How to quickly determine the germination rate of wheat seeds

First, soaking: The wheat seeds soaked in warm water 28-30 °C for 3-5 hours, so that the seeds fully absorb water swelling. Second, cut: Select a representative 100 seeds, with a blade along the seeds of the seeds of the wheat cut into two halves, pay attention to half of the test must be with the embryo. Third, dyeing: First prepare 5% red ink solution. That is, add 19 parts of tap water to 1 part of red ink, mix it, and pour into a petri dish or a porcelain bowl. Then half of the wheat seeds to be measured are evenly distributed into the petri dish, and the amount of the solution is preferably immersed seeds. IV. Rinse: After 5-10 minutes of staining, wash the stained seeds several times with tap water until the rinsed water is not colored. 5. Observing: The embryo or cotyledon of the seed is not colored or only light red, which is a seed with vitality. If the embryo is red, and the degree of endosperm staining is the same, it means that the seed has lost its vitality. 6. Calculation: Count the number of seeds with vitality, and then divide by the total number of seeds for testing, that is, the germination rate of the seeds. China Agricultural Network Editor
