[0038] Example 1
[0039] This embodiment provides a multifunctional and convenient testing device for rice seed variety purity, seed viability, and seed germination tests. This device allows for efficient seed counting and simplifies seed placement. When used for testing rice seed variety purity and seed viability, the device can also quickly wash away excess dye and reduce chemical reagent damage. When used for rice seed germination tests, the device ensures adequate water supply and effectively reduces the spread of mold contamination and root entanglement during germination. The specific solution is as follows:
[0040] A seed quality testing device includes an outer box 1, a seed soaking plate 12, a dyeing cover 15, and a germination test trough 18;
[0041] The seed soaking plate 12 has multiple placement slots 13 for placing seeds, the dyeing cover 15 has a first opening 16 corresponding to each placement slot 13, and the germination test tank 18 has a second opening 20 corresponding to each placement slot 13.
[0042] The seed counting and soaking plate 12 is connected to the dyeing cover 15 to form a seed counting and soaking box 21, which is placed in the outer box 1 when testing the seed variety purity and / or seed viability.
[0043] The seed soaking plate 12 is connected to the germination test tank 18 to form a germination test box 22, which is placed in the outer box 1 when a seed germination test is conducted.
[0044] As attached Figure 1 and attached Figure 2 As shown, this embodiment provides a highly efficient and multifunctional seed quality inspection device, including a sturdy and durable outer box 1, a seed counting and soaking plate 12, a dyeing cover 15, and a germination test tank 18. The seed counting and soaking plate 12 has multiple evenly distributed placement slots 13. In practical applications, the seed counting and soaking plate 12 has 10×10 evenly distributed elliptical slots for placing seeds, as shown in the attached diagram. Figure 4As shown, each slot has an elliptical opening at the bottom, and the inside of the slot is surrounded by walls with the side walls pointing vertically upwards. Furthermore, the size and shape of the slot 13 can be customized and adjusted according to the specifications of the seeds to be tested, which facilitates subsequent operations and observation.
[0045] The dyeing cover 15 has first openings 16 that precisely correspond to the placement slots 13 on the seed soaking plate 12. These first openings 16 allow the specific dyeing solution or treatment liquid to evenly penetrate the seeds in each placement slot 13, effectively testing the seed's varietal purity or viability. Furthermore, the germination test tank 18 also has second openings 20 that correspond to the placement slots 13. These second openings 20 allow the seeds to undergo germination tests under suitable growth conditions after dyeing or other pretreatment, enabling precise monitoring of the germination status of each seed and providing accurate data for seed quality assessment.
[0046] Specifically, in some embodiments of this application, the seed counting and soaking plate 12 has a length of 130mm and a width of 100mm; the placement groove 13 has a major diameter of 8mm, a minor diameter of 4mm, and a depth of 4mm; the opening in the placement groove 13 has a major diameter of 5mm, a minor diameter of 1mm, and a thickness of 2mm; the dyeing cover 15 has a length of 129mm and a width of 98mm; the first opening 16 has a major diameter of 5mm, a width of 1mm, and a thickness of 2mm; the germination test groove 18 has a length of 129mm and a width of 98mm; and the second opening 20 has a major diameter of 10mm, a width of 6mm, a height of 70mm, and a thickness of 2mm. Of course, there are no limitations on the specific specifications of the seed counting and soaking plate 12, the opening in the placement groove 13, the dyeing cover 15, the first opening 16, the germination test groove 18, and the second opening 20; they can be set and adjusted according to actual needs.
[0047] In practice, the seed counting and soaking plate 12 and the dyeing cover 15 are detachably and tightly connected to form a seed counting and soaking box 21. This combination allows the entire seed counting and soaking box 21 to be safely placed in the outer box 1 for necessary processing and analysis when testing seed variety purity and / or seed viability. Furthermore, the seed counting and soaking plate 12 is connected to the germination test tank 18 to form a germination test box 22. This conversion process is simple and quick, requiring no seed movement and effectively avoiding seed damage or confusion during processing. The germination test box 22 is then placed in the outer box 1, providing a stable and suitable environment for germination testing until the final quality assessment results are obtained. This achieves efficient and rapid seed counting, soaking, dyeing, washing, and uniform seed placement, thereby reducing labor intensity and human error, and providing strong support for comprehensive seed quality testing.
[0048] In some embodiments of this application, the specific verification steps are as follows:
[0049] (a) Testing of variety purity
[0050] (1) Several types of soaking
[0051] Place the evenly mixed seeds on the seed soaking plate 12, and sweep them with your hand to make the rice seeds stick into the placement tank 13, so that one rice seed is placed in each of the 100 tanks.
[0052] Align the dyeing cover 15 with the first sliding part 14 on the seed counting and soaking plate, push the dyeing cover handle 17, and lock the seed counting and soaking box 21 containing the seeds.
[0053] Place the seeds into the outer box body 6, where the lid 2 is already secured. Pour in clean water up to the mark 8. Cover the lid 2 with the sealing element 4 installed. Secure the outer box lid clip 5 and the outer box slot 7. Soak the seeds for 6 hours.
[0054] Loosen the outer box cover latch 5, take out several seeds from the soaking box 21 through the dye cover handle 17, and pour out the clean water.
[0055] (2) Dyeing and washing
[0056] Place the seed soaking box 21 with the lid 2 already secured into the outer box body 6, pour in the dyeing solution to the mark 8, close the lid 2 with the sealing part 4, secure the outer box lid buckle 5 and the outer box slot 7, and dye for 24 hours.
[0057] After the dyeing is complete, loosen the outer box buckle 5, open the outer box cover 2, take out several seed soaking boxes 21 through the dyeing plate handle 17, and discard the dyeing solution inside the outer box.
[0058] Add clean water to the outer box 6 containing the soaking box 21 up to the scale line 8, and wash the seeds inside the soaking box 21.
[0059] After washing, place filter paper at the bottom of the outer box 6, then place several seed soaking boxes 21 with the lid 2 secured on top, cover the lid 2 with the sealing element 4, and secure the outer box buckle 5 with the outer box slot 7.
[0060] (3) Statistical analysis of staining
[0061] After 24 hours, loosen the buckle 5, open the box cover 2, take out several seeds from the soaking box 21, and push the handle 17 to remove the dyeing cover 15.
[0062] The staining of seeds within 12 minutes of soaking was recorded by taking photos with a camera. The images were then processed using image processing software such as ImageJ to statistically analyze the staining of the grains as unstained, light brown, brown, dark brown, and black.
[0063] After the experiment, clean the device and keep it clean.
[0064] (II) Testing of Seed Viability
[0065] (1) Several types of pre-wetting
[0066] This step is the same as several seed soaking methods used in the varietal purity test, with a pre-wetting time of 12 hours.
[0067] (2) Staining
[0068] After pre-wetting, push the handle 17 to remove the dyeing cover, longitudinally cut the seed containing the embryo and most of the endosperm, and place it back into the placement tank 13. Push the handle 17 to lock the seed soaking box 21 containing the seeds. Place the seed soaking box 21 with the lid 2 already locked into the outer box body 6, pour in the dyeing solution to the mark 8, close the lid 2 with the sealing element 4, and lock the outer box lid buckle 5 and the outer box slot 7. Dye for 0.5-1 hour.
[0069] (3) Statistical identification
[0070] After staining, the staining of the cross-section of several seeds within 12 soaking plates was recorded by taking pictures with a camera. The images were then processed using automatic image processing software such as ImageJ, and the staining of the radicle and scutellum of the grains was statistically analyzed.
[0071] (III) Seed germination test
[0072] (1) Disinfection and sterilization
[0073] The germination test equipment and this device are first boiled in steam or water for 30 minutes or autoclaved for more than 15 minutes.
[0074] (2) Several types of soaking
[0075] This step is the same as several types of seed soaking in the test of variety purity. Take out the vent hole 10 and the inner hole plug 11 of the outer box, and soak the seeds in water at 30℃ for 24 hours.
[0076] (3) Assemble the germination test device
[0077] Slide out the dyeing cover 15 and push several seed soaking plates 12 into the germination test tank 18 so that the elliptical opening of the placement tank 13 corresponds one-to-one with the germination test partition 20, and assemble it into a germination test box 22.
[0078] Add clean water to the water tank 9 until it is just full. Place two layers of filter paper inside, ensuring the edges of the filter paper are submerged in the water. Place the assembled germination test box 22 on the filter paper and secure the outer box clip 5 to the outer box slot 7. Place the device in a 30℃ incubator for the germination test. Regularly check the water level in the water tank. If the water level is low, add an appropriate amount of clean water through the vent 10.
[0079] After the germination test is completed, loosen the outer box buckle 5 and open the outer box cover 2. Use a camera to take pictures to record the germination status of the seeds in the germination test box 22. Use automatic image processing software such as ImageJ to process the pictures, and count the germination status separately. When identifying the aging degree of grain and oilseed quality, fresh sprouts breaking through the seed coat (commonly known as showing white) are considered to be normally germinated grains.
[0080] In one specific embodiment, as shown in the appendix Figure 3 As shown, the outer box 1 includes a lid 2 and a body 6. A slot 7 is provided on the body 6 near the lid 2, and a buckle 5 matching the slot 7 is provided on the lid 2 near the body 6. The lid 2 connects to the slot 7 via the buckle 5, thus connecting the lid 2 and the body 6 and ensuring the integrity and sealing of the outer box 1. In practical applications, to facilitate the connection between the lid 2 and the body 6, a lid slot 3 matching the slot 7 is also provided on the lid 2. The lid slot 3 enhances the stability of the connection between the lid 2 and the body 6, and also makes closing the two smoother, reducing operational difficulties caused by misalignment, making the entire opening and closing process of the outer box 1 more convenient and efficient.
[0081] In one specific embodiment, the outer box 1 further includes a sealing element 4, which is disposed on the lid 2 and / or the body 6 to seal the outer box 1 when the lid 2 is connected to the body 6. The sealing element 4 effectively reduces the leakage of toxic and harmful dyeing solutions such as phenol, better protecting the health of laboratory personnel. Specifically, in some embodiments of this application, to balance good sealing performance and cost-effectiveness, the sealing element 4 is selected as a rubber ring, effectively ensuring a tight seal.
[0082] In one specific embodiment, the seed counting and soaking plate 12 is provided with a first sliding part 14, and both the dyeing cover 15 and the germination test tank 18 are provided with a second sliding part that matches the first sliding part 14, so that the dyeing cover 15 is slidably connected to the first sliding part 14 through the second sliding part, thereby realizing the connection between the dyeing cover 15 and the seed counting and soaking plate 12, or
[0083] The germination test trough 18 is slidably connected to the first sliding part 14 via the second sliding part, thereby connecting the germination test trough 18 to the seed soaking plate 12. This sliding connection method not only simplifies operation but also greatly enhances the flexibility and practicality of the equipment.
[0084] In one specific embodiment, as shown in the appendix Figure 4 As shown, there are evenly distributed placement grooves 13 on the seed soaking plate 12, and each placement groove 13 has a through hole at the bottom; the shape of the placement groove 13 and / or the through hole includes elliptical.
[0085] In practical applications, the seed soaking plate 12 has 10×10 evenly distributed oval slots for placing seeds. Each slot has an oval opening at the bottom to facilitate even soaking of the seeds and promote the circulation of water or air when needed. The oval design not only conforms to the natural shape of the seeds, providing more stable support and reducing the possibility of rolling or displacement, but also provides a more suitable space for seed growth. The inside of the slots has four surrounding walls with vertical side walls. Furthermore, the size and shape of the placement slots 13 can be customized and adjusted according to the specifications of the seeds to be tested, facilitating subsequent operations and observation.
[0086] In one specific embodiment, the outer box 1 is provided with at least one vent 10 for ventilation and / or water inlet, and a plug 11 for sealing the vent 10. The vent 10 has the dual function of ventilation and / or water inlet, which allows good air circulation inside the outer box 1, while also providing the necessary humid environment, thereby meeting the oxygen and moisture requirements of different seeds during germination or storage.
[0087] In addition, to ensure that the vents 10 can effectively isolate external environmental interference when not needed, such as preventing dust, insects, or other contaminants from entering, and to maintain the airtightness of the internal environment in certain situations, the outer box 1 is also equipped with a vent plug 11. This allows users to flexibly control the opening or closing of the vents 10 according to actual needs, thereby ensuring that the outer box 1 can provide an optimal growth or storage environment for the seeds.
[0088] In one specific embodiment, as shown in the appendix Figure 5 and attached Figure 6 As shown, the germination test trough 18 is equipped with a separating groove 19 for dividing the openings. The separating groove 19 can separate the openings within the test trough, thereby ensuring that each seed in each opening has an independent growth space. The separating groove 19 effectively prevents the seed roots from tangling together during growth. Such tangling can not only hinder normal seed growth but also cause root damage, affecting the final germination rate. Secondly, the separating groove 19 can also significantly reduce the risk of seed cross-infection due to mold. In a germination test, if one seed becomes moldy, the mold produced can easily spread to other seeds through the soil or air, leading to the failure of the entire test. The presence of the separating groove 19 can effectively block this transmission path, protecting other seeds from infection.
[0089] In one specific embodiment, as shown in the appendix Figure 7 As shown, a handle 17 for easy operation is provided on the side of the dyeing cover 15 away from the seed soaking plate 12. The handle 17 facilitates the connection and separation of the seed soaking plate 12 and the dyeing cover 15, improving the efficiency of operation.
[0090] In one specific embodiment, the outer surface of the outer box 1 is provided with a transparent portion, on which are scale lines 8 for displaying the water level. The scale lines 8 clearly and precisely mark different water level heights, thus providing clear guidance for researchers when soaking seeds and adding dyeing solution. By reading the scale lines 8, the water level inside the outer box 1 can be easily monitored, ensuring that the soaking depth of the seeds or the amount of dyeing solution added is optimal. This improves operational accuracy, greatly simplifies the user's operating procedures, and makes the soaking and dyeing process more intuitive and convenient.
[0091] In one specific embodiment, to meet the seed's water requirements during the germination test and ensure that the seeds can grow under optimal humidity conditions, the outer box 1 is equipped with a water storage tank 9. The water storage tank 9 can store sufficient water to support normal seed growth during the germination test, greatly reducing the frequency of manual watering and saving a significant amount of time. If additional water is needed during the germination test, it can be quickly and conveniently added through the ventilation holes 10 on the outer box. This ensures the continuity and stability of the test and also improves operational convenience.
[0092] The purpose of this application is to provide a multifunctional and convenient testing device for rice seed variety purity, seed viability, and seed germination testing. This device allows for efficient seed counting and simplifies seed placement. When used for testing rice seed variety purity and seed viability, the device can also quickly wash away excess dye and reduce chemical reagent damage. When used for rice seed germination testing, the device ensures adequate water supply and effectively reduces the spread of mold contamination and root entanglement during germination. This application achieves efficient and rapid seed counting, soaking, dyeing, washing, and uniform seed placement, thereby reducing labor intensity and human error, and providing strong support for seed quality inspection.
[0093] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the embodiments.
