Description

A Seed Vertical Germination Observation Device

technical field

The utility model relates to a vertical germination observation device for seeds, in particular to a vertical germination device which can directly observe and measure the length of roots and buds.

Background technique

In the prior art, the method used for seed germination is usually to put the seeds into a petri dish to moisten and germinate. The disadvantage is that during the germination process, the seeds that can be placed in the petri dish are limited, and most of the seeds in the petri dish are only It can be placed horizontally, so that the root system is usually intertwined in a surrounding state, and it cannot grow upright so that the root length of the germination of the seed cannot be measured conveniently and accurately, and the germination rate of the seed cannot be calculated intuitively, and the germination rate is the seed germination rate. an important indicator of . Therefore, it is impossible to directly and accurately measure the germination root length and shoot length of seeds by adopting petri dish to germinate seeds.

Contents of the invention

The purpose of the utility model is to provide a vertical seed germination observation device, which has a simple structure and is easy to use, can germinate seeds in large quantities, and can clearly observe and measure the length of germinated roots and buds.

The technical scheme of the utility model: a device for observing vertical germination of seeds, which includes splints, filter paper is arranged between the splints, and the splints clamp the filter paper through clamping parts.

In the aforementioned device for observing vertical germination of seeds, the splint is vertically placed in the culture solution container, and the filter paper is in contact with the solution in the culture solution container.

In the aforementioned device for observing vertical germination of seeds, more than one row of splints are arranged in the culture solution container.

In the aforementioned device for observing vertical germination of seeds, the splint is a transparent glass plate or a plastic plate.

In the aforementioned device for observing the vertical germination of seeds, the seeds to be germinated are placed on the filter paper in the splint.

The beneficial effect of the utility model is that the use of transparent splints can clamp multiple seeds, and the culture solution container can also place multiple rows of splints, so a large number of seeds can be germinated in a specific solution, and the germination can be observed conveniently and clearly. state, not only can accurately measure the length of roots and shoots, but also ensure that the roots and shoots remain vertical. Compared with the existing germination method, it has the following advantages: 1. It can maintain the vertical growth of root system and buds without affecting the gravitropic growth of plants. 2. It can clearly observe and measure the length of roots and shoots, and calculate the seed germination rate. 3. The operation is simple and easy, and the seeds can be germinated in large quantities under the same solution.

Compared with the wetting and germination of the petri dish, the method of the utility model will not affect the seeds with germination ability due to external conditions, so that the germination rate of the seeds can reach 100%, and can be directly observed and counted.

Detailed ways

Embodiment of the present utility model: a kind of seed vertical germination observation device, as shown in Figure 1 and 2, adopts transparent glass plate or plastic plate to make splint 1, and splint 1 is 2 pieces, wherein a splint 1 is slightly thick, and thickness can Choose between 1-10 mm, mainly play the role of fixed support, another splint 1 plays a clamping role, it can be slightly thinner, put a piece of filter paper 2 between the splints 1, and the splint 1 will pass through the clamping part 4 Filter paper 2 is clamped.

Put the splint 1 vertically into the growth liquid container 5 to ensure that the filter paper 2 is in contact with the growth liquid solution 6 in the growth liquid container 5 . More than one row of splints 1 can be placed in the growth solution container 5, which is convenient for large-scale operations. The inside of the growth solution container 5 can be provided with a card slot, which is convenient for fixing the splint 1 .

Place the seed 3 to be germinated on the filter paper 2 in the splint 1, the seed 3 can be provided with a plurality of, the spacing between the seeds 3 is properly placed according to the germination needs, through the applicant's experiment, the spacing between the seeds 3 is greater than 2 centimeters, which is conducive to The growth of seeds.

When in use, place a piece of transparent plastic board horizontally as the splint 1, then place the filter paper 2 after absorbing water flat on the splint 1, then place the seeds 3 to be germinated on the filter paper 2 at a certain distance and height, and then cover with another A transparent plastic splint 1 is clamped with clamping parts 4 on both sides, and finally the whole splint 1 is put vertically into the growth solution container 5 containing the growth solution 6 .

When measuring the length of the root system of the seeds, place the plastic plate with the germinated seeds horizontally under a camera with a fixed focal length to take pictures, and use a ruler to place it within the shooting range for comparison. The root shoot length of the seed germination can be clearly shown in the photo. By analyzing the pixel points of the root length and shoot length in the photo and comparing the pixel points of the unit distance of the ruler, the unit length of the root length and shoot length of the seeds in the photo can be converted.

Taking wheat germination as an example, in the germination of ordinary petri dishes, the wheat root system grows horizontally and circles in the horizontal surface of the petri dish, it is difficult to judge whether the seeds have germinated, and the root shoot length cannot be directly measured. Vertical germination can maintain the gravity of plant growth, and the root system will not be entangled with each other due to the horizontal direction, so it is easier to visually observe whether the seeds germinate and produce root shoots, and can clearly measure the length of the root shoots.
