The main factors affecting the seed germination rate measurement and their solutions

Seed germination rate refers to the percentage of normal seedlings grown in the specified conditions and time to the number of seeds for inspection, which is an important indicator of seed quality inspection. The germination rate of a batch of seeds is of great significance both to the seed's management activities and agricultural production. In the process of seed germination test, there are mainly the external environment and the internal conditions of the seed itself which affect the seed germination test. Here is a brief look at it.

First, the external environmental impact. This is nothing more than the influence of temperature, oxygen, humidity, and light intensity in some seed environments. Different plants have different requirements for the above. However, the germination of seeds will be affected by these factors. This is unchanged. Moisture is a key factor in seed germination. Seeds must absorb enough water to germinate, but too much water will increase the chance of seed mildew and infection. Oxygen and temperature are important factors affecting the bud germination. The light intensity is determined by the seed's response to light. These factors are all quite changeable in the natural environment. When the seed germination test is conducted, if the amount of germination is small, the seed germination box is directly used for the test. However, when conducting large-scale experiments, the temperature, humidity, and light intensity in the environment are measured and regulated. The temperature and humidity measurement can use a temperature and humidity monitor, and the light intensity measurement is performed directly using an optical quantum meter to operate. They measure and regulate to create an environment suitable for seed germination.

Second, internal factors. This is the quality of the seeds, such as the net moisture content and maturity. The seeds are to be examined before the seed germination test. When the test is performed, a certain amount is taken for measurement, and a thousand particles are taken for measurement to calculate the percentage, and after these tests are passed, the test is performed. Germination test. Individuals are advised not to use what they think when taking seeds, and it is considered to be more time consuming and labor-intensive. They can be operated using a photoelectric counting instrument.

The seed germination test is an important indicator in the quality inspection of seeds, but it should be noted that the high seed germination rate does not necessarily mean that the seeds have a high germination potential.
