Analysis of Germination Rate of Crop Seeds by X-ray Machine

The quality of crop seeds is the basis for the development of agriculture. There are many methods for the inspection of crop seeds, among which the plant X-ray machine can detect a wide variety of crop seeds and even forest tree seeds, and observe the development of hidden pests and germs and germs of seeds. Size, shape, quantity and other aspects are of practical value. In terms of operation, the drawbacks that previously required dark room flushing were changed. Link displays were directly displayed and the best image effects were found for preservation. You can even use USB to connect your computer's high-definition digital image output. You can print, analyze, and store X-ray images directly, call them at any time, connect the printer output, and save money on your washing.

Seeds were extracted from the pure seeds, disinfected with 0.15% formalin, washed with water, and dried in the shade (24 hours). Place seeds on the stage, place labels, and repeat for 4 times. The number of repeat seeds per seed will vary depending on the seed size, usually 25-100 grains (25 large seeds, 50 medium seeds, 100 small seeds) ). The focal distance was adjusted to 3O0mm. In the dark bag, the film was placed in a black paper bag and placed on the stage. The loaded plate was placed on it and exposed according to the best photography conditions of each tree species. With a D-76 developing solution, the ordinary fixing solution is fixed, washed and dried.

The plant X-ray machine photography was used to determine the grade of each tree species, and each class was reasonably accumulated. The value with the smallest difference was used as the estimated germination rate, and the test result was used to determine whether it was feasible. However, there were still certain values ​​between the experimental results. Differences, if measured in large quantities, then statistical analysis may yield better results. According to some tree species contrast ratios, some tree species may obtain more satisfactory results if they conduct contrast photography, but many tree species do not have to use contrast ratio photography to obtain very satisfactory results. Some seed samples are not reasonable due to the process of collection and storage, so the phenomenon of low germination rate is observed. However, it does not affect the accuracy of the test results.
