The germination rate and germination potential of crop seeds are two different concepts and should not be confused. In determining the seed germination rate, it is also necessary to determine the seed germination potential, in order to reasonably and accurately determine the planting area and seeding depth per unit area, so that one seeding preservation seedlings.
Seed germination rate of crops refers to the final period of germination test. The percentage of all normal germinating seeds to the test seeds within the specified date, that is, the germination rate (%): the number of all germinated seeds within the specified date. X100. The number of days for calculating the seed germination rate of crops is: 7 days for corn, wheat, millet, soybean, and sunflower crops, 8 days for sorghum, and 10 days for crops such as rice, mung bean, and peanut.
The germination potential of crop seeds refers to the percentage of normal germinating seeds that accounted for the number of seeds that were supplied during the initial period of the germination test. That is, the germination potential (%) = the number of germinated seed grains in the given days is the number of seeds for the seeding x100. The number of days for the germination potential of various crop seeds is: the seeds of corn, wheat, millet, mung bean, sunflower and other crops are 3 days; and the seeds of rice, soybean, peanut and other crops are 4 days.
