The three major types of seed germination tests and the uncertainty of one uncertainty factor's germination test result directly affect the evaluation of the seed quality grade, and at the same time affect the seed operator and user's calculation based on the measured germination rate. Quantity, which in turn affects the immediate interests of seed producers, operators and users. During the process of seed germination test operations, the following aspects should be noted:
Determination of Seed Clarity: Seeds used for germination tests must be clean, free of impurities, and representative. The test of the seed's clarity can be performed using a blast cleanness meter. Only when the degree of clarity is ensured, the germination rate of the seeds can be accurate, and at the same time, the impurities in the seeds are prevented from germinating the seeds during the germination test of the seeds. The impact of the test, while the problem of seed purity, will affect the utilization of the seed.
Determination of germination environment: Each kind of seed has different requirements for germination, and there are certain differences in the temperature, humidity and light intensity requirements of the environment. The seed germination environment can use the seed germination box to operate. He can accurately control the temperature, humidity and light intensity in the environment. In this case, the influence of changes in temperature and humidity in the environment on the seed germination rate is avoided.
Determination of seed germination space: The sand and germinating bed used for seed germination must be sterilized before use, thus avoiding the influence of bacteria in sand and gravel on germination.
Uncertainty of sample and seed lot size: The method of sample sampling is clearly defined in the standard, but the method and arrangement of samples can be neglected. At the same time, the seed volume is not the same, and the impact on seed germination rate can be ignored. Excluding.
