Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seed germination rate inspection adhesive sheet used for seed germination rate inspection of vegetables, flowers and the like, and more particularly to a seed germination rate inspection adhesive sheet suitable for efficient seed germination rate inspection.

[0002]

[Prior art]

 At present, seed germination companies are conducting germination rate tests as one of the seed quality tests. As an inspection method, for example, filter paper is laid in a petri dish as a germination bed, a certain number of seeds (usually 50 or 100) are placed on it, and a predetermined amount of water is supplied to the germination rate. Has been adopted. At this time, although an automatic seeder such as a partial suction type is used as a means for counting and arranging the test seeds, most of the work is done manually, so much time and labor is required. And needed.

In order to solve the above problems, the inventors of the present invention have previously developed a seed germination rate inspection pressure-sensitive adhesive sheet in which a point adhesive is applied to one surface of a water-absorbent sheet-shaped substrate. Was proposed (Actual application No. 1-088381).

[0004]

[Problems to be solved by the device]

 As a filter paper used as a germination bed in the above germination rate test, qualitative filter paper (such as qualitative filter paper No. 2 (thickness 0.26 mm) manufactured by Toyo Roshi Kaisha, Ltd.) is usually used. The amount of water supplied during the test varies depending on the size of the germination bed, the difference in seed items, etc.However, if water absorption and water retention are not constant, the germination characteristics will be affected. Two sheets are stacked and used as a germination bed. In the seed germination rate inspection pressure-sensitive adhesive sheet, since the filter paper is used as the substrate, it is necessary to lay another filter paper under the sheet for the same reason as above. was there.

An object of the present invention is to provide a pressure-sensitive adhesive sheet for seed germination rate inspection, which is suitable for solving the problems of the above-mentioned conventional techniques and for efficiently performing seed germination rate inspection. It

[0006]

[Means for Solving the Problems]

 The above-mentioned object is a pressure-sensitive adhesive sheet for seed germination rate test, wherein an adhesive is provided on one surface of a sheet-shaped water-absorbent support (filter paper, etc.), and the thickness of the sheet-shaped water-absorbent support is 0.5 to 1.0 mm. This can be achieved by using a pressure-sensitive adhesive sheet for inspecting seed germination rate.

In addition, by providing the above-mentioned dot-shaped adhesive on intersections of vertical and horizontal lattices on the support, and by making the area per adhesive one area for mounting one test seed, Work can be made more efficient.

[0008]

[Action]

 By setting the thickness of the sheet-shaped water-absorbent support used as the base material in the range of 0.5 to 1.0 mm, the specified water supply amount (4 to 4 8 ml), sufficient water absorption and water retention can be obtained with only the base material. When a filter paper with a thickness of 0.5 mm or less is used as the base material, it is insufficient in terms of water absorption and water retention for a given water supply amount, and sometimes the seeds become submerged. It will adversely affect the germination characteristics. Therefore, another sheet of the same material should be laid under the base material. In addition, when the thickness of the base material is 1.0 mm or more, the amount of water required for the test is simply given, and it is not particularly effective for improving the efficiency of the germination rate inspection work. Rather, it is disadvantageous in terms of manufacturing or price.

The size of the dot-shaped adhesive provided on the intersections of the vertical and horizontal lattices on the base material is changed according to the type of the test seed, and the test seed according to the size of the dot-shaped adhesive is changed from above. By spraying and then removing excess seeds, it is possible to easily mount one seed per adhesive.

【Example】

 Hereinafter, the pressure-sensitive adhesive sheet for inspecting seed germination rate of the present invention will be specifically described with reference to Examples.

[0011]

Embodiment 1 FIG. 1 is a perspective view showing the constitution of an embodiment of an adhesive sheet for inspecting seed germination rate of the present invention. In the case of this embodiment, a 0.74 mm-thick filter paper (Toyo Roshi Kaisha, Ltd.) is used as the water-absorbent support 1. (Manufactured by Co., Ltd.) was used, and the adhesive 2 having a diameter of 1 mm was applied in dots at regular intervals on the intersections of the vertical and horizontal lattices on the support.

FIG. 2 is a cross-sectional view showing a state in which the pressure-sensitive adhesive sheet of FIG. 1 is placed in a container 3 such as a petri dish and the test sample 4 is mounted on the pressure-sensitive adhesive 2. In the case of the present embodiment, the test seed is tested. Tomato seeds were used as No. 4, and the seeds were sprayed from above the adhesive sheet, and then the container 3 was shaken, and then the container 3 was tilted to remove the residual particles. It was possible to mount one grain at a time.

As a result of subjecting the above sample to a germination rate test, a germination rate of 96% could be obtained.

[0014]

[Comparative Example 1] Qualitative filter paper No. 2 (manufactured by Toyo Roshi Kaisha, Ltd., thickness: 0.26 mm) was used as a base material, and tomato seeds were applied to a seed germination rate inspection pressure-sensitive adhesive sheet with a point adhesive of 1 mm in diameter. As a result of mounting the qualitative filter paper No. 2 underneath and carrying out a germination rate test, a germination rate of 95% could be obtained.

[0015]

[Comparative Example 2] Qualitative filter paper No. 2 (same as above) was used as a substrate, and tomato seeds were mounted on an adhesive sheet for seed germination rate inspection in which the diameter of the point adhesive was 1 mm, and the seeds were used for germination rate inspection. As a result, only a germination rate of 63% could be obtained.

[0016]

[Effect of device]

 As described above, by using the adhesive sheet for seed germination rate inspection as the adhesive sheet of the configuration of the present invention, it is possible to solve the problems of the prior art and efficiently perform seed germination rate inspection. It was possible to provide a pressure-sensitive adhesive sheet for inspecting seed germination rate suitable for.
