1]

4. From the above results, by immersing the seeds in deaerated water for a predetermined time prior to sowing, the germination rate can be improved and the growth degree after germination can be promoted. At this time, by immersing in degassed water,
Since it also has an effect of sterilizing bacteria and the like (particularly aerobic bacteria) attached to the surface of the seed, it is possible to omit the conventional dipping in a chemical agent before sowing.

[0010]

As described above, according to the seed germination method of the present invention, when seeds are sowed, the seeds are immersed in degassed water from which dissolved gas has been removed for a predetermined period of time. The germination rate of seeds and the growth rate after germination are improved. This means that the yield at the time of harvesting is improved, and it is extremely useful in the production of agricultural products (so-called agricultural factories) by recent industrial methods. Moreover, according to the present invention, since the seeds are sterilized when the seeds are immersed in deaerated water, it is possible to suppress the amount of chemicals such as bactericides that have been conventionally used for seeds. You can get crops without pollution.
